AMD Ryzen 7 3700X: Zen 2 in all its glory


The first processor microarchitecture Zen was released in March 2017. Since it’s only been two and a half years, but today, AMD is updating the lineup of its desktop processors that inherit this microarchitecture for the second time. Moreover, it is not about the formal updates. Let appeared in last year Ryzen second generation and can be calculated by a simple translation of the initial design on rails for a more advanced technological process, but now we are talking about much more significant change. New Ryzen third generation, we are talking about today, is not just advanced technological process, but also significant changes in the topology and microarchitecture.

AMD acts decisively and quickly: time after time she makes strides toward improving their proposals. And the results are not forced himself to wait. The company is steadily increasing its share of the processor market, and Ryzen second generation deservedly reputed to be the best proposals for the mass market on a combination of price and performance. And even the skeptics now believe that AMD has managed to seriously shake up the CPU market and make at least so that announcements of new processors from mediocre updates turned into the main events in the computer industry.

However, now the company wants even more. While Intel continues to torment the 14-nm process technology and microarchitecture Skylake come from 2015, AMD is going to finally seize the initiative. At Ryzen third generation has the mission to demonstrate the technological superiority of AMD and translate it from second place to first. But will the third attempt improved AMD to create the best in recent history processor for desktop systems successful?

We write these lines, when you already know the test results. And I can say for sure, Ryzen in 3000 there is a lot of positive changes that put them head and shoulders above its predecessors. However, challenges remain, which subject the story of the novelties turns out not too simple.

For this reason, the material on testing Ryzen 3000 we broke into two parts. In the first part we talk about the new osmeteria Ryzen 7 3700X, the example which is easiest to analyse design compared Ryzen previous generation Intel Core. The second part, which will be released following the first, will be devoted to testing the 12-core flagship Ryzen 9 3900X with which AMD is going to put in the mass market segment a series of absolute records.

#What you should know about the new microarchitecture Zen 2

If the release of processors Ryzen first and second generation AMD wanted to convey the idea that she finally returned to the top League of developers and manufacturers of x86 processors, today’s announcement Ryzen 3000 brings already a completely different message. Now the company puts before itself a more ambitious goal – to become the leader of the processor market, which offers the fastest, most energy efficient and most technologically advanced chips.

And this task seems impossible. In the past year, AMD managed to build a very solid Foundation from which she is able to confidently start up. Thanks to the cooperation with one of the leading contract manufacturers of semiconductors, Taiwan’s TSMC, the first company in the PC industry shifted the production of its processors for the 7-nm technology, which allowed it to increase the density of the crystals to raise their operating frequencies and, in parallel, to improve energy efficiency. In addition to this, AMD has introduced another innovation and moved to a new mnogoshipovyh (cabletow) the layout of processors, which suggests the Assembly of final products of several semiconductor crystals, which allows to circumvent many manufacturing complexity and significantly reduce the cost of complex multi-core processors.

But Ryzen third generation mark so highly not only because they are able to offer the users a lot of working at high frequency cores for a relatively small amount. Something similar already was in the range of AMD before. But based on previous arm processors, there were many claims with low single-threaded performance with serious delays in the internuclear interaction and the inefficient memory controller. Now, all these deficiencies in varying degrees, should be eliminated. Speaking about the improvement of the performance of new Ryzen in comparison with the predecessors, AMD operates two-digit percentages, and it really seems very serious progress against the background of development in recent years Intel.

However, you need to understand that this major increase in performance Ryzen third generation is largely driven by the low base effect. The new processor microarchitecture is not something fundamentally new: 2 Zen is different from Zen/Zen+ is, in fact, carries with it a set of fixes for the most critical problems of its predecessors. But because of the problems of a different sort were many, and many of them caused considerable damage to the overall efficiency of the microarchitecture, their removal ultimately leads to significant productivity gains.

And yet, to belittle the merits of AMD, we would not like. The ultimate in Zen 2, there have been many positive changes: increased throughput on-chip all major highways, increased download of available processor cores of the computing resources become more amounts of data that the processor can operate locally, as well as significantly increased key performance indicator specific performance microarchitecture – the number of executable per clock instructions (IPC).

Detailed analysis the analysis of the architectural innovations and improvements in Ryzen 3000 we have dedicated a separate article in it about the structure of micro Zen 2 describes in great detail.

Here we only recall the main causes that determine the growth of the notorious figure of the IPC. They need to know at least in order to better understand the results of the tests representatives of the family Ryzen 3000. So this:

  • Increase the width of the block floating point unit (FPU) from 128 to 256 bits. Thanks Zen 2 can execute a 256-bit AVX2 instructions in one go, that is twice as faster than previously.
  • A two-fold increase in cache decoded micro-operations, which should reduce the downtime of the Executive part of the conveyor due to the lack of performance of the decoder of x86 instructions.
  • Significantly improved the prediction of transitions in the mechanism which is now used new TAGE predictor (Tagged geometric) and increased by the amount of buffers for the purposes of branchings of the first and second levels. All of this reduces the error probability of the branch prediction and minimizes the number of situations when the processor is forced to reset the pipeline state from-for incorrectly made predictions of branching code.
  • The appearance of an extra (third) of the block address generation (AGU), which allows the execution units more timely access to necessary data even at high loads.
  • Doubled bus width of the cache memory that also allows you to eliminate bottlenecks when handling the actuators to the data.
  • Double volume cache of the third level, the total amount of which made up 32 MB for each eight-chiplet.
  • Advanced algorithms pre-fetch data, enabling transfer of data from memory into the cache before they are requested during the execution of the program code.
  • Increased the size of the queue schedulers that allowed us to improve the efficiency of the SMT technology.
  • Increased the size of the register file, which gives the processor the ability to process more commands in parallel without any delay.
  • Additional fixes in microarchitecture that help to neutralize the attacks, the Spectre V4 without impacting performance.

To illustrate the micro-to improve the practical examples is quite simple. For this we usually use a simple synthetic benchmark test of AIDA64 utility: they allow you to see how performance has changed in the performance of certain standard algorithms. In the figures below we compare the past generation Ryzen (Pinnacle Ridge) with the current (Mattisse) for example shestnadcatiletnih and eight-core chips running at the same clock frequency of 4.0 GHz. In addition, the chart is placed the results of eight Lake Coffee Refresh, also clocked at 4.0 GHz.

In fact, all these results are very curious. First, they show that for some algorithms, microarchitecture Zen 2 provides almost two-fold performance increase, while in other cases, the performance remained at the same level. Second, they allow to say that in terms of a relatively simple computational algorithms, which are well rasparallelivanija and do not need in active work with external data from memory, microarchitecture Zen 2 has not only grown to the efficiency of the microarchitecture of Intel Skylake, but even surpassed it.

The most impressive progress Matisse shows in those algorithms which use floating point. Specifically, where used instructions AVX2, FMA3, and FMA4. After all, it is their performance in Zen 2 has doubled.

As for integer calculations, with them, no problems there in previous processors Ryzen. Now there was a small change in performance, associated primarily with changes in the caching and decoding of instructions with a decrease of the L1I cache and increase the cache decoded micro-operations. Not to mention the relatively poor result of Matisse in the CPU Photoworxx test. The fact that it is the only benchmark in which among other things plays a role in the performance of the memory subsystem. And with it a new Ryzen really is not as good as a class. But let’s not get ahead of ourselves.

#Bus Infinity Fabric and the speed of internuclear interaction

If we talk about osmeterium and shestiyaderny, the processors Ryzen third generation has retained its traditional basic structure – they are composed of two Quad-core complexes CCX (Core Complex), which are placed in one eight-core processor chip-Deplete CCD (Core Complex Die) and connected inside tire Infinity Fabric. However, the difference from previous processors is that the OCTA core CPU is no longer a single monolithic crystal. The memory controller, PCI Express controller and the SoC elements removed from the CCD chiplet in a separate I/O-chipset manufactured for 12-nm technology at GlobalFoundries companies. This double-crystal arrangement does not affect the communication between cores and L3 cache – everything here stays the same.

In processors with 12 and 16 cores all adds another level of hierarchy – they use the same OCTA core CCD chipley, but a double number. This direct connection with each other CCD chipley do not have. They are connected by bus Infinity Fabric only with I/O-capleton, so all the interaction between nuclei in different chiplet, going through the smart host – I/O chipset.

In the end, it turns out that even in the case of eight cores cores of unequal relative to each other: there is a “close” of the kernel (in one CCX-complex), and is – “distant” (located in different CCX and having the ability to communicate with each other only via Infinity Fabric). In processors based on CCD pair are still “very far” cores physically located in different crystals. For this specific delay when communicating between cores is different depending on, they are United in one CCX or are different. And it is quite disturbing moment: in the processors Ryzen past generations delay encountered when communicating cores from different CCX became quite noticeable and in some cases hindered the performance.

Ryzen in 3000, this issue should have been partially fixed. First, AMD worked with Microsoft and was able to ensure that the scheduler of the operating system now account for the topology of the processor and first loaded the kernel from one CCX-complex, moving to the next CCX, available only when the kernel is already loaded in the previous job. Such a strategy is inherent to the scheduler in the new version of Windows 10 May 2019 Update in relation to the processors Ryzen this allows to reduce the number of calls inter-core bus-Infinity Fabric high delays and focus calculations, if they do not load all the processor cores inside the CPU the smallest unit.

