In two weeks we, apparently, expecting a miracle. Such a conclusion can be made, if to summarize all the assumptions expressed by the user in anticipation of the upcoming announcement of Ryzen processors of the third generation. But even the most bold statements about that in the second half of the year in the market of processors for PC we will see a change of leader (in performance), has not been entirely groundless. At the beginning of the year, at CES 2019, AMD promised that its next-generation processors will increase specific performance (at constant frequency) at least 15 %. And now we have learned that this will make a noticeable increase in clock frequencies, dramatically increasing the number of cores and reduced heat dissipation.

Each of these promises separately, it seems at least very brave. But all at once?! However, all this is possible. Held in the framework of the exhibition E3 2019 special event Next Horizon, AMD explained in detail how it happened that the microarchitecture Zen 2, which originally was supposed to be a trivial translation of Zen on the rails 7-nm process technology, could be a real breakthrough, having the chance to turn the whole CPU market.

Since the release of the first processor microarchitecture Zen took a little over two years. During this time, AMD has managed to release the intermediate generation microarchitecture, Zen+. However, we saw almost no improvement. The essence of the past the updates were actually reduced to a transition from 14-nm to 12-nm production technology, and only. New microarchitecture Zen 2 meeting which awaits us in July, again implies a change in the manufacturing process — from 12 nm to 7 nm with a simultaneous change of production-contractor: now CPU, the company will produce not GlobalFoundries, and TSMC. But that’s not all: along with the process technology changes dramatically and a lot of other things.

To understand how Ryzen 3000 will be unlike their predecessors, just look at any photo of these processors with the removed heat-dissipating cover. One glance is enough to understand that AMD are moving away from the use of monolithic semiconductor crystal. The kernel they are distributed across multiple semiconductor crystals – capleton, some chiplet will be submitted and all the controllers I / o. It should be added that simultaneously with the introduction of radical changes in the construction of AMD reworked the internal structure of the cores and made sure to address the major bottlenecks of previous CPU microarchitecture Zen and Zen+.

In addition, with the advent of Ryzen 3000 changes will affect the whole ecosystem in which to operate such processors. Compatibility of new products with traditional Socket AM4 with it will remain, but completely all their benefits may be felt only in the newer motherboards that will support PCI Express 4.0.

All the numerous improvements and optimizations made in the new generation Zen 2, clearly deserve more than a mere enumeration. Therefore, following the event, AMD’s Next Horizon, which is able to be the representative of our website, we decided to prepare a separate detailed material and elaborate on why the Zen 2 is really cool.

#7 nm technology is the key to everything

The goals set by the company AMD while working on a new microarchitecture Zen 2, was quite evident. The main objective was to improve the performance of processors for both the desktop and server segment, with the compulsory preservation of continuity and compatibility with existing platforms. In other words, it was about the future scalability of existing CPU families Ryzen and EPYC comprehensive and improving their consumer qualities.

A solid Foundation for the design of a Zen 2 was to adapt the new process. In the transition from 14 – to 12-nm standards, which occurred in April last year, processors Ryzen only slightly won the clock frequency and was able fairly to slightly increase its specific capacity. But a new process technology with a resolution of 7 nm was supposed to catalyze a much more significant progress in improving the whole set of consumer characteristics. Due to the fact that long-standing manufacturing partner AMD, GlobalFoundries, abandoned the development of the 7-nm technology, the chip maker had to shift to cooperation with TSMC. And in the end, AMD has made the right decision. Speaking in favor of this number: the basic CPU building block — Quad-complex CCX (Core Complex) with L3-cache 8 GB MB — the production of 12-nm GlobalFoundries, had an area of 60 mm2. A similar complex Zen 2 enhanced with four cores and twice more capacious, 16-megabyte L3-cache, manufactured on TSMC for 7-nm process, occupies almost half the area of 31,3 mm2.

The total CPU crystal (chiplet) Zen 2, as before, is formed of two CCX. That is, it contains eight cores and a cache memory of the third level capacity of 32 MB. The total area of such crystal is only 74 mm2, which is significantly less than 213 mm2, which is the processor chip design, Zen/Zen+, for example, the same Ryzen 7 2700X. Such a noticeable gain in density of transistors has opened the doors for developers AMD opportunities for the improvement of the microarchitecture, which could be carried out without any substantial damage for the cost of the new processors.

