Test the 3DNews laboratory has already examined a few motherboards on the chipset X470 — this chipset came with the processor Ryzen second generation. Board based on the younger of the modern chipsets — B450 — was presented in June at Computex 2018. However, it so happened that in our market B450 device went on sale in August. Model GIGABYTE AORUS B450 PRO is one of the most promising in its class. And now you know why.

#Specifications and packaging

At the time of this writing in the catalog on the official GIGABYTE website was listed four models of motherboards based on chipset B450. So, in addition to the B450 AORUS PRO for sale you will find version B450 AORUS ELITE. These boards are very similar, but somehow “elite” modification received less quality sound chip and network controller. Also B450 AORUS brags ELITE USB 3.1 Gen2 panel I/o, but that is quite logical, is somewhat less PRO-version. Full specifications GIGABYTE AORUS PRO B450 indicated in the table below.

  • the screws for fastening the M. 2 drives;
  • adapter G-Connector, to facilitate connection of the bodies of management of the case.
 

#Design and capabilities

We have before us a charge made in a classic form factor ATX (305 × 244 mm). The B450 PCB of GIGABYTE AORUS PRO is not “mingled”, so the elements on the device located on the comfort of to build a distance from each other. In addition, the holes for fastening the Board to the casing is placed exactly on the right edge — in the budget motherboard with reduced PCB (with dimensions 305 × 225 mm and less) are sometimes part of the PCB sags, connect the memory modules and the 24-pin connector of the power supply in such devices is not very convenient.

Distance between CPU socket and DIMM slots is more than 35 mm. This is quite enough to without any problems to install the CPU waterblock DLC NZXT KRAKEN X62 — protruding from his tube it does not overlap the middle plug to install RAM.

Expansion slot PCI Express x16, which will be installed video card, soldered the second. The first is a PCI Express x1 (PCIEX1_1 marking). Therefore, B450 GIGABYTE AORUS PRO with no problems “shelter” any supercooler. In total on the PCB we find four expansion slots — three of them are PCI Express x16 slot marked x16 slots, the pciex4 slot and PCIEX1_2. They work, as you might guess, in the mode of x16+x4+x1. The upper PEG-the port complies with the PCI Express 3.0 standard, other connectors operate in a mode 2.0. Moreover, if the involved connectors or PCIEX1_2 PCIEX1_1, the pciex4 slot operates in x2 mode.

In addition, I note that the Board supports AMD CrossFire, but you can use it in motherboards with the chipset B350/B450 makes no sense. This, perhaps, is the main difference of devices based on low and high sets of logic. In X370/X470-boards supported technologies AMD CrossFire and NVIDIA SLI mode x8+x8 PCI Express 3.0.

PEG port for the graphics card is enhanced by reinforcement, and three PCI Express x16 slots are double locking and additional soldering points. In total, according to the manufacturer, these design solutions strengthen connectors 1.7 times when the load on the fracture, and 3.2 times when the load on the pulling.

To the layout of components B450 GIGABYTE AORUS PRO I have only one complaint: the primary M. 2 slot soldered poorly, as when using the appropriate solid-state drive, it will always be covered by the graphics card. Given the fact that on the circuit Board are soldered two M. 2 port, it would be logical to make the main bottom connector.

But I have no questions to the pin connectors for fans. Them on a PCB placed as many as five pieces. All the connectors — 4-pin, supported and even a fan power up to 24 watts. Using the technology Smart Fan 5 can be controlled by impeller with shim and without it (fan with 3-pin connectors). SYS_FAN3_PUMP the bottom connector is designed for connecting the pump of the liquid cooling. If the system is to be used unattended, “water”, then this arrangement can be considered a failure — the cable from the waterblock just do not make it to the bottom edge of the PCB. If you build a PC custom DLC, on the contrary, to connect the pump with the reservoir, which will be assigned, for example, on the bottom of the case-tower, it will be very convenient.