Secondly, the tyre Infinity Fabric Ryzen new generation of markedly accelerated by itself: its width is doubled from 256 to 512 bits. Much it improves the situation? Positive effect it is easy to check that, we did our traditional test delays when transferring data between cores. For comparison, the following are the results of the measurements made, not only for the OCTA-core processor Ryzen third generation, but also for osmeteria last generation (Pinnacle Ridge), and eight Coffee Lake Refresh. All processors during the test was reduced to a single clock frequency of 4.0 GHz, the memory of all CPU operated in the mode DDR4-3466, and that means the tire is Infinity Fabric to compare Ryzen used the same frequency 1733 MHz.

The situation in Ryzen 3000 really has improved markedly. Core belonging to the CCX-complex, is now able to exchange data 25% faster, and the kernel belonging to different CCX are “closer” to each other by a third. Thus, Ryzen 3000, at least if we talk about CPUs with cores not more than eight, problems with high latency inter-core cooperation will be subject to significantly lesser extent. Moreover, the speed of connections between nuclei belonging to the CCX-complex, new members of the family Ryzen has surpassed even Coffee Lake Refresh, which uses a ring bus, which is considered the most successful variant of the connection parts of the processor into a single unit.

The positive impact of high speed Infinity Fabric should be manifested not only when transferring data between cores. It is worth Recalling that each CCX-complex Ryzen processor has its own cache of the third level, and all the large 32 MB L3 cache in eight Ryzen 3000 actually represents two cache to 16 MB. Therefore, treatment using Infinity Fabric occur in the case when the kernel of the same CCX-complex need of data in L3-cache of the second CCX-complex. Therefore, the observed speedup Infinity Fabric should have a positive impact on performance in a wide range of situations, including when working with data.

However, another problem associated with the speed Infinity Fabric remained unresolved: the frequency of this bus continues to be associated with the frequency of the memory controller. Although the new AMD processors and implemented the asynchronous mode of operation Infinity Fabric, the frequency of this bus still can not exceed the frequency at which the memory controller and the DDR4 SDRAM will continue to have a significant impact on the performance of Ryzen 3000.

#Speed cache memory

If we talk about working with the data, then the subsystem of the cache memory in processors Ryzen 3000 has not changed. The cache memory of the first (L1D) and the second level will retain the same size, organisation and latency, and the only novelty is the increased cache of the third level. Due to the transition to the 7-nm technology AMD allowed themselves to significantly increase the transistor budget CCX-complexes, and thus the third level cache has been doubled to 16 MB for every four cores. But even this area, which Ryzen 3000 is a CCX-a set of 7-nm semiconductor crystal is only 31,3 mm2, while in the processors of the previous generation, which are produced at 12-nm technology, CCX-complex is a 60 mm2.

But the increase in L3 cache there was not so much from the generosity of the developers. This is partly a forced measure. The new processors chilenas layout memory controller “drifted away” from the cores, and cache as much data – a method is needed in order to try to reduce the number of situations when processor cores are idle waiting for data from memory. AMD representatives say that in the first place, this should help resolve performance issues in games, but we’ll see.

Now I want to talk about another point: the increase in the volume of the cache memory is always accompanied by an increase in its delay. So what happened this time, but in fairness it should be noted that the increase in latency was quite small, with 38-39 to 41-42 cycles.

In the graphs below, we compared the latency of the cache memory eight cores Ryzen second and third generations, as well as relevant representatives of the family of Intel Core. All processors during the measurement was reduced to a single frequency of 4.0 GHz.

The cache memory of the first and second level Ryzen 3000 in comparison with processors of the previous generation has not changed its key performance parameters. The latency L1 and L2 cache remains at 4 and 12 bars. However, to say that the nearest to the computing cores, the cache memory is not changed, it would be wrong. The first-level cache Ryzen in 3000 is actually faster, because now he is able to serve two 256-bit read and one 256-bit write each cycle, which means increased throughput compared with previous processor family Ryzen in half.

As a result, the speed of L1 and L2 cache Ryzen 3000 are fully comparable with the speed of the cache memory levels lower in the actual mass processors competitor. And the cache memory of the third level in the new Ryzen, though, and increased its latency can still offer lower latency compared to the L3-cache in Intel processors Coffee Lake Refresh. However, we should not lose sight of the fundamentally different algorithms L3 cache in processors from different manufacturers. Zen/Zen+ and Zen 2 cache of the third level is very simple and victimization, and also independent for each CCX-complex. At the same time, consumer Intel platform LGA 1151 implemented more intelligent of inclusive cache, with writeback that is shared between all cores. In other words, the practical efficiency of the L3 cache in AMD and Intel are very different.

However, graphs are given of the latency give some reasons for concern. Namely, the concern is the terminal part of the curve of latency to Matisse, which shows the characteristics of the memory subsystem. As you can see, there are no reasons for optimism: Ryzen third generation were worse than their predecessors and, as a consequence, really lost on memory latency processors competitor. What’s the matter?

#Work with memory

Implemented in Ryzen 3000 Chilena layout was shared between the computing cores and the memory controller. While CCX-complexes with cores and L3 cache are in the 7-nm CCD-chiplet, the memory controller along with a PCI Express controller and elements of the SoC issued in another I/O-chiplet. The connection between chipsetati mounted the processor on a single printed substrate, using tires Infinity Fabric, which means data path from memory to CPU core has an additional stage. Although AMD says that the external bus Infinity Fabric similar high-speed characteristics of the bus that bind CCX-complexes inside the CCD chiplet, all of this somehow had an impact on the delays that occur when accessing the memory.

In other words, when it was discovered that the latency of memory Ryzen 3000 became worse than before, we are not surprised. More interesting: how deteriorated the speed of the memory in the new AMD processors. Clearly the answer to this question indicators Cachemem test from the AIDA64 utility (for correct measurements, all processors have the same frequency of 4.0 GHz in all cases, the systems have dual channel DDR4-3466 SDRAM timings 16-16-16-36-1T).

As shown, worsening memory latency Ryzen in 3000 compared with the previous generation processor is about 11 %. In addition, deteriorated, and the throughput speed of the recording, which shows the memory controller Ryzen 3000, became one and a half times lower than they were before. In other words, miracles do not happen: just as occurred in the mid-2000s, years of moving the memory controller from the chipset into the processor to accelerate work with memory, reverse the separation of the memory controller from cores naturally led to the opposite result.

Moreover, for AMD processors, the increase in memory latency is not just annoying little thing, it is really a very unpleasant moment. Speed of work with memory Ryzen last generation and so much lost to competitor processors. Now, with the release of Ryzen 3000, the situation will only get worse. Although throughput when reading and copying data from Ryzen 3000 and Intel Refresh Coffee Lake remain comparable, the speed of entry and from the point of view of the latency of memory, the new AMD processors are inferior competitors in 1,6-1,8 times.

But not everything is so dramatic. For potential buyers Ryzen third generation there is good news. The most important – in the newer processors used significantly redesigned memory controller, which is not so capricious as its predecessor. This is reflected in the passport characteristics: new Ryzen 3000 has received official support DDR4-3200 SDRAM, which had not formally been proposed. Moreover, the performance of the memory in the mode DDR4-3200 is guaranteed for all pairs of modules, regardless of their organization and the component base.

In addition, if we talk about implemented in a new memory controller capabilities, it is worth mentioning a couple of important things. First, Ryzen 3000 will now be supported by 32 GB modules, which means that in a system based on the new processors can be installed in a total of 128 GB memory. Second, the memory controller supports ECC. However, the ability to use this feature will depend on the motherboard, and, as experience shows, in regular consumer platforms, manufacturers usually do not activate.

However, the main advantages of the new controller becomes clear when its practical use. It is no exaggeration to call it unproblematic: it is omnivorous in respect to the memory modules and much more stable, not requiring tedious selection of timings to achieve stability at a relatively high frequency. At the time, as with processors Ryzen in previous generations the memory modules rarely could run in the modes faster DDR4-3466, with the new controller does not cause the problem and run the memory in higher speed modes. Coupled with the increased volume cache of the third level, this largely offsets the increase in latency of the memory subsystem as a whole.

However, AMD wouldn’t be himself if positive change didn’t come with the list of limitations and reservations. So, despite the possibility of considerable acceleration of memory, the maximum a rational mode of operation of memory Ryzen 3000 supports DDR4-3600. In this case, achieving maximum productivity, a more rapid frequency modes is meaningless from the point of view of performance.

Ryzen 7 3700X c DDR4-3600

Ryzen 7 3700X c DDR4-3600

The reason is that relations between the frequencies of the memory, memory controller and bus Infinity Fabric. They have complicated the lives of fans of AMD before, and will continue to do the same in processors Ryzen 3000, although certain changes have occurred. The most important thing: AMD has been able to decouple the bus frequency Infinity Fabric from the frequency of the memory: they are in the newer processors can vary independently. However, there is an important caveat: frequency Infinity Fabric must be either equal to or lower than the frequency of the memory. This means that the choice of memory modules will continue to have a significant impact on the processor performance in General.

The second caveat concerns the fact that the maximum number Infinity Fabric Ryzen 3000 is 1800 MHz, and at higher values the processor can not function. Also there is a third caveat. It concerns the fact that when using faster memory modules DDR4-3600, the clock generator of the memory controller automatically switches to 2:1, that is, starts to operate at half the frequency.

The memory frequency (mclk) The frequency of the memory controller (uclk) Bus frequency is Infinity Fabric (fclk)
Up to DDR4-3600 To 1800 MHz uclk = mclk fclk = mclk
DDR4-3600 1800 MHz uclk = 1800 MHz fclk = 1800 MHz
After DDR4-3600 Above 1800 MHz uclk = mclk/2 fclk = 1800 MHz

All of this leads to the fact that the use of memory in the faster modes DDR4-3600 no practical sense: when crossing the border into the subsystem memory comprising asynchrony adds additional and very significant delays.