At the beginning of this year, AMD announced that the microarchitecture Zen 2 will provide a 15 percent performance advantage compared to the Zen+ due to one only micro-improvements, that is, at the same clock frequency. However, a lot of advantages given and new advanced semiconductor process. For example, at identical energy consumption for Zen 2 promised at least 1.25 times higher performance than predecessors, and with the same performance, the new processors should be almost twice cheaper. Furthermore, AMD does not hesitate even to say that in some situations the advantage of the new processors Zen 2 will be more than 75% compared with the previous Zen+ of the same class and more than 45 % compared to the equivalent solutions of a competitor.

Of course, all these calculations have yet to be be tested independent tests and reviews, which will be released July 7. In the framework of the event AMD is actively operated indicators Cinebench R20, which suggests that if you compare the Zen 2 and Intel with the same number of cores, the AMD wins as single-threaded and multi-threaded performance and power consumption and price.

Just one example: according to AMD, senior Ryzen 3800X OCTA core 7 with a price of $400 is very close to a 500 dollar eight-core Core i9-9900K in single-threaded and multithreaded rendering, but its power consumption is comparable with the consumption of Core i7-9700K.

#Kernel Zen 2: “tik” and “tak” at the same time

According to the original plan, microarchitecture Zen 2 was supposed to be a simple transference of the old Zen design to new process technology. But later, analyzing the weaknesses of its first generation of processors Zen and Zen+, AMD engineers decided to bend and the underlying microarchitecture. And I must say, this plan apparently worked perfectly. Despite the fact that in Zen 2, there are no drastic alterations, the increase in IPC (average number of executed per cycle instructions) by 15 % — a perfect illustration of the fact that everything was done correctly.

At the same time, you need to understand that Zen 2 — microarchitecture very similar to the original Zen/Zen+. All the basic elements of a processor core remained unchanged, and the alterations relate only to improve the efficiency of existing function blocks. Accordingly, the internal configuration of the kernel has not changed: it is able to decode up to four instructions and execute up to six instructions per clock. In addition, remained unchanged support SMT technology: each core Zen 2 can execute two threads simultaneously.

What has changed? As usually happens when working on the refinement of existing microarchitectures, the first place of application of forces engineers unit fetching instructions and predicting transitions. However, the changes are not very obvious, because the basis of this unit continues to lie “neural” algorithm based on the perceptron. Although in General this scheme does not give very impressive results when working with a buffer the objectives of the branch of the first level it provides good energy efficiency, therefore, hence, to abandon it and just added more multi-stage statistical mechanism TAGE (Tagged geometric) working with buffer purposes of branching the second level.

At the same time was increased and the size of the buffer goals of the branch. Table of first level in Zen 2 includes 512 entries instead of 256, and the second level – 7K instead of 4K records. With regard to the zero level, the corresponding buffer, as before, includes 16 entries, but an array of addresses of indirect transitions has expanded to 1K entries. In other words, the new microarchitecture transitions are predicted clearly better than the original Zen/Zen+. This means that situation when the processor needs to completely reset the Executive pipeline because of the incorrectly predicted transition will happen much less frequently.

Another improvement is the Zen 2 was the fact that AMD decided to significantly reallocate resources to caching instructions. The micro-operation cache that stores already-decoded x86 instructions has been doubled to 4096 entries. This classic statement cache of the first level, which keeps the team prior to their decoding, on the contrary, decreased. While the earlier volume was 64 KB, with 4-channel associative, Zen 2, he was cut to 32 Kbytes, while increasing the degree of associativity to 8.

Simulations of AMD, demonstrated that such changes have a positive impact on performance. And judging by what happened to the growth of the IPC, it really is. Interestingly, as a result of changes in the size of the cache memory, the Zen 2 become the processor with the largest cache micro-operations. For example, in the Skylake microarchitecture this cache is 1.5 To operations, while at the Sunny Cove Intel engineers just extended it to 2.25 To operations.

Changes in the input part of the Executive pipeline does not entail any significant changes in the organization of the work of planners. As before, the Zen decoder 2 is able to supply four instructions per clock cycle together with the cache micro-operation, which can do up to eight related instructions, they fill a queue of micro-operations from which the user choose two schedulers: one for integer operations and another for operations with floating point numbers. In this case the integer scheduler can submit to the execution of six micro-operations per clock, and veselinovsky – four.