 

GIGABYTE AORUS B450 PRO has two M. 2 ports, equipped with aluminum radiators. The manufacturer claims that the cooling system Thermal Guard effectively dissipates heat, helping to eliminate the cause of the throttle with respect to M. 2 devices“, but the specific data, unfortunately, does not. Top connector allows you to install SSD formats 2242/2260/2280/22110, supports SATA 6 Gbps and PCI Express 3.0 x4. The lower M. 2 slot supports installing the SSD 2242/2260/2280 formats, it summed up the two lines PCI Express 3.0.

Also on Board there are six SATA connectors 6 GB/s. Pads grey (ASATA3_0 and ASATA3_1) are wired separately and are located near the 24-pin power connector. This is done on purpose: if slot M2A_SOCKET to establish M. 2-SATA drive, then turns off ASATA3_1. If you install SSD with PCI Express interface, then disconnected both the SATA connector is gray.

When using the slot will be disabled M2B_SOCKET black SATA3_2 connectors and SATA 3_3.

GIGABYTE AORUS PRO B450 is equipped with a high-quality Gigabit network controller Intel I219-V and sound chip Realtek ALC1220-VB. The audio codec has a ratio of “signal to noise” of 120 dB and an intelligent amplifier that automatically determines the impedance of the connected headphones. Separately, the manufacturer notes that the new controller enables us to convey to the Network the voice with a microphone connected to the 3.5 mm Jack on the front or on the rear panel. In addition, the tract is equipped with special capacitors WIMA FKP2.

The I/O panel are soldered two port USB 3.1 Gen2 — A – and C-types. Other interfaces listed in the table. GIGABYTE AORUS B450 PRO is not in the set of plugs on the back wall of the housing — this element is already embedded in the I/o Board. Overall this is a very reasonable solution — other manufacturers should take note of it.

In addition to the pads to connect the case buttons, among integrated interfaces are 13-pin TPM HD Audio and two USB 2.0 and one USB 3.1 Gen1. Here, in the bottom of the Board there are two connectors RGB-strip — 5 – and 12-volt. Another port for the 5-volt tape is soldered near the 24-pin power connector. And just below the CPU socket has a port LED_CPU — connected backlight CPU cooler.

On the Board itself highlighted the audio track, the inscription AOURUS and chipsety radiator. Read more about how to assemble a PC with a colorful and harmonious lighting, you can read here.

The power subsystem consists of the PWM controller IR95712 and seven phases, although the manufacturer boasts a hybrid diagram 8+3. In any case, nice to see such a Converter power supply device based on a younger model. Four channels are directly responsible for the work of the CPU, three for the NB/SOC. In the first case, each phase comprises two inductors (here-hence the stated eight) and three transistors NTMFS4C06N and NTMFS4C10N from ON Semiconductor. The second one throttle and two MOSFET NTMFS4C06N. The hottest elements of the VRM-area, field-effect transistors are cooled by two rather large aluminum radiators.

 

In the end, the power Converter does not overheat even when overclocking the CPU Ryzen 7 1700. Maximum heating power supply components does not exceed 85 degrees Celsius. As you can see, in terms of reliability of GIGABYTE AORUS PRO B450 everything very well.

So lately into my hands from time to time fall GIGABYTE, the title of which is the word PRO. In 2018 my authorship out related models such as the AORUS PRO B450 and Z390 AORUS PRO. And you know what? In both cases we were dealing with a sturdy “workhorses” cards, which perfectly showed themselves in the coordinate system of “price — quality”. The character of today’s review — GIGABYTE model AORUS X570 PRO — fits into the designated category.

#Specifications and packaging

At the time of writing, on the official GIGABYTE website was listed just nine motherboard models based on the new chipset X570. While X570 AORUS PRO exists in two versions — if you need a device with a preinstalled wireless module, look at the selling option called X570 AORUS PRO WIFI. Otherwise the versions are identical. Main technical characteristics of the device shown in the table below.

I note that details about the set logic X570 you can read in the article “AMD Ryzen 7 3700X: Zen 2 in all its glory, “although the hereafter will necessarily be distinctive features of the new boards for the platform AM4.

The device is Packed in a small but colorful cardboard box. The packaging has a quite recognizable appearance, but the main thing is, of course, its contents. In addition to the Board, it was a lot of accessories, both useful and not:

  • user manual;
  • sticker with the logo AORUS;
  • disk with software and drivers;
  • four SATA cable;
  • the screws for fastening the M. 2 drives;
  • extension cable RGB tape;
  • adapter G Connector to facilitate connection of the bodies of management of the case.