Ryzen 7 3700X c DDR4-3866

Ryzen 7 3700X c DDR4-3866

As you can see by the above screenshot, the latency of the memory in the mode DDR4-3866 is approximately 9 NS is higher than when you select DDR4-3600 with the same settings, timings. To compensate for this increase in delay with a further increase in the frequency of DDR4 SDRAM, if we talk about the usual non-extreme overclocking, almost unreal.

Little hope remains that the frequency at Infinity Fabric in the serial processor under some conditions still to be raised above 1800 MHz, because in theory the motherboard have the appropriate setting with a rich choice of frequency for this bus. In this case, the processor systems Ryzen 3000 can make sense to use and faster than the DDR4-3600 modules.

However, we cross the line in the 1800 MHz to Infinity Fabric failed: select higher values will inevitably lead to complete failure of the test system.

#X570 chipset and compatibility with old boards

Ryzen testing the 3000 we were armed with a platform based on the chipset X570. AMD has prepared this chipset specifically for the release of their processor microarchitecture Zen 2, however, the fee for X570 – dispensable companion to the new Ryzen. Like their predecessors, Ryzen 3000 is compatible with the usual socket Socket AM4, capable of working in boards, as issued during the first and second generation Ryzen.

However, it is not so simple. For the new CPUs in older boards needed their support at the BIOS level, but its implementation is not so smooth for marketing reasons. In fact, Ryzen 3000 will be probably compatible with any Board on the X470 and B450, with all other platforms the situation is at the mercy of motherboard manufacturers. Therefore, support for new processors in any specific motherboards with chipsets X370, B350 A320 and may or may not appear.

The criterion of compatibility is simple: to ensure that she or other fee to work with Ryzen 3000, its BIOS needs to be rebuilt using the libraries AMD AGESA PI Combo_AM4 or later. If the motherboard manufacturer has released an update to the firmware Plata Ryzen 3000 will fit.

However, to use now for testing the new processors the old boards, it would not be a good idea. The fact that the motherboard manufacturers put all the efforts on optimizing the BIOS fresh generation Socket AM4 platform and support Ryzen 3000 to older platforms is implemented by a residual principle. It appears that almost all of the available BIOS updates for old boards are based on the code AGESA version or, and these versions do not disclose performance Ryzen 3000 in full.

For proper operation of the new CPU and achieve maximum performance in the BIOS code needs to be applied library Combo_AM4 AMD AGESA PI, and this condition is currently performed only for a few boards, mostly with the chipset X570. For this reason, the tests were conducted us to the X570 which is due to better optimizations to offer better performance in a pair of Ryzen 3000. However, this situation is temporary: as code updates the BIOS in old motherboards with their performance Ryzen 3000 will have to catch up to the same level, which today provide a fresh platform.

The chipset X570 are no particularly popular in this moment of opportunity in the platform Socket AM4 adds. The main reason why users should pay attention to is the appearance in boards based on PCI Express 4.0. If you use 3000 Ryzen in such fees this interface is supported both graphics PCIe x16 slots and slots M. 2 NVMe drives, but also any other PCIe slots. In addition, charges of new generation usually are equipped with a large number of ports USB 3.1 Gen2: processor and chipset X570 unable to provide up to 12 ports.

Processors Ryzen 3000 have 24 lines PCI Express 4.0. Four lines of that number are utilized to connect to the chipset, and four more lines are given to work with the system NVMe SSD. The remaining 16 lines is an interface with the graphics card.

Chipset X570 has at its disposal 20 PCI Express 4.0, four of which need to communicate with the processor. The remaining 16 lines of the manufacturer of the motherboard may allocate the PCIe, M. 2, or to configure them as additional SATA ports.

At this stage it all seems not so popular, although devices that support PCI Express 4.0 gradually penetrate into the market. So looking interface with twice as high throughput will use the graphics card Radeon 5700 RX and RX 5700XT. In addition, in the near future will begin to appear and SSD based on Phison controller PS5016-E16 (for example, the Gigabyte AORUS Gen4 NVMe SSD or Corsair Force Series MP600) that will also be able to take advantage of the increased bandwidth of the interface.

However, if you are thinking about purchasing motherboards X570, you should keep in mind that this chipset is very hot chip, the dissipation of which lies in the range of 11 to 14 watts under peak loads. Technically it is a reconfigured I/O-chiplet from server processors EPYC Rome, meaning it is based on a 14 nm chip manufactured at the facilities of GlobalFoundries. And so it is not surprising that she, as the processors need active cooling: the vast majority X570-motherboard used chipsety cooler with a fan.

In addition, Socket AM4-boards that use the X570 will be among the flagship platforms. And this means that they will cost a lot to expect that the price of the cheapest boards of the new generation will start from $200-$250.

The range of processors Ryzen 3000 (code name Matisse) consists of six versions: two shestiyaderny, two osmeteria, dvenadtsatietazhnogo and shestnadtsatiyaderny processors. For the first trial review we chose the average model Junior OCTA core CPU Ryzen 7 3700X.

This was done primarily because it is easy to pick up competitors – OCTA core processor as a competitor, and among Ryzen past generations. In addition, Ryzen 7 3700X seems to be one of the most popular new products. It is possible to conclude, if you look at the composition of the lineup completely.

Cores/ Threads Base frequency, MHz Turbo frequency MHz L3 cache MB TDP, watts Chipley Price
Ryzen 9 3950X 16/32 3,5 4,7 64 105 2×CCD + I/O $749
Ryzen 9 3900X 12/24 3,8 4,6 64 105 2×CCD + I/O $499
Ryzen 7 3800X 8/16 3,9 4,5 32 105 CCD + I/O $399
Ryzen 7 3700X 8/16 3,6 4,4 32 65 CCD + I/O $329
Ryzen 5 3600X 6/12 3,8 4,4 32 95 CCD + I/O $249
Ryzen 5 3600 6/12 3,6 4,2 32 65 CCD + I/O $199

The attractiveness of Ryzen 3000 is due to four factors: high performance, affordable price, reasonable power consumption and heat and hope for a non-zero overclocking potential.

And indeed, Ryzen 7 3700X – a full eight-core Socket AM4 processor microarchitecture Zen 2, collected from a single 7-nm CCD-chiplet with a complete set of active cores and 12-nm I/O chiplet. It has a slightly lower frequency in comparison with the older osmeterium Ryzen 7 3800X, however, the difference in maximum frequency is only 100 MHz. No other fundamental differences have Ryzen 7 3700X in stock and a full-sized L3 cache for a total volume of 32 MB, and the L2 cache capacity of 512 KB per core.

That as the base frequency for the CPU is specified at 3.6 GHz, it is possible not to pay attention – in reality due to the technology of Precision avtoradgona Boost 2 CPU almost always comes at a much higher speed. For example, when testing in Cinebench R20 with load for different number of cores our instance showed real frequencies in the range from 4.1 to 4.4 GHz, which not only looks good, but exceeds the typical operating frequencies of last year’s flagship, Ryzen 7 2700X.

However, AMD is clearly disingenuous, speaking of energy efficiency Ryzen 7 3700X and relating it to 65-watt thermal package. To understand this, it helps to see how the system behaves with this CPU in the nominal mode in the stress tests, for example, in Prime95.

Raises questions are literally everything. And we should start with high operating temperature, which for our instance Ryzen 7 3700X test in Prime95 29.8 reached 90 degrees at that the AMD considers to be the maximum possible heating of CPU only to 95 degrees. But this picture in our case, there is not even a boxed Wraith Prism, but with much more powerful Noctua NH-U14S.

Of course, the processor crystal, performed on a 7-nm standards, has a very small “contact patch” with the heat-spreading lid, and therefore, cooling Ryzen 3000 really harder than the 12 – and 14-nm processors. However, the 90-degree heat CPU makes me doubt that this CPU under load shows the energy consumption at 53 W warn about all of its internal sensors. The impression is that AMD deliberately and very much lowers rates of consumption so that the processor is automatically overclocked to a higher frequency in the technology of Precision Boost 2, which for 65-watt Ryzen 7 3700X sets the upper threshold of consumption of 88 watts.

About what the real consumption Ryzen 7 3700X, to let the sensor Converter power the motherboard. According to their testimony, on the processor, which supposedly creates electrical load 53 W, current is supplied with a power of 106 watts plus about 15 watts per SoC. The system as a whole at this time shows consumption of the order of 185-190 watts, so that no doubt remains: 65-watt Ryzen 7 3700X under load can consume about twice the declared thermal package. In other words, energy efficiency Ryzen 7 3700X is a lie, slander and provocation.

Of course, this consumption can be attributed to misconfiguration technology Precision Boost 2 in the BIOS specific motherboard or AMD initiated by the most wilful disregard of the part of the heating package, but you need to understand that if the manufacturer and decide to return Ryzen 7 3700X promised energy efficiency, it will inevitably hurt its performance. Otherwise here is not given.

But then Ryzen 7 3700X not to take, it’s a very attractive price. Ryzen 7 3700X – not just the cheapest cosmedent architecture Zen 2, is also the processor with the lowest in the new model range of the specific value of the kernel. In addition, its cost is lower prices Junior OCTA core proposals of the competitor. All of this could easily be done by Ryzen 7 3700X “choice of millions”, despite any of its shortcomings.


Ryzen 7 3700X – Junior cosmedent in the lineup of new products, and such induction usually means the processor is effective to disperse at least reach the frequency of senior representatives of the model range. Moreover, AMD traditionally did not repair any obstacles overclockers. Multipliers Ryzen in 7 3700X are not blocked and heat-dissipating cover continues to pripiats to the surface of semiconductor crystals, despite the fact that under it their is now two.