But a noticeable change in the microarchitecture occurred at the stage of execution of instructions. If to speak about the execution of integer instructions, here — bargain to increase the size of the buffers (like the scheduler, so the register file and reorder buffer) by about 10-15 % — there are additional generating block addresses (AGU). In sum, it means that the number of Executive ports in the Zen 2 has increased from six to seven: four ports for arithmetical and logical operations (ALU) and three port – operations for generating addresses (AGU). As a result, the microarchitecture Zen 2 can initiate two 256-bit reads and one 256-bit write operation every clock cycle. Last version of micro was, for obvious reasons, is limited to only two such operations per clock, and only a width of 128 bits.

But more importantly, in Zen 2, AMD has doubled the throughput of the block floating point operations. He was now fully 256-bit, which means the possibility of direct enforcement AVX2 instructions. In the original architecture of Zen/Zen+ such teams, working with 256-bit registers, before executing crashed onto a pair of 128-bit instructions and were processed in two steps, therefore, from Zen 2 you can expect a doubling in the pace of work with AVX2 code. The execution units in the FPU remained old. There are two devices for the operations of addition and two of multiplication that gives Zen 2 the ability to simultaneously execute two 256-bit FMA-team. There is a very useful ability, a new microarchitecture to initiate a 256-bit forwarding operations data: as a result, the performance of the AVX2 code can occur without any delay. Moreover, in Zen 2 AMD was able to ensure that the processing of AVX2 instructions can be carried out without any reduction in clock frequency, as is the case in Intel.

Along the way, AMD reported that it was able to increase the speed of the multiplications of floating point numbers from four to three cycles. Ultimately, this also contributes to increase the performance of processors with a new microarchitecture.

As follows from the above, microarchitecture Zen 2 was a bit “wider” Zen in the sense of ability of parallel execution of instructions. But at the same time she became “wider” in the sense of working with data. Although the subsystem of the cache memory, a data not structurally changed, she got a bus with more capacity, which allow to obtain the necessary data, without delaying the implementation of AVX2 commands. More specifically, it means that L1 data cache retained size 32 KB per core 8 way set associativity, and the L2 cache, as before, has a volume of 512 KB per core 8 way set associativity, but now the cache can handle two 256-bit reads and one 256-bit write operation per clock cycle at level L1, and one 256-bit read and write per clock cycle at the L2 level. The latency of the cache memory has not changed and is 4 cycles for L1 and 12 clock cycles for L2.

Despite the immutability of the structure of the cache memory, the Zen 2 was improved L2 TLB (buffer address translation). In the first generation of processors Zen the size of this table was 1.5 K, now it increased to 2K, and the latency at the same below. But most importantly, now the L2 TLB supports page 1 Gbyte, which in previous versions of the microarchitecture had not been implemented.

Another notable change in the Zen 2 was the doubling of the size of the cache memory of the third level. In new processors of its size is not 8, but 16 MB on each Quad CCX. So AMD tried to compensate for the dismemberment of the processor into several independent crystals. Developers Zen 2 believe that the growth in the volume of L3 cache will reduce the amount of data transfer between the chipset core and capleton with the memory controller. Maybe so, but do not forget that the increase of the cache memory is almost always accompanied by an increased latency. And she had L3 cache in the Zen 2 is really increased to 40 cycles, while in Zen processors L3 cache had a latency of approximately 5 cycles below.

#From the core to the CCX and CCD, and further to the CPU

We have already mentioned that the design of the processors Ryzen 3000 is markedly different from what was arranged all the past Ryzen. However, CCX-complexes collected from the cores 2 Zen exactly the same as before. In one unit CCX merged 4 cores and 16 MB of shared cache in the third level.

CCX pair within the 7-nm semiconductor crystal and generates CPU chipset, received the acronym CCD (Core Complex Die). In addition to cores and caches, in CCD-chiplet also includes a bus controller Infinity Fabric, by which it shall be ensured connection CCD required for any Ryzen 3000 capleton IO.

In coplete input / output (I/O) processors generation Zen 2 are the so-called extra-nuclear components as well as elements of the North bridge and SoC. In it, among other things, the memory controller and bus controller PCI Express 4.0. Also in the I/O coplete implemented and two of the tires Infinity Fabric required for connection with the CCD chipsetati.

Depending on what processor family Ryzen 3000 it is, it can consist of either two or three chipsetov. In processors with eight cores and less used one CCD-ciple and one I/O-chiplet. In processors with cores more than eight CCD-chipsetov becomes two. However, you need to understand that the processor is still a single entity. Due to the fact that in any Ryzen 3000 memory controller is in I/O-Deplete and he is only one, either kernel can smoothly access any of its areas: no-NUMA configurations, which spoiled the lives of the owners of processors Threadripper, in the case of Zen 2 will not.