In General, we have everything you need in order to start the Assembly of the system unit.

#Design and capabilities

So, we have motherboard form factor ATX. The manufacturer uses a full size PCB, that is, its dimensions are 305 × 244 mm. Many know the consequences of application of the PCB smaller. So, when attaching the circuit Board in the housing the right side will SAG and can be deformed upon connection of the memory modules or the main connector of the power supply. In the case of the AORUS PRO X570 unexpected “twists of fate” of this kind should not happen.

GIGABYTE X570 AORUS PRO

GIGABYTE AORUS X570 PRO: five PCI-E connectors

Since we are talking about the form factor ATX, the manufacturer may place on the motherboard up to seven expansion slots. However, X570 AORUS PRO boasts only five PCI Express slots. In the photo above, we see that the part of space occupied by the M. 2 ports required for installing SSDs. Well, cry about it just not worth it.

Motherboard supports technologies such as AMD CrossFire (hardware manufacturers, as we still use this term, although it is slowly disappearing) and NVIDIA SLI. When connecting two digital devices to the PCI Express x16 slots they will work according to the scheme x8+x8. If you read the review Ryzen 7 3700X, you know that now we are talking about PCI Express 4.0. Of course, this would require the processor family Ryzen 3000 (not the G-version, as it uses the now outdated architecture Zen+). In the case of “stones” Ryzen 2000, all the expansion slots will work according to the standard number 3.0.

The third PCI Express x16 slot always runs at x4 speed — these lines are provided directly by the chipset. They also — depending on the generation of processor Ryzen — will work with bandwidth or standard 4.0, or 3.0. And on the PCB X570 AORUS PRO has two PCI Express x1 4.0/3.0.

In my opinion, the location of the expansion slots at the test Board as a whole was successful. Firstly, the main PEG port is noticeably removed from the socket. In the end, X570 AORUS PRO will allow you to set any, even the largest air cooler. We also without any problems, without removing the video card, can install RAM modules.

Secondly, between the main PEG-ports a decent distance — such that we can combine in SLI/CrossFire arrays, even video cards with translatewiki coolers. I believe that in 99.9% of cases in the system will still use a single graphics accelerator, and therefore with one port PCI-Express x1 have to say goodbye. And another point: the graphics card will block the fan of system of cooling of the chipset and translateby 3D accelerator still soldered below the M. 2 slot.

Please note that the main PEG ports and DIMM slots are reinforced. Ports also have additional fixation and increased the number of soldering points on the PCB. In total, according to the manufacturer, these design solutions strengthen connectors 1.7 times when the load on the fracture, and 3.2 times when the load on the pulling.

When you install the DLC NZXT KRAKEN X62 I had to part with one DIMM slot — the ones closest to the CPU socket. This point is important to consider if you want to build a system with a liquid cooling system similar designs (when hoses “dropsy” are attached to the waterblock on the right) and if you plan to install into the system four memory modules.

GIGABYTE AORUS PRO X570 soldered seven 4-pin connectors for fans connection. The fee traditionally GIGABYTE allows you to control the impeller with shim and without it (fan with 3-pin connectors). Thanks for this Smart Fan 5. It supports even the fans power up to 24 watts. In General, the connectors for the “Carlson” is located successfully. I’d only moved to the side of the CPU socket connector SYS_FAN5_PUMP, which is the closest to 24-pin power port. The fact that connecting it to the pump maintenance-free DLC, not so easy to hide the protruding wire. Still want to collect a beautiful system units.

But SYS_FAN6_PUMP connector is successful. It will be useful to you if you are going to install in PC full custom “dropsy”. In Tower-building, as a rule, a tank of refrigerant and a pump mounted in the front portion thereof.

Speaking of beauty. At the top right of X570 AORUS PRO has just two ports for connection of led strips: one is designed for 12-volt RGB accessory, one for the 5V addressable strip. Exactly the same “sweet couple” and soldered at the bottom of the PCB. Another 12-volt plug is located next to the socket AM4. Is connected to the backlight of the cooler.