However, dispersal is still not about Ryzen 7 3700X. AMD in each new generation has steadily squeezed from the processor frequency potential all the juice, and to date has achieved this perfection. We can say that Ryzen 7 3700X operated close to the limit of their capabilities even in the nominal mode due to the technology of Precision Boost 2, which is clearly implying the observed operating temperatures.

Anyway, the maximum frequency we managed to “squeeze” when manually overclocking Ryzen 7 3700X, was only 4.2 GHz. If you increase the voltage to 1.4 V CPU at this frequency was stable and passed stress tests in Prime95, but temperatures under load increased to 105 degrees, which is hardly a normal operational mode.

The result is of more theoretical value, and to resort to such a crackdown on the practice makes no sense. The performance boost in multi-threaded load will be a few percent despite the fact that at partial load of cores the CPU will work even slower than in the nominal mode.

While AMD offers enthusiasts another way to increase performance – adjustment settings Precision Boost 2 so that the processor yourself out on the higher frequencies as a built-in algorithm avtoradgona. This technology allows you to change the key supporting constant – consumption limits current (PPT) and electric power (TDC and EDC), together with the increase in the upper limit frequency, and can be used for acceleration. However, some noticeable effect by changing these limits in the case of Ryzen 7 3700X us to achieve and failed. Even in the nominal mode Precision Boost 2 controls the frequency Ryzen 7 3700X very aggressive, and the main problem standing in the way of dispersal is not limiting, consumption and currents, and high temperatures.

Overview motherboard ASUS ROG Crosshair Formula VIII: Formula for first Ryzen

Code: JJRC88. Coupon code is required. Limited on time and amount of items.

Not so long ago on our website an overview of the Gigabyte Aorus X570 Xtreme first fell into our hands motherboard for Socket AM4-of CPU cycles, which cost about $ 700. However, as it turned out, this is not the only product of its kind. The developers of motherboards so inspired by the emergence of third-generation processors Ryzen that, not saying a word, significantly raised the upper limit of the price of the platforms, which are based on a new chipset X570. The result of the $ 700 fee under the mass of the AMD is now in the range of almost every self-respecting manufacturer of the motherboard. And as if confirming this thesis, followed by premium Gigabyte in the laboratory 3DNews arrived ASUS ROG Crosshair Formula VIII is another flagship platform with the price of the same scale.

Immediately it should be noted that stuffed heartily Socket AM4 Plata in the representation of developers of ASUS looks quite different from how it is represented in Gigabyte. In other words, the top-level products from different manufacturers turned out to be quite dissimilar. ASUS ROG Crosshair Formula VIII loses a bit of its facilities and not so perfect in layout and design, but in her arms there are other cards. ASUS has added to its flagship product the possibility to include it in the circuit liquid cooling system out of the box, worked hard on the BIOS and season it all with a cocktail of several proprietary technologies that improve system stability when overclocking. The result was a very interesting product that is sure to attract the attention of enthusiasts and it undoubtedly deserves a detailed review.

Besides the ROG Crosshair Formula VIII and is interesting for another reason. This is the first motherboard Formula class among the solutions ASUS for processors Ryzen. In the hierarchy ROG products, the names of which incorporated the epithet Formula, differ in two specific features. First, their cooling system is being developed in collaboration with specialists from EK Water Blocks and has an integrated water block. Second, they carry a special aesthetic in their design used “armour”, almost completely hiding the entire front surface of the Board.

Until today, ASUS believed that to release such hardware for the platform Socket AM4 is meaningless, because the owners Ryzen is an unpretentious audience that will not appreciate these design refinements. But now the situation has changed, because among processors, AMD introduced the high-level proposals that can compete not only with the Core i9-9900K, but also with the decisions of the class HEDT. It is obvious that the enthusiasts who liked processors like Ryzen 3800X 7 or 9 Ryzen 3900X, and focuses the ASUS: ROG Crosshair Formula VIII will be a solid frame for these “stones”.

However, there is a suspicion that the ROG Crosshair Formula VIII is not the maximum scenario gaming platform ASUS, which will eventually be available in the model range of products of this manufacturer on the basis of a set of logic X570. Although we haven’t heard anything about VIII Crosshair Extreme, this motherboard will likely also be released, but it will happen a little later, when the market will come uncompromising 16-core Ryzen 9 3950X.

But while the “extreme” Board is in sight, lets look at ASUS ROG Crosshair Formula VIII is the best option platform ASUS for AMD Ryzen today.


At the moment we know about the existence of the family ROG Crosshair VIII, based on the new AMD Radeon X570, four models of motherboards. In addition to the flagship 700-dollar Formula company ASUS intends to soon bring to market a Mini-ITX platform Impact, and two full-sized tab – Hero (Wi-Fi) and the Hero is already available in stores. In this case it so happened that the recommended price is closest to the Formula for the positioning of the Hero (Wi-Fi) is only $380, but the characteristics it is very similar to her. Yes, the design of Hero (Wi-Fi) cannot accommodate two-way reservation and the possibility of liquid cooling the VRM, but the majority of consumer properties, including construction of the Converter of CPU power, it is not inferior to the older sister. Hence the conclusion: ROG Crosshair Formula VIII – frankly the premium offer, the high cost which is largely determined by not so much technical “bells and whistles” as status and elitism. However, it makes acquaintance with the ROG Crosshair Formula VIII is even more interesting.

Here are the basic specifications such expensive fees:

In a perfect world, motherboard with max price should offer the maximum of opportunity. However, some features ROG Crosshair Formula VIII, as it turns out, but max has not been completed. And this means that among the AM4 Socket boards, you can find products are equipped with richer. One of the examples is not necessary. The flagship ROG Board is equipped with only two slots M. 2, and has a 10 Gigabit network controller, having these parameters, the alternatives from other manufacturers. It is therefore very likely that ASUS really soon offer an even more powerful card Extreme class. This should happen at least for the sake of all fell into place.

However, it would be unfair to say that the possibility of ASUS ROG Crosshair Formula VIII is insufficient. This fee will be an excellent Foundation for high-performance computer based on older processors Ryzen 3000. Moreover, the system with this Board and CPU like 9 or 3900X Ryzen Ryzen 9 3950X may be able to compete in terms of equipment and performance of a real workstation class HEDT. Lose platform based on an ASUS ROG Crosshair Formula VIII only the number of memory channels and the number of supported PCIe devices. But here is affected by restrictions processors Ryzen 3000, besides huge amounts of memory and multi-component arrays of graphics cards and NVMe drives are used not so often.

Speaking about the characteristics of ASUS ROG Crosshair Formula VIII, it is impossible to ignore and one more important point: this Board is well suited to systems that use custom liquid cooling. The fact that a regular complete, it can be included in the LC loop due to the special design of the VRM cooling system, which was developed with the participation of the engineers of the company EK Water Blocks. Socket AM4-boards that are compatible with liquid cooling right out of the box, the phenomenon is not unique, however, not so much, and every such an example deserves special mention.

#Packaging equipment

ASUS ROG Crosshair Formula VIII comes in a large colorful box decorated in the standard series motherboards ROG style. On the upper surface of the package is the name of the prisoner inside the product. The reverse side contains a picture card with the description of the main characteristics and technologies.


ASUS marketing Department thought it necessary to draw the attention of the potential buyer on a strong power system ROG Crosshair Formula VIII, the scan OLED display LiveDash, to support the cost of Wi-Fi and 6 wired network with throughput up to 5 Gbps, and CrossChill III EK – waterblock special design for heat dissipation from the power supply circuit of the processor.

The supplied ROG Crosshair Formula VIII is quite standard — given the fact that this Board refers to the upper price range. In addition to the actual motherboard and a large volume of printing products in the box fit:

  • six SATA cables;
  • one cable to connect addressable led strips;
  • one connection cable for led RGB strips;
  • one of the two-component dual-band Wi-Fi antenna;
  • module Q-Connector for easy connection LEDs, and buttons of the housing;
  • set of screws for mounting the M. 2 drives.

It is worth to pay attention to a few things. First, two of the six SATA cables that came with the Board, have woven braid that gives this simple accessory a more noble appearance.

Second, ASUS has replaced two required for modern Wi-Fi adapters antenna one working in the mode of 2 × 2. In addition, the manufacturer never declared by its gain factor.

It should be noted that the necessary drivers and software to motherboard ASUS continues to put on a CD-ROM, which frankly, in modern conditions seems somehow anachronistic. However, if your system will be optical device to come to the aid of technology Armoury Crate which allows you to automatically download and install software over the Internet. It works in Windows 8 and 10 using the function of the Windows Platform Binary Table that performs automatic backup of UEFI and the startup after loading a pre-trained manufacturer service utilities.

Equipment fees after experience leaves a feeling of light disappointment in their flagship Board, ASUS has been generous even for external temperature sensors. A set of supplied cables to connect the RGB ribbons on the composition equal to that placed in the boxes of their boards by other manufacturers.

#Design and capabilities

The first thing that catches the eye when removing your ASUS ROG Crosshair Formula VIII out of the box is its size. Manufacturers have accustomed us to the fact that if the Board refers to the upper price segment, it must have an increased size E-ATX. But ROG Crosshair Formula VIII, by contrast, made more widespread and more compact standard form factor ATX, which significantly expands many of the buildings in which it can comfortably be located.

However, because of this, ROG Crosshair Formula VIII has amassed a number of problems associated with the inability to place all of the many components on its surface so that they were really convenient to use. In the process of testing revealed two rather unpleasant moment.