It is worth mentioning that the Zen 2 is not the first attempt to go to layout multi-chip processors. Previously, manufacturers had resorted to such an approach. For example, was based on two semiconductor crystal Quad-core Core 2 Quad, and before the same technique was used in the creation of a dual core Pentium D. But then the producers still went on to have a monolithic structure processors, as it was more effective as the number of cores and transferring the processor components of the North bridge. However, the new Ryzen 3000, which includes two or three ciplet, – not a step back. On the contrary, it is the transition to the next level because of AMD new generation of processors is not a simple extensive, increasing the number of cores by adding additional crystals and uses a much more intelligent approach, introducing the use of chipley with different features and combining them into a single entity the specialized high-speed bus Infinity Fabric.

The advantages of using a multi-chip layout is quite obvious. First and foremost, it allows you to reduce costs. Production of chipsetov having a relatively small die area, much simpler than the production of large monolithic processor. Smaller crystals not only allow you to obtain a higher yield of chips, but also more effective placed on a circular semiconductor substrate, which further reduces the amount of waste. In the end, it Chipita configuration allowed AMD to create a very complex processors Ryzen 3000 is relatively inexpensive, despite the fact that their production is organized at the facilities of TSMC’s most advanced and new to industry process technology with the norms of 7 nm.

The distribution functions of the processor in various capleton allowed AMD to save money and even in one aspect. New process technology was not necessarily to use in the manufacture of all parts of the processors. “Thin” advanced standards are important to processor cores, because they directly affect the frequency potential and energy consumption, but there is no need to use them to craft more simple chiplet responsible for the functions of input / output. The I/O chiplet Ryzen in 3000 is made the old-fashioned way – in factories GlobalFoundries for 12-nm process used in the manufacture of Ryzen processors of the second generation.

However, you need to keep in mind that Chipita design gives rise to certain difficulties. For example, in modern processors, very high demands are placed on how connect and interact with each other in different parts of the CPU. To implement such a bus when mnogoshipovyh the layout is a bit trickier. However, this problem was solved by engineers of AMD. Processors Ryzen first and second generations, although they were based on monolithic kernel, used for connection the CCX and the memory controller, North bridge and elements of the SoC specialized tyre Infinity Fabric. New Ryzen 3000 processors used the second version of this bus: it is responsible for data transfer between all chipsetati.

Frankly, to how to operate the Infinity Fabric, had previously been well-founded claims: it is not always able to provide the required level of performance when interacting processor cores with L3 cache and memory controller. In processors Ryzen 3000 AMD has tried to correct the main shortcomings of the Infinity Fabric.

First, this bus has been expanded twice: now its width is 512 bits, which means a doubling of the capacity and the transfer of 32 bytes per clock in each direction. The developers claim that this step they went in the first place because of the emergence of Ryzen in 3000 support PCI Express 4.0, but it is obvious that a more productive bus, which connects all key components are CPU, will play a positive role in many other cases.

Secondly, Infinity Fabric is now “unleashed” with the memory controller frequency. Earlier the frequency of this bus was synchronized with the memory clock, which on the one hand, leads to a strong dependence of the performance of processors Ryzen speed assigned to the DDR4 SDRAM, and the other – let overclocking memory above 3466-3600 MHz. Now the tyre Infinity Fabric will be able to work with the memory controller not only synchronous, but less than half relative to the frequency with the use of divider 2:1. It is — at least theoretically — means a much greater freedom in the choice of speed of memory, though AMD continues to insist that the synchronous mode to Infinity Fabric will still provide better performance, and more optimal with Ryzen 3000 to use modules DDR4-3600 with low timings.

However, it is already known that the memory in Socket AM4-systems, processors Ryzen 3000, will do much to disperse.

For example, AMD showed working memory module in the mode DDR4-5100 in the system built on Socket AM4-motherboard MSI MEG X570 Godlike.

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

Shop Barnes & Noble''s Movies & TV Bestsellers

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

YYC2-821660511060 Lenovo ThinkPad T430 Laptop PC - Intel Core i7-3520m 2.90GHz, 8GB RAM, 500GB HDD, 14" 1366x768(HD), Intel HD Graphics 4000, DVD-RW, GigE, Bluetooth, Win 10 Pro 64-bit, Refurbished - 821660511060

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.

Overview of Gigabyte Aorus X570 Xtreme 16-phase power and passive cooling of the chipset

Samsung J7 V just $5 mo. New device payment purchase req'd. Plus, free shipping.

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.