The Board highlighted left edge and a small strip on the plastic housing. Note that when using RGB Fusion 2.0 the user has the option to install 11 modes of illumination.

The disk subsystem includes six SATA 6 GB/s and two M. 2 slots. Now they do not share bandwidth with each other. The primary M. 2 connector allows you to install SSD sizes 2242, 2260, 2280 and 22110. It supports both SATA mode and in the mode PCI Express. The second option involves the CPU of the line: in the case of Ryzen 3000 we are talking about the 4.0 standard, in the case of Ryzen 2000 — on 3.0. The second M. 2 slot has the same features, but only in this case the PCI Express coming from the chipset.

In my opinion, the main M. 2 port is successful. It will not be covered by the graphics card, and if using an air CPU cooler installed this SSD socket will be additionally Abdovitsa. And here is an additional M. 2, I think, it was better to unsolder the lower PEG of the second port near the PCI Express x1 and chipset. With this arrangement, the SSD will not (even partially) covered by the video card, if the system has only one graphics accelerator. We can safely say that the era of NVMe drives come in fully — consequently, the presence in PC of two M. 2 SSD doesn’t look like something outlandish.

GIGABYTE AORUS X570 PRO features a high-quality Gigabit network controller Intel I219-V and sound chip Realtek ALC1220-VB. The audio codec has a ratio of “signal to noise” of 120 dB and an intelligent amplifier that automatically determines the impedance of the connected headphones. Separately, the manufacturer notes that the new controller enables us to convey to the Network the voice with a microphone connected to the 3.5 mm Jack on the front or on the rear panel. In addition, the tract is equipped with special capacitors WIMA FKP2. Here we see a complete copy of the audio subsystem used in the AORUS PRO B450.

The I/O panel GigX570 AORUS PRO you’ll find two USB 3.1 Gen2 A-type and another of the same, but C-type. Three USB connectors meet the USB 3.1 Gen1, and four 2.0. From video outputs there are HDMI only. The rest of the space on the rear panel is a RJ-45, optical S/PDIF output and five 3.5-mm mini-jacks.

As for the internal I/O ports X570 AORUS PRO on the edges of the PCB are soldered device from a single USB 3.1 Gen2, two USB 3.1 Gen1, two USB 2.0, TPM and F-audio.

From pleasant trifles I note the presence on Board button Q-Flash with which BIOS matplot you can upgrade, not even including the computer.

According to the manufacturer, Converter power X570 AORUS PRO has 12+2 phases — sounds impressive, agree. Controls the lines VRM PWM controller Infineon IR35201, which, as you know, works according to the scheme 6+2. This means that in reality the power subsystem X570 AORUS PRO, responsible for the operation of the computational cores has six phases — they simply double (on the reverse side we see the PWM-doubles Infineon IR3599). Each such channel comprises two inductors and two MOSFET Infineon IR3553, each of which can withstand a load of 40 A. Each of the two phases responsible for the SoC component of the CPU consists of one inductor and four MOSFETs ON Semiconductor — two transistor 4C10N and 4C06N.

In General, the power Converter X570 AORUS PRO inspires confidence. Moreover, field-effect transistors therein are cooled by two large aluminum radiators, connected by a copper deplorable. Details about the efficiency of the power Converter of this Board I’ll explain in a second part of the review.

Please note that the chipset of the device is cooled by an active cooler. We’ll get used to this state of Affairs, because many X570-the motherboard uses a similar cooling system. The fact that the level of heat the chipset up to 14 watts. As you know, AMD is, in fact, uses a modified I/O-chiplet, which is used in server processors EPYC Rome. It is produced using 14-nanometer technology and, as you can see, needs active cooling.

I have already noted that in some cases chipsetov fan of the cooler will be covered with a graphics card. This leads to the fact that the chipset if you use temperature sensors the Board is heated to 55-60 degrees Celsius. The fan is quite loud only when turning on the computer, and then it takes a few seconds and it ceases to be heard.

Of course, over time the impeller gets clogged with dust and may begin to make other sounds. However, we must understand that for the “health” of the system unit entirely meets its owner — don’t be lazy as often as possible to clean your PC from dust.