The first is an acute lack of space around the CPU socket. The first slot is PCIe x16 for Socket AM4 is so close that the tower coolers, designed for 140mm fans, get up on it with some problems. If the graphics card is equipped with a rear plate, even not too large thickness, between it and the edge of the radiator, the cooler remains very narrow gap in which are placed bad (frankly, do not fit) the mounting bracket of the fan. And that means ROG Crosshair Formula VIII is much more comfortable to use with liquid cooling systems than air supernumerary.

The second point concerns the placement of the last PCIe x16 slot is directly at the bottom edge of the Board. The problem with this arrangement is that installation of any expansion card will lead to the overlap of the access located on the bottom edge controls, including popular buttons Safe Boot and Retry Button.

All this is clearly seen in the conceptual graphic of the Board. Even it perfectly clear that all significant components “moved out” of the plane of the PCB down.

But the main question for ASUS ROG Crosshair Formula VIII concerns the placement of the slots and controls, and cooling. The fact that in the whole lineup based on the X570 motherboard ASUS engineers decided to use separate cooling for the chipset and VRM. The chipset is always cooled by the air cooler. The same scheme is implemented in ROG Crosshair Formula VIII. That is, despite the fact that this Board is supposed liquid cooled VRM, heat from the chipset in any case will still be given air. And what a strange and irrational decision.

Cooling the chipset cooler also raises certain questions related to its design. It is a fairly massive aluminum radiator with edges directed to the rear side of the Board. The fan drives the airflow along the edges, while the exhaust air is discharged to the rear of the PCIe slots through a slit in the cover that protects the surface of the Board.

While ASUS and assures that the Board uses a Delta fan with ball bearings for up to seven years of continuous operation, you need to understand that we are talking about a centrifugal fan with a diameter of 40 mm and the ability to develop a sufficiently high speed. Although in normal condition it rotates with a frequency of about 2500 rpm at which the noise level is minimal, its speed when increasing temperature markedly increases. A negative role here can play what air intake chipsety cooler carries the right of the first PCIe x16 slot, that is where a graphics card emit hot air from their cooling systems.

In our test system we used the GeForce RTX 2080 Ti Founders Edition, and run it, for example, the “donut” Furmark even outdoor stand led to an increase in the temperature of the chipset to 75 degrees and dispersal chipsetov fan to 3800 RPM at which the noise became clearly visible.

In other words, from a flagship motherboard, we expected more elaborate cooling.

But in regard to cooling Converter power ROG Crosshair Formula VIII, the engineers, by contrast, did a great job.


The cooling system is a single massive l-shaped aluminum waterblock with a copper core, which, because of its size, can operate in and in the passive mode as an ordinary radiator.


He firmly held on the power Board elements with powerful screw mount, and in addition, the VRM area is cooled and the back side of the Board. The bottom surface of the circuit Board is covered with galvanized steel plate, which not only protects it from damage, but also takes heat from under Converter supply.

Although ASUS says that the ROG connect Crosshair Formula VIII to the circuit liquid cooling, the temperature of the VRM can be reduced to a 29 degree, to survive because of the high temperature of the power circuit will not have even if the cooling of the power Converter will work as is in passive mode.

The fact that poorly heated itself this scheme: it is collected on high-performance elements, which have relatively low heat dissipation. The maximum temperature of the Converter of CPU power, which we managed to capture during overclocking tests with air cooling the VRM was only 55 degrees. And this is logical: the heat dissipation of each of the 16 power stage Infineon PowIRstage IR3555 on the basis of which assembled power circuit currents at the required senior Ryzen 3000, even acceleration does not exceed 1.0 to 1.5 watts.

It is curious that, despite the use of the VRM 16 sets of the power stage, solid state capacitors and chokes MicroFine Alloy, the entire design is driven by OCTA-core PWM controller ASP 1405I (Infineon IR35201). This means that “good” channels in the Converter power only eight – seven on the CPU and one to SoC. Twice the number of elements used for their superalliance in the channels, allowing the power Converter to handle higher loads. However, you need to understand that VRM is clearly excessive: the maximum output can reach 900 watts, which is not able to consume none of the processors Ryzen 3000, even in the incredible acceleration.

In General, the projected ROG Crosshair Formula VIII with a clear eye on overclockers and enthusiasts. And colossal power VRM is not the only outstanding is a sign. Card comes with a set of handy hardware buttons, including brand Safe_Boot and Retry_Button, and the usual Reset button you can even reassign functions, for example, are able to switch the RGB illumination or by means of BIOS (DirectKey). Close to all key units of the Board are led indicators Q-Led, with which you can quickly diagnose problems. In addition, the Board is fully equipped located in the center of the rear ports OLED screen LiveDash that when you start the system replaces the indicator POST-codes, and then can display selected features hardware monitoring or just a random custom animation.

However, perhaps the main advantage of the ROG Crosshair Formula VIII is, as implemented on this motherboard DIMM slots. For them, the Diasy Chain topology, which allows to achieve the best overclocking results when using a pair of modules DDR4 SDRAM, and the food memory is more powerful than most other cards, the two-phase scheme. This, together with the optimized trace tracks ASUS calls the technology OptiMem III, promising that the ROG Crosshair Formula VIII will achieve in overclocking memory the best results. This is reflected in BOMs: the promised possibility of a stable operation mode memory DDR4-4800, however, this is recommended only one specific variety modules – recently announced Corsair Vengeance LPX CMK16GX4M2Z4800C18 ver3.3.

In addition, a lot of attention in the design of the ROG Crosshair Formula VIII is given to the hardware monitoring. Board is able to monitor the temperature of CPU, chipset and VRM design, and also has a connector for the external sensor. There are four points to connect the case fans. For CPU cooling system, there are two special fan connectors, and some connector to enable the pump factory SVO. If the user wants to collect the liquid cooling alone, in which case the fee will be able to provide connectors to enable the temperature sensors, and fluid flow as well as a dedicated slot to power the pump is consuming current up to 3 A.

In the construction ROG Crosshair Formula VIII, there are three full-size PCIe x16 and one PCIe x1. Two PCIe x16 slot connected to the processor and can work in either x16/x0 or as x8/x8, while the last PCIe x16 slot is connected to only four PCI Express 4.0 chipset.

The first PCIe x16 slot much removed from the rest, so the video card installed in him, would feel quite at ease, even if it is to have a massive cooling system.

But with the placement of the M. 2 slots the developers of ASUS made an experiment, the results of which can hardly be called positive. First, the ROG Crosshair Formula VIII can be only two M. 2-drive — add to the Board the third slot engineers felt unnecessary. Second, both M. 2 slot for one CPU and another chipset is under the second PCIe x16 slot and located in a special compartment “towards each other”. This imposes certain restrictions on the size of M. 2 storage devices, allowing to charge a few M. 2 SSD only if they have the format 2280 or less.

In this storage compartment is closed with aluminum lid, concurrently playing the role of a means of cooling the SSD, but this cover is with the chipset not reported and transfers the heat only by its own heat-dissipating capabilities.

The lack of reporting on the Board of the third M. 2 slot kompensiruet increased number of SATA ports on the ROG Crosshair Formula VIII, as many as eight pieces. They all work using the X570 chipset, so ASUS should be interesting to fans of multicomponent RAID.

In addition to the SATA ports the Board has an internal USB port connector 3.2 Gen2 connector and two USB ports 3.2 Gen1.

Pleased with the abundance of connectors and the rear panel Board. Number of external USB ports brought to 12, among them – one USB port 3.2 Gen2 Type-C, seven USB ports 3.2 Gen2 Type-A and four USB ports 3.2 Gen1. In addition to the rear panel derived two wired network ports for Gigabit and 5-Gigabit connectivity and two ports for wifi antennas. There are five analog audio and optical S/P-DIF. Also there are two buttons – Clear CMOS and BIOS Flashback.

The list of external ports of the Board draws attention to its advanced networking options. In addition to the usual Gigabit Intel i211-at, at ROG Crosshair Formula VIII there is another network controller – Aquantia AQtion AQC111C support Gigabit, and 2.5 – or 5-Gigabit connection. Naturally, higher speeds require the support of the corresponding functionality from the network infrastructure, and this is probably why the developers did not put on the ROG Crosshair Formula VIII 10 Gigabit controller, although the flagship boards from other manufacturers are often equipped with more powerful network chips Aquantia AQtion AQC107.

As for the wireless network, for her work meets the latest module Intel Wi-Fi 6 AX200. It is compatible with the IEEE 802.11 ax and configuration 2T2R capable of providing data transmission speeds to 2.4 GB/s. Also in the module AX200 supported standard Bluetooth 5.

Sound system under consideration motherboard ASUS uses a 10-channel codec Realtek SupremeFX S1220 ratio “signal — noise” dB 113 in combination with the discrete ESS ES9023P DAC and operational amplifier Texas Instruments RC4580. Naturally, the engineers have not forgotten to isolate the audio circuit from the rest of the Board and cast a high-quality Japanese Nichicon capacitors.

However, summing up all said, we have to admit that their opportunities ROG Crosshair Formula VIII is still not amazing. Board on the basis of the X570 premium level, which offered other producers in certain properties may look better than the ASUS. But what is ROG Crosshair Formula VIII definitely spit all the alternatives, so it is in appearance.

Simply aligning the cut lines and monochrome colors with mirrored panels inside which are hidden RGB-backlight, ASUS was able to ensure that the Board does not look pretentious, but on the contrary, is perceived as a high-tech and utilitarian, but at the same time elegant device.