AMD Ryzen 3900X 9: a split personality

Promo code not required. The deal applies to a specific group of goods. The deal is available for all customers of the e-store. The deal is available without amount restrictions

Last week AMD gave the press a computer a nightmare. The company’s desire to release their new 7-nm products certainly in “beautiful” date July 7 (7.07) led to the fact that the preparation for their announcements was carried out in a wild rush and very messy. For example, samples Ryzen 3000 arrived in our lab just five days before the “hour X”, but even during these five days we have been updating the BIOS of the test motherboard based on set logic X570, which not only corrected mistakes and added platform stability, but also seriously affect performance.

Because of this, we were faced with a difficult choice: either to engage in continuous retesting of the new processors at the next firmware versions and abandon any attempt to catch with the publication of the review of the first media micro Zen 2 at the end of information embargo, or for use in publications are not the most current performance data. But in the end was chosen as a compromise: the review was divided into two parts. The first part, which is dedicated to eight Ryzen 7 3700X, you most likely have already read – it appeared on our website in the very moment when the world started selling Ryzen 3000. And this article is the second part, and it will focus on the older 12-core representative of a new family, the processor Ryzen 9 3900X.

This separation allowed us again to recheck all the results on the last (at the current moment) version of firmware for the motherboard and ensure that the first buyers Ryzen 3000 will have at its disposal is the level of performance, referred to in this material.

However, no certainty that this performance level does not undergo regular adjustments in the very near future, we have. The fact that the five different versions of the BIOS of our test motherboard that we have tested for five days of experiments, change in the system is quite fundamental. Them AMD not only in optimizing memory controller, but “tighten up” the variable Boost 2 technology Precision, increasing the real frequency of the processor at the expense of efficiency. It is quite possible that later the company will want to change the operating parameters of their processors again. In other words, today’s tests Ryzen 3000 is only a preliminary acquaintance, which occurs at an early stage in the life cycle of new products.

Perhaps in the circumstances it would be right to wait a few weeks and thoroughly test the new chips, when the situation with them already ustakanilos: motherboard manufacturers will prepare a stable version of firmware, based on the AGESA libraries that have all the essential optimization and AMD will come to a final understanding, a balance between performance and energy efficiency it wants to achieve in the end.

However, to do so would be not too rational. The hype created around the new version of the microarchitecture of authorship and the first AMD desktop processors based on it, is so great that the computer community is ready to swallow any information, even if it is in the nature of rough estimates. Therefore, the review Ryzen 9 3900X still goes on our website after the review Ryzen 7 3700X, despite the clear “dampness” of these products. Later, to put the final point in the subject’s performance of new products, we’ll just test them again.

#Of eight — twelve: topology Ryzen 9 3900X

Together with new microarchitecture Zen 2 AMD introduces into use the new topology. Processors now are not a monolithic crystal, and are assembled from several components. This allows the company under the old ecosystems Socket AM4 to offer a new powerful CPU, with 12 and 16 cores. The budget for such multi-core processors consists of nearly 10 billion transistors, but they are distributed over several semiconductor crystals, similar to the way it was done in the HEDT CPUs Ryzen Threadripper.

However, unlike Threadripper desktop CPUs are not constructed of the same components, they use semiconductor crystals of two different types. First, it is OCTA-core “computing” CCD chipley produced for 7-nm process at TSMC companies. Each chipset combines two CCX-complex, containing four cores and 16 MB cache in the third level. Second, an additional 12-nm I/O-chipset controller memory controller, PCI Express 4.0 and elements of the SoC, which is responsible for input / output.

Given the fact that Ryzen 9 3900X – dwenadzatiperstnuu processor, it is constructed from three semiconductor crystals: two 7-nm CCD-chipsetov, with 3.9 billion transistors with an area of 74 mm2, and 12-nm I/O chiplet area of approximately 125 mm2, consisting of 2.09 billion transistors. Connect chipley tyre Infinity Fabric, the same as that used for communication between CCX-complexes within a single CCD chiplet. And, most importantly, chipley nuclei have no direct link connecting them, and all internuclear interaction, is constructed using the I/O-ciplet, who also plays the role of the switch.

It is easy to calculate that a 12-core CPU Ryzen 9 3900X needs to be active not all the cores available. And it’s true: one computational kernel in each CCX available-complex hardware locked, which makes any of the initial 16-core stock CPU with 12 cores. In this case, limiting the number of cores is partly a forced measure, as 16 cores hard enough to enter in a valid Socket AM4 limits energy consumption. But AMD does not abandon the idea of release and 16-core Socket AM4 product. This project is scheduled for the autumn, it will be released under the name Ryzen 7 3950X, but the manufacturer will have to resort to a special education careful selection of semiconductor crystals.

Chipley approach allows to obtain several advantages. First, it allows to simplify the design and production of processors, but also offers ways for easy scalability of the products. Second, because of the separation of functions chiplets different types of AMD had the opportunity to avoid duplicating nodes, we need in a single number, for example, memory controller or bus controller PCI Express 4.0. Due to the fact that all these blocks are put into a single I/O-chiplet to which the CCD chipley have equal access, a logical processor is a monolithic structure with centralized mechanisms of memory accesses and to external devices. Any hints on the usual users Threadripper NUMA-modes in the AM4 Socket system, all cores in 12 – and 16-core processors have exactly the same access to the array RAM.

Everything said is illustrated by the results of practical measurements. As for memory access, then it is all really OK. Ryzen 9 3900X shows approximately the same latency that OCTA-core processor Ryzen 7 3700X. This means that the connection to the I/O chiplet with the memory controller not one, but two CCD chipsetov does not entail any negative effects. Thanks cipitol the layout of memory for all cores do seem to be a single array with the same delay.

And by the way, please note, Ryzen 9 3900X is not subject to the same problem with lower half-bandwidth of the recording, which we found Ryzen 7 3700X. It turns out that the memory controller I/O coplete Ryzen 3000 just optimized to work with two CCD chipsetati and when you connect one chiplet full performance can not give.

But much more disturbing than the speed of the memory cause a latency of internuclear interaction. It seems that the location of the nuclei in different CCD-chiplet should impose a substantial penalty in data transfer between them. For example, the latency in the exchange of information between cores in different crystals in the processors Threadripper, one and a half times higher than when transfers between different cores CCX-complexes within a single crystal. However, surprisingly, such problems have Ryzen 9 3900X does not exist. Here the internuclear interaction between the nuclei belonging to different CCX-complexes, leads to the same delays regardless of whether we are talking about the CCX in the same or in different CCD-chiplet.

And this is a really serious achievement. Thanks to the centralized scheme of the mutual connection of cores, multi-processor Ryzen 9 3900X from the side looks like a completely solid solution. No additional penalties for mercapital communication do not. And therefore, there is no reason to compare Ryzen 9 3900X with Threadripper. What AMD offers at this time – a full 12-core processor, not the Assembly of the two shestiyaderny in a single housing.

It was logical, based on the number of cores and threads: Ryzen 7 3700X – shestnadtsatiletnij and OCTA-core CPU, like Core i9-9900K. In fact, however, AMD continues to follow his principle “we will have more cores for the same money than the competitor” and contrasts the Core i9-9900K completely different your processor. The recommended price of $499 in the new lineup got a 12-core, 24-threaded Ryzen 9 3900X, and it is positioned as alternatives to the five hundred-dollar osmeteria Core i9-9900K.

Already in the simple comparison of the characteristics Ryzen 9 3900X against the Core i9-9900K AMD processor looks very impressive. Time and a half because in addition to the superiority in number of cores and threads Ryzen 9 3900X can offer and huge L3 cache with a total capacity of 64 MB, while in a competing processor, the cache memory of the third level less than four times. In addition, Ryzen 9 3900X can boast official support for DDR4-3200 and accelerated version of PCI Express 4.0.

The only thing Ryzen 9 3900X has not yet been able to surpass Intel CPUs is the clock frequency. They are for 12-core are declared in the range of 3.8-4.6 GHz, although in reality it will strive to get closer to its upper bound due to aggressive technology Precision Boost 2. However, lower frequencies are quite Ryzen 3000 kompensiruet his outstanding IPC (the number of executable per clock instruction): as we have seen, in many cases at the same frequency core 2 Zen work even faster cores Coffee Lake Refresh.