AMD 3800X Ryzen 7: champion heating

Output processors Ryzen, built on microarchitecture Zen 2, made a splash: at the third attempt AMD managed to make consumer CPUs, which look a worthy competitor to Intel Core, not in some specific scenarios, but in General. Yes, AMD was not able yet to eliminate all bottlenecks, microarchitecture, and fresh processors are not as productive in games as current offers Intel. But the gap is steadily shrinking, and now it is quite possible to close the eyes, because in many situations, it kompensiruet tremendous advantage Ryzen 3000 in resource-intensive computing tasks.

However, there is one important caveat: the model number that is generated from fresh processor microarchitecture Zen 2, is more successful, and less successful models. To date, we managed to get acquainted in detail with most members of the series Ryzen 3000 – surveys available on our website at:

Summing up everything written in these articles, we can say that the best impression among all members of the third generation Ryzen Ryzen produces 3600 5 is the most affordable six-core processor, which in some cases is able to compete with Core i5-9400 and Core i5-9600K even gaming load, and the task of creating content up to the Core i7. Also very interesting Ryzen 9 3900X, but it is attractive mainly for its stunning computing power provide twelve cores support SMT technology. In fact, this massive Socket AM4-processor could take a seat available alternatives suggestions class HEDT: it can be supplied in workstation and it will not compromise, but a decent system for high loads.

Same OCTA core Ryzen 3000 in the background Ryzen Ryzen 5 3600 9 3900X don’t seem to be charismatic heroes. We had the opportunity to learn about Ryzen 7 3700X, and it was a good processor, showing the data-intensive applications, the performance of Core i7-9900K. However, from the CPU of this level would like to and excellent gaming performance, and that he could not boast. The frame rate in games Ryzen 3700X 7 lags behind even the Core i7-9700K, and the amount of lag sometimes comes to 10-15 %.

However, it is possible that claims to gaming performance arose from the fact that we tested is not the best option OCTA core Ryzen. For some reason AMD decided to send the press not 7 3800X senior Ryzen, Ryzen and the youngest 7 3700X, which has a more strict TDP and lower clock frequency. To limit the gaming performance could this, therefore, before drawing final conclusions about the practical value of new products OCTA core AMD, should be detailed to test and the older model with eight cores. And we did it: in today’s review we will share the results of the tests Ryzen 7 3800X – processor, which compared Ryzen 7 3700X 300 MHz higher clock frequency and 60% higher than the calculated heat.

#7 3800X Ryzen in detail

If you are interested to see what is inside 7 3800X Ryzen in all technical details, you can refer to the review Ryzen 3700X 7: in design and architecture, these processors are absolutely identical. As a Junior cosmedent, Ryzen 7 3800X assembled on the basis of two chipsetov connected between a proprietary bus Fabric Infinity second generation. One of them is OCTA core crystal CCD, consists of two Quad-core modules CCX. The second crystal cIOD responsible for the functions of input / output, containing the memory controller, bus controller, PCI Express 4.0, as well as elements of SoC.

Chipley, which are assembled Ryzen 7 3800X, in the form of standard building blocks, which can be found in any of the processors Ryzen 3000. CCD-chiplet with the nuclei produced via the 7-nm FinFET technology for enterprises TSMC, and he (or they, if we are talking about multi-core solution) are used in any of the AMD CPU microarchitecture Zen 2, whether a mass or a server chip. Chipset I / o issued for 12-nm technology by GlobalFoundries and is found only in the composition of Ryzen 3000. This unification of the constituent parts determines the similarity between any Socket AM4 processors on a wide range of basic characteristics.

Cores/ Threads Base frequency, MHz Turbo frequency MHz L3 cache MB TDP, watts Chipley Price
Ryzen 9 3950X 16/32 3,5 4,7 64 105 2×CCD + I/O $749
Ryzen 9 3900X 12/24 3,8 4,6 64 105 2×CCD + I/O $499
Ryzen 7 3800X 8/16 3,9 4,5 32 105 CCD + I/O $399
Ryzen 7 3700X 8/16 3,6 4,4 32 65 CCD + I/O $329
Ryzen 5 3600X 6/12 3,8 4,4 32 95 CCD + I/O $249
Ryzen 5 3600 6/12 3,6 4,2 32 65 CCD + I/O $199

Ryzen 7 3800X, like other members of the lineup Matisse, built of two chipsetov for different purposes, has a cache memory of the third level capacity of 32 MB, has a memory controller with official support for DDR4-3200 and informal possibilities of using faster modes, and offers support for PCI Express 4.0, which can be useful for productive GPU or NVMe SSDS a new generation. The differences Ryzen 7 3800X other Ryzen 3000 should be sought only in the number of cores or frequency and thermal characteristics.

If you compare Ryzen Ryzen 7 3800X and 7 3700X two OCTA-core CPU, the conclusion is that the older model is similar to the younger one exception: its frequency formula is not limited to artificially clamped within a heat pack. In other words, while Ryzen 7 3700X – cosmedent, which gives priority to efficiency, then Ryzen 7 3800X other priorities – here the emphasis is on absolute performance.

This are caused by such striking differences in TDP. If Ryzen 7 3700X value TDP is set at 65 W and a maximum consumption limit is limited to 88 watts, heat package Ryzen 7 3800X expanded to 105 watts, and the maximum consumption can reach 142 watts. Thus, energy and thermal characteristics of the AMD formally equalized with 7 3800X Ryzen Ryzen dvenadtsatietazhnom 9 3900X collected from three chipsetov. And this, essentially, means that the limits for the consumption and heat generation practically does not hinder the performance Ryzen 7 3800X. Technology Precision Boost 2.0 in this case has the opportunity almost to look back on the PPT option (Package Power Tracking) – observe the current consumption of the processor, and to output the CPU at maximum frequency, limited only by the temperature capabilities of silicon.

However, this still does not allow Ryzen 7 3800X achieve some particularly impressive peaks. Unfortunately, the performance of new generation processors, despite the progressive 7-nanometer production technology, the record for the frequencies can’t be — such are the limitations of microarchitecture and process technology. To work in turbo mode at a frequency higher than 4.5 GHz can’t even free from the limits of consumption and heat dissipation Ryzen 7 3800X and it’s only 100 MHz above turbocast 65-watt Ryzen 7 3700X. One could argue that the base frequency of fosmidomycin differentiating between stronger – by as much as 300 MHz. But in reality it means little: to passport the nominal frequencies of the processors do not work almost never.

In order to show clearly how the situation looks with real frequencies Ryzen 7 3800X, we carried out a standard experiment and checked at what frequency this CPU will work in Cinebench R20 load on different number of cores and threads. On the chart below along with the curve of the average frequency Ryzen 7 3800X provides a similar curve for Ryzen 7 3700X – such a comparison should help to understand how seriously the performance of the two osmeteria may vary with the actual load. For cooling both processors used the same cooler Noctua NH-D15S.

The results can be called even somewhat paradoxical. Judge for yourself: the difference in price Ryzen Ryzen 7 3800X and 7 3700X is $70, but the real frequency of these processors differ by 50-75 MHz, that is, not more than 2-3 %. The picture that is largely similar to the situation with shestidennomu: 2 % extra performance, AMD has to pay extra to the price Ryzen 7 3700X almost 20 % of the cost. Moreover, if in the case of shestiyaderny price for Ryzen 5 3600X yet somehow could be justified bundled with it a more efficient cooler, then Ryzen 7 3800X this argument is not valid. Senior eight-core, like its little brother, the Wraith comes with Prism RGB Cooler Master.

Incidentally, that brings up another discrepancy: cooler Wraith Prism RGB specification is designed to dissipate up to 124 watts of heat, while Ryzen 7 3800X can consume up to 142 watts of electricity. It turns out that the power of the Wraith Prism RGB to cool senior osmeteria may not be enough, and then complete the cooler should be replaced, otherwise you may face a situation where the processor will overheat and drop the frequency because of insufficient cooling.

And this is not some kind of hypothetical situation: Ryzen 7 3800X – a really hot processor. For example, running a stress test like Prime95 29.8 when the system is in par with the use of regular Wraith Prism RGB outdoor bench immediately brought the CPU temperature up to a critical point of 95 degrees, and it’s really led to a decrease in its operating frequency to 4.0 GHz and even lower.

In other words, the question of proper cooling Ryzen 7 3800X should be approached with the utmost seriousness, and cooler for him to pick up poeffektivnee, otherwise the performance is not fully revealed. For example, after the change of the Wraith Prism RGB Noctua NH-D15S minimum frequency Ryzen 7 3800X in the stress test Prime95 29.8 increased up to 4.1 GHz, and while the temperature was kept at around 90 degrees.

It is important to note also that insufficiently productive cooler can affect the frequency Ryzen 7 3800X not only under stress loads. In fact, Wraith Prism RGB limits the ability of this processor in all conditions. This conclusion can be reinforced by observing the frequency in Cinebench R20 load on different number of cores and threads, which we performed with three different cooling systems: complete cooler Wraith Prism RGB, productive two-piece tower Noctua NH-D15S and liquid cooling system NZXT Kraken X72.

The conclusion is obvious: for Ryzen 7 3800X really require a powerful cooling system, otherwise the CPU will not be able to reach their potential and will operate at reduced frequencies, which is what happens with the standard cooler Wraith Prism RGB.

High temperature operation of processors Ryzen 3000 – a fact known and accepted. The reasons include the use of high voltages, with a small square of 7-nm eight-core crystal CCD, making it difficult to effectively eat the allocated heat. So if you for some reason are not satisfied with the high heat, you should try undervolting – reduction of voltage below the nominal voltage.