In the end, to find in the camp of Intel suitable opponent for Ryzen 9 3900X with the same number of cores, we will inevitably have to turn to heavy HEDT platform LGA2066. Only in its composition there are 12-core Core i9-9920X, but it is estimated at $1 199, that is 2.4 times more expensive than AMD’s flagship news related to the mass platform Socket AM4. Here, of course, one could argue that the HEDT platform offering Quad-channel memory controller and more PCI Express, however, such possibilities can hardly be attributed to the vital for most users things. And that means Ryzen 9 3900X actually blurs the line between HEDT and Socket AM4. Thanks to this gift from AMD users conventional bulk systems can now get the level of multithreading, which recently was only available to owners of heavy and expensive platforms LGA2066 or Socket TR4.

Let’s look at the characteristics of Ryzen 9 3900X more. Among the processors in the consumer segment this processor looks like an alien from another world. So it turns out due to the increased number of cores and huge cache, and these features are acquired thanks to the introduction of kiplenge design. In other words, it is legitimate to say that Ryzen 9 3900X – a vivid demonstration of the correctness of the course taken by AMD. The company’s engineers “flick of the wrist” collected from the two CCD-chipsetov mass processor to catch up with that in the baseline characteristics of the Intel in the near future obviously will not be able to.

 

Another feature Ryzen 9 3900X – relatively good frequency. Typically processors with more cores, lower clock frequency, but in this case the opposite happened. And nominal, and maximum frequency Ryzen 9 3900X superior cosmedent Ryzen 7 3700X, and even ahead of eight Ryzen 7 3800X terms of the maximum frequency. This means that Ryzen 9 3900X will be as good in multithreaded applications or when a more simple load on a limited number of cores. That is, the processor must be universal, not a niche solution for demanding work loads, this is technology Precision Boost 2 in aggressiveness which Ryzen 3000 we have already seen.

For example, look how are real working frequency Ryzen 9 3900X in Cinebench R20 load on different number of cores. The minimum frequency observed at full load CPU rendering, start from 4,025 GHz.

And for example, when OCTA core load, the processor is capable of operating at a frequency of 4.1 GHz, that is at least not slower than Ryzen 7 3700X. In the case of downloading a small number of cores Ryzen 9 3900X comes on frequencies above a 4.3-4.4 GHz.

When meeting with Ryzen 7 3700X we drew attention to its high operating temperatures. Ryzen 9 3900X, in which nuclei and a half times more, was also affected by this issue, and even more.

The stress load is received by the utility Prime95 29.8, raises the temperature of the CPU in the nominal mode up to 95 degrees (with the cooler Noctua NH-U14S) and the Converter power the motherboard reports the CPU consumption of about 190 watts of electricity.

It looks somewhat normal, and we were able to get unofficial confirmation that in the latest versions of the BIOS that came for X570-motherboard before the announcement of Ryzen 3000, technology of Precision Boost 2 is configured with a strong overestimation of the allowable limits for the consumption and heat dissipation that automatically provides an additional increase of operating frequencies. However, apparently, the initiator of this “overclocking out of the box” is the AMD, and it is unclear whether this mode will now become standard, whether it is imposed only on the output time of the first wave of reviews to get more positive reviews in the press, and will be removed.

#Acceleration

About acceleration Ryzen 9 3900X not much to tell. Here everything is done to us. Technology parameters Precision Boost 2 12-core unscrewed to the limit, and this CPU works at the maximum possible under dynamic acceleration frequencies without any additional configuration.

If to speak about static acceleration, the power voltage setting To 1.2, it was possible to achieve stable operation at a frequency of 4.0 GHz. Unfortunately, the processor is strongly heated, and it almost completely ties the hands of overclocking.

It is doubtful that in this static acceleration there is some practical sense. Technology Precision Boost 2 even at 100% load on CPU provides a slightly lower frequency, but when loaded by the operation of a part of cores it is able to provide for Ryzen 9 3900X noticeably better performance.