Despite the fact that Ryzen 7 3800X is a senior and shestnadtsatiletnij OCTA-core processor, AMD positions it as an alternative flagship osmeteria competitor, Core i9-9900K. The official cost Ryzen 7 3800X set to $399, making it a rival to the Core i7-9700K, that is, for the more affordable Intel processor that has eight cores, but does not support Hyper-Threading. Such a contrast allows AMD to offer in the relevant price categories: more developed multithreading that this company has already become a matter of principle. But in addition, AMD compensates for the lower clock frequency of their CPU, because fosmidomycin competitor under load on all cores is able to keep the frequency of 4.6-4.7 GHz, while Ryzen 7 3800X under full load rolls up to 4.1 GHz, that would neither have been written in the specifications.

Of course, to oppose numerical characteristics Ryzen AMD 3000 and Intel Core processor very carefully, because they are based on completely different microarchitectures. Especially now, because AMD has updated the microarchitecture and managed to achieve a Zen 2 a 15 percent increase in IPC (the number of executable per clock cycle instructions), which made the relationship between the performance of AMD and Intel processors, given the same clock frequency, quite heterogeneous. But what definitely surpass 3000 Ryzen solutions of competitor in addition to the number of threads running concurrently is the size of the cache memory and support faster versions of the PCI Express interface. These advantages will certainly give AMD a head start of some subset of the practical problems, and over time the number of such tasks will only grow.


If we are talking about series processors Ryzen 3000, section about overclocking, perhaps, should be abolished. New Ryzen is almost prashantame processors, of which the manufacturer is squeezed all you can, its technology, Precision Boost 2.0. As shown, the introduction of 7-nm semiconductor standards, little has given to the frequency of the potential: so far, none of the tested instances Ryzen 3000 could not provide stable performance in multi-threaded AVX2-load at least at a frequency of 4.3 GHz.

But Ryzen 7 3800X we still waited a few more. And with good reason: for the production of these processors are crystals that AMD are unable to attach email in 7 3700X Ryzen, Ryzen no 9 3900X because of their higher than necessary energy consumption. This means that, most likely, Ryzen 7 3800X gets silicon with high leakage currents, which typically require elevated supply voltages. And such crystals, as a rule, it is better to take the higher frequencies, which, however, simultaneously accompanied by a significant increase in heat dissipation. But with heating, if the acceleration depends on the speed limit of the switching transistors, at least try to cope by applying more powerful cooling systems.

However, despite all the prerequisites, in practice Ryzen 3800X 7 was only slightly more overclockable processor than Ryzen 7 3700X and other members of the family. High, which we managed to achieve, is to work at a frequency of 4.3 GHz at a voltage of 1,275 V. system Performance in this mode was confirmed by passing the test SmallFFT enabled AVX2 instructions in Prime95 29.8, more strong acceleration led to overheating and instability.

But even such a relatively fast overclocking was accompanied by a frightening temperatures of the CPU during Prime95 they went over the 100-degree mark that is hardly an acceptable thermal regime. But most importantly, this heat was very difficult to oppose anything that even flagship cooler Noctua NH-D15S could not cool the ardor of dispersed Ryzen 7 3800X. And it’s clearly not a powerful enough cooling: the cooler is among the best and is able to handle CPUs with a heat pack up to 250 W, while the TDP Ryzen 7 3800X – only 105 watts.

Directly indicates the root of the problem is the fact that while the CPU sensor shows the CPU crystal heating to 100 degrees, the cooler radiator was practically cold: its temperature does not exceed 35-40 degrees. This means that the heat generated by the CPU simply does not reach the cooling system. The bottleneck in the heat transfer is early. It is obvious that the heat flux density generated by the 7-nm capleton CCD can not handle the internal thermal interface, located under the CPU cover, although it is revered by enthusiasts bestlady solder. But nothing strange in the fact that before the solder had no complaints, and now they arose, actually no. Suffice it to recall that the eight-square crystal Ryzen 3000 is only 74 mm2, while, for example, a 12-nm eight-core crystal Ryzen last generation was larger than the 2.9 times.

Acceleration Ryzen 3800X 7 to 4.3 GHz, and even with a frightening heat – not a very encouraging result. In normal condition this processor comes itself at a higher frequency, even when the load on a limited number of cores. So for 24/7 overclocking to manual fixed frequency use is not too appropriate. Instead, it is better to use the Precision Boost Override, which in the case Ryzen 7 3800X makes it not homeopathic, but to the naked eye the effect.

The increase to the maximum limits PPT Limit, Limit and TDC Limit EDC, which Ryzen 7 3800X defaults to 142 W, 95 A and 140 A, respectively, while the 200-megagertsevym increase limit frequency by configuring the Max CPU Boost Clock Override leads to the fact that real working CPU frequency increase around 100 MHz.

But we should not forget that such a result is possible only if the temperature of the CPU are in the “safe zone”. So for overclocking by changing the limits of Precision Boost 2.0 must be installed sufficiently powerful cooler. You should not rely on the possibility of an additional increase in performance when using a standard cooling unit Wraith Prism.

In our experiments we used the super-cooler Noctua NH-D15S, and the following schedule shows in detail, exactly as in the normal cooling function of the Precision Boost Override shifts up the frequency curve at a load of different intensity generated by a test render Cinebench R20.

The minimum frequency of the processor at full load on all cores is increased to 4.2 GHz, while low-flow load Ryzen 7 3800X is able to reach the frequency of 4.4-4.5 GHz. However, you need to understand that productivity gains from such changes in frequency formula will still be very weak, because in relative terms, the frequency increases only 2.0-2.5 %. And this again brings us to the conclusion that overclocking experiments with Ryzen 3000 almost meaningless: significantly accelerate the processor will not work by any means.

When AMD released the first generation processors Ryzen, motherboard with CPU Socket Socket AM4 was a relatively simple and inexpensive products. They clearly lost on equipment platforms that have been proposed for Intel, and even the flagship Socket AM4 solutions cost considerably less advanced circuit boards for the mass processors of the Core family. It was obvious that on the first motherboard manufacturers to seriously doubt the demand for Ryzen and did not expect that the expensive and feature-rich platform for such CPU can really be anyone.

However, over the past two years, AMD has been able to prove that its chips microarchitecture Zen Zen+ Zen 2 and able not just to play in the same weight category as the Intel, and in some situations can definitely be the best offer. For example, the latest dwenadzatiperstnuu Ryzen 9 3900X provides maximum to date, the computational performance among all the mass of the CPU, and a proprietary Ryzen 5 3600 rightfully claims to be the most rational choice in the medium segment. So it is no surprise that the market for Socket AM4-motherboard to date has changed dramatically.

Motherboard Gigabyte Aorus X570 Xtreme, which will be discussed in this article, just acts as a striking illustration of the changes. The fact that it is a flagship platform, equipment which are the envy of many LGA1151v2-Board upper price range. It can boast of extraordinary appearance, thought-out cooling all the heating parts, a very powerful Converter power supply, convenient diagnostic tools, quality integrated sound, a large number of USB 3.2 ports, PCI Express 4.0, a built-in 10-Gigabit network controller, Wi-Fi-enabled 6 and a host of other features advanced level. Honestly, when you take this charge in hand, one might feel that this is no ordinary Socket AM4-Board and full-bodied product-level HEDT.

Actually, on this hint, and price. Gigabyte Aorus X570 Xtreme costs $700, and it was unthinkable that the charge under mass AMD can pull the same amount. But it is not the daring experiment of developers of Gigabyte. Similar in value Socket AM4 Board on the basis of a set of logic X570 offer other manufacturers that unequivocally indicates an existing on these platforms demand. And it is highly symptomatic that boards for Intel LGA1151v2 to $ 700 planks to grow and failed. That is, in the opinion of the Board, in the most powerful platforms today require those buyers who rely on Ryzen, not Intel Core.

What will be those users that decide to spend money on Gigabyte Aorus X570 Xtreme? This is what we will discuss in this review. But her most surprising trait is to say: the Gigabyte has the courage to do X570 on the basis of this charge, which by some miracle without active cooling of the chipset. This is one of the main intrigue of today’s test, because other X570-plat without chipsetov fan at the moment does not exist.


Taking into account the cost of Gigabyte Aorus X570 Xtreme it is not surprising that the characteristics of this Board are wound to the maximum. Everything you could wish for, on this Board there are (almost without exception). Frustrating can perhaps just the inability to connect to the motherboard expansion card with Thunderbolt ports, and the absence in her of any outputs. However, both the functions that in practice are very rarely needed, and the fee for $700 without them is flawed not think.

In the rest of the extensive features of the Gigabyte Aorus X570 Xtreme can be estimated from the following table.

Gigabyte Aorus X570 Xtreme demonstrates the broad capabilities can have a combination of CPU Ryzen 3000 and a set of logic X570. We have already said that this Board is like a platform for HEDT systems, and its passport characteristics once again forced to think about this comparison. Unlike Threadripper Ryzen Ryzen older processors 3000 offer not so many lines of PCI Express to connect the array of graphics cards and have only dual-channel memory controller. But despite this, on the basis of the X570 Aorus Xtreme you can assemble a powerful system that may be used in the role of a high-performance workstation. Especially since the market will be 16-core processors Ryzen 9 3950X.

We should also mention that all of the many Gigabyte Aorus Xtreme X570 implemented it so that the cost was really convenient to use. To do this, the engineers applied a number of non-standard layout solutions, which we’ll talk further. Here, at the stage of exploring the technical characteristics offered by simply look at the circuit Board.

Note the location of most connectors to connect the internal cables at the front edge of the card and that the developers have tried to free up as much space as possible in the neighborhood of the graphics card. These are two important and characteristic features of the design X570 Aorus Xtreme.

#Packaging equipment

Gigabyte Aorus Xtreme X570 expected delivered in a beautiful box with a fairly informative and not overloaded design. Front of the package is decorated with a large logo Aorus, and on the reverse is a picture of the Board with a listing of its key features and specs. By what properties in the list of the awarded a larger font and highlight, you can guess what is in X570 Aorus Xtreme manufacturer considers important. It is a powerful and high quality power Converter, efficient cooling, PCI Express 4.0, branched controls the RGB led as well as additional network module – 10 Gigabit wired and wireless Wi-Fi 6.


Consider the fee stands out among other X570 solutions not only in the box, but how many accessories in the box fit. Package includes:

  • USB drive with utilities and drivers;
  • six SATA cables;
  • two Wi-Fi antenna with a gain of 4 dBi;
  • module G-Connector for easy connection LEDs, and buttons of the housing;
  • cable to connect LEDs and buttons of the housing;
  • two cables to connect addressable led strips;
  • one connection cable for led RGB strips;
  • one sound pressure sensor;
  • the control unit AORUS RGB Fan Commander;
  • six clips adhesive Velcro for cables;
  • two remote temperature sensor;
  • the screws and the rack mounting M. 2 drives;
  • set of stickers to decorate the case.

Separate the accessories from this list are worthy of more detailed description. For example, here are included in the supplied Wi-Fi antenna.

Or here’s another unusual item of kit — SATA sleeved cables.

A sound pressure sensor is a unique device, which comes exclusively with the flagship Gigabyte boards and allows you to control the noise level of the system.

But the most generous addition to the fee – block AORUS RGB Fan Commander. It is a separate hardware module for fan control and to synchronize RGB lighting on different motherboard accessories.

Gigabyte positions this activity as an indispensable device for modders, but it can be useful to regular users because it expands the possibilities of the Board in the system configuration of PC cooling and management.

#Design and capabilities

Gigabyte Aorus X570 Xtreme stands out from other boards with Socket AM4 not only because of its immodest price. In addition, it can be called outstanding in size and weight. The fact that it is made in the form factor ATX and is almost completely closed with metal casings on both sides. On the outer side of the surface of the Board is almost completely hidden behind the chipset and M. 2 slots, and decorative shrouds passing through the edges of the Board.

On the reverse side of the same Board reinforced with an aluminum plate with “nano” coating, made for the best teplosetevaya.

Efficient heat sink – an important trump card Gigabyte Aorus X570 Xtreme. The fact that it was thanks to a carefully designed cooling system of the chipset and use the back plate X570 Aorus Xtreme complete without a fan on the chipset. This is the only such Board on the market: the rest of the motherboard, built on the same chip, I use active cooling with the use of small fans. This is no problem with temperature of the chip under consideration, X570 Gigabyte does not occur in the passive cooling system copes with heat dissipation from the chip with a thermal package 15 watts. In the process of testing we have never seen a chipset temperature has exceeded 65 degrees.

The secret is not only Gigabyte in size adjacent to the chipset aluminum ingots. The base of the heatsink of the chipset heat pipe is laid, which passes through all the other radiators motherboard, combining into one the cooling system and chipset, and VRM.

And the cooling of the power Converter, the developers of Gigabyte clearly isn’t saved. It uses the classic radiator design used in processor coolers: the core heat pipe passes through the bottom of the radiator, which is fixed in the package slim aluminum fins.

In addition, technology is used in direct contact, and as termoenergetska material selected strip LAIRD having improved thermal conductivity. All this design is quite viable: the power supply circuit of the processor exactly as the chipset, high temperatures did not suffer.


However, this is largely due to the way Gigabyte Aorus made X570 Xtreme power Converter. The Board, based on the X570, have a more powerful power supply circuit in comparison with the predecessors, because older processors Ryzen 3000 increased their energy appetites. For X570 Xtreme Aorus, Gigabyte engineers have collected 16-channel scheme (14 phases for the CPU and 2 phases for SoC) based on power stage Infineon TDA21472 controlled PWM controller Infineon XDPE132G5C.

Such a scheme has two key features. First, giant power: each power stage Infineon are designed for currents up to 70 A, that is, the amount of power Converter can give out current up to 1120 A. second, all 16 phases in it – honest, no superalliance or doubling is not here, and so this scheme will differ not only high performance, but low pulsation. In other words, X570 Aorus Xtreme has nearly the best design of the Converter power among all presented in market Socket AM4-plat. At least a real, separately working 16 phases in the Converter power Board for Ryzen, we still have not seen even once.

By the way, enthusiasts can control the Converter power not only in monitoring, but also directly with a multimeter. To simplify this procedure, the Board has a test point for measuring the base voltage.

Anyway, enthusiasts should be very pleased with how designed X570 Gigabyte Aorus Xtreme. It has hardware buttons Power On and Reset indicator POST-codes, two chips BIOS with the ability to manually switch between them and even the possibility of firmware update without CPU and memory. Curiously, the official site of Gigabyte it promises the installation of chip flash memory with the BIOS in “Cribs” for their easy replacement, but in fact they are soldered to the Board.

Gigabyte Aorus X570 Xtreme offers a very convenient set of expansion slots. There are three PCIe x16 slots, the first and second lines connected to the processor, and the last by the chipset X570. Thus, the first two slots can operate in modes x16/x0 or x8/x8 (with support for SLI and CrossFire), and the third always functions as a x4. When you install the processor cost Ryzen 3000 all slots support PCI Express 4.0 to double bandwidth.

This is equally true of slots M. 2, which is also on the Board of three. Of them closest to the Socket AM4 slot meets the processor, and the second and third slots work through the chipset. They are able to take as NVMe and SATA drives.

Special thanks to Gigabyte, I want to say for the successful arrangement of all these slots. Before the first PCIe x16 left a lot of space, which will insert into the Board graphics cards with three slot cooling system, and it will not block the next slot. And M. 2 sockets are placed so as not to be under the video card and not to suffer from external heating. Anyway, about cooling M. 2 drives thought separately: all slots are closed on top of the aluminum heat dissipating plates, which Assembly are integrated with the chipset.

Another feature of the layout of the Gigabyte Aorus X570 Xtreme – the transfer of almost all the internal connectors on the right edge of the Board while they turn parallel to its plane. This applies to both the 24-pin ATX power supply and many other connectors: to connect the five case fans for led strips, for the administration of the case. Also on the right side of the Board similarly withdrawn six SATA ports, four USB ports 3.2 Gen1 and two USB 2.0 ports.

However, the fit is still not all the connectors. For example, outside the right side on the circuit Board located internal USB port 3.2 Gen2 connectors for the fans of the CPU cooler and various sensors of the monitoring system, two 8-pin power connector, processor power, and a connector for connecting the front panel audio connectors of the case. Even so, specific design X570 Aorus Xtreme helps to optimize cable gear inside the case. Further help can be given and attached to the Board unit AORUS RGB Fan Commander which can shift the power and control of all fans in the system unit.

Backboard also does not look quite usual. And not only that it comes with preinstalled plug I/O Shield. Much more important is the high concentration delivered at her ports: in particular, there is 12 different USB ports that you can even count on the record.

More specifically, among this number, one port is USB 3.2 Gen2 Type-C, five ports (red) – USB 3.2 Gen2 Type-A, two ports (blue and grey) USB 3.0, well, four ports (black) USB 2.0. Support PS/2 Gigabyte decided to refuse, but realized two wired network controller with a bandwidth of 10 GB/s and 1 GB/s. Also on the rear panel has two antenna connector Wi-Fi adapter working in standard Wi-Fi 6 (802.11 ax). And of course, it is not complete without audio, five analog and one digital optical S/P-DIF output.

The audio path in the Gigabyte Aorus Xtreme X570 assembled on the basis of eight-channel codec Realtek ALC1220-VB ratio “signal to noise” up to 120 dB and the DAC chip ESS Sabre 9218 with two 32-bit channels and the ratio of “signal to noise” of 130 dB. Naturally, the engineers have not forgotten to isolate the audio circuit from the rest of the Board and implement in the quality of the oscillator TXC and audiophile capacitors WIMA and Nichicon Gold. In other words, the quality of the integrated sound card is beyond doubt, and gilded audiokniga on the back of the PCB do not seem to be empty showing off.

As has become clear, along with the sound of much attention in the Gigabyte Aorus X570 Xtreme paid online features. What, for example, is that a normal Gigabit network controller Intel I211-AT the developers Board added a second – Aquantia AQtion AQC107. Chip Aquantia is one of the few currently existing controllers wired network that supports connections at speeds up to 10 Gbps.

In addition, Gigabyte Aorus X570 Xtreme added support and wireless network, which is implemented with the latest module Intel Wi-Fi 6 AX200. It is compatible with the IEEE 802.11 ax and configuration 2T2R capable of providing data transmission speeds to 2.4 GB/s. Also in the module AX200 supported standard Bluetooth 5.

At the end of the experience X570 Gigabyte Aorus Xtreme is to say that, among other things, this Board is very advanced in the field of hardware monitoring. So, the Board controls the temperature of seven different nodes of the system, plus it is possible to connect two external temperature sensors (included). Moreover, Gigabyte, and now there is another readout – noise. The required sound pressure sensor supplied. Facilities include a total of eight fans, and it is not only able to determine their type and flexibly control their speed, but under specified conditions is able to stop them completely.

Plus, eight controllable fans can be connected via an additional device AORUS RGB Fan Commander.

Not spared developers and RGB backlight. However, in this case it is relatively unobtrusive. By default, the highlighted area of the Converter power CPU, chipset and sound card, if this user will seem insufficient, then he can add some led strips on their own – for their connection on the motherboard there are four different connector.

All lights naturally driven: for it is a proprietary app RGB Fusion 2.0.
