In the range of ASUS, there are 19 motherboard on the chipset Intel Z390. Potential buyer can choose from models like the elite series ROG or TUF ultra-reliable and Prime, has a more democratic prices. Received by us on the testing Board just refers to the last series, and even in Russia is slightly more than 12 thousand rubles, for solutions Intel Z390 relatively inexpensive. We will focus on models of the ASUS Prime Z390-A.

Having on Board all necessary to create a game system or a productive workstation, fee slightly simplified developers touched on almost everything from the CPU power circuit and ending ports. Thus all the possibilities for overclocking the CPU and RAM in the ASUS Prime Z390-A is. More about all this we will tell you in this article.

#Packaging equipment

ASUS Prime Z390-sealed in A small cardboard box on the front side which shows the Board itself is marked with the model name and series and lists the technologies supported. Not forgotten and a mention of the support system backlight ASUS Aura Sync.

 

According to the information on the reverse side of the Board you can find almost everything, including characteristics and key features. Very briefly the characteristics of the product mentioned on the sticker from the end of the box.

Inside the box for more protect to pay no — she’s just laying on a cardboard tray and sealed in anti-static bag.

The contents are pretty standard: two SATA cable, plug on the rear panel, CD with drivers and utilities connection bridge for 2-way SLI, manual and screws to secure the drives in the M. 2 ports.

The bonus is a coupon for a twenty percent discount when buying brand cables in the store CableMod.

Board is produced in China, and provides a three year warranty. We will add that in Russian stores it is already being sold at a price of 12,5 thousand rubles.

#Design and features

Design ASUS Prime Z390-A modest and concise. On the PCB there is no bright inserts or the attention-grabbing detail, and all the colors consists of a combination of white and black color and silvery color of the radiators. This fee can hardly be called boring, even though it’s the last thing you can pay attention to when choosing the basis for the system average performance.

 

From the individual design elements highlight the plastic covers on the ports I / o and the chipset.

 

They have semi-transparent Windows, through which is visible light. We will add that the fee is equal to 305 × 244 mm, that is, it refers to the ATX format.

Among the main advantages of the ASUS Prime Z390-A manufacturer allocates power circuit elements DrMOS, eight-channel sound Crystal Sound, as well as support for all modern ports and interfaces.

Before a detailed analysis of the components of the motherboard will give their location on the diagram provided in the instruction manual.

 

On the rear panel of the Board displayed eight USB ports, three types, combo PS/2 port, two video outputs, mains socket, optical output and five audio connectors.

As you can see, all modestly and without frills, but it is unlikely the developers here can be accused of compromise, because the base set of ports, is implemented here.

All the radiators and shrouds are attached to the PCB with screws. Their removal took less than a couple of minutes, then ASUS Prime Z390-A appeared in its natural form.

The textolite is not overloaded with elements, a lot of free of chip areas, but it is quite typical for motherboards of a mainstream segment.

CPU socket LGA1151-v2 is not characterized by some signature features — it is completely standard.

In the specifications of the motherboard claimed to support all modern Intel processors this socket, including the recently released Intel Core i9-9900KFfor which you need to flash BIOS 0702 or later.

The system processor power on ASUS Prime Z390-A is organized according to the scheme 4 × 2 + 1. In the power circuit uses assemblies DrMOS integrated drivers NCP302045 production ON Semiconductor is able to withstand peak loads up to 75 A (the average current is 45 A).

Power management on-Board digital controller Digi+ АЅР1400СТВ.

The power Board is provided by two connectors — 24 – and 8-pin.

 

The connectors are made of ProCool technology to which the stated more secure connection to cables with lower resistance and improved heat distribution. This visual differences from the normal connectors on the other boards was revealed.

No differences in Intel Z390, crystal which is in contact with a small heat sink through thermal pads.

However, here they could not be.

Board is equipped with four DIMM slots for RAM standard DDR4, which in pairs are painted in different colors. Priority to install one pair of modules are light gray slots that are marked directly on the PCB.

The total amount of memory can reach 64 GB, and the maximum frequency stated in the specs – 4266 MHz. However, to achieve this frequency will have to try to pick up as a good processor and the memory, but proprietary technology OptiMem II should be possible to facilitate rest. By the way, the list of officially tested modules on the Board today contains 17 pages of fine print, but even if your memory it will not, then with a probability of 99.9 % for Prime Z390 Is A will to work with her, because motherboards are extremely omnivorous to the memory modules and, as a rule, well, they dispersed. We would add that the power system memory single channel.

ASUS Prime Z390-A is equipped with six PCI Express slots. Three of them are made in a design of x16, and two slots have a metallic shell. First x16 slot is connected to the processor and the processor uses 16 lines PCI-E.

The second slot of the same form factor can only work in mode PCI-Express x8, so the fee is, of course, supports NVIDIA SLI and AMD CorssFireX, but only in combination x8/x8. The third long PCI-Express slot only works at x4 speed using chipset line. In addition, the Board has three PCI-Express 3.0 x1, also implemented by the chipset Intel.

The operation mode of the PCI-Express implemented circuits-switches ASM1480 production ASMedia.

As for the video output Board with built-in graphics core, they are implemented by the controller ASM1442K.

The Board has the standard six SATA III ports with a throughput of up to 6GB/s implemented by the possibilities of the same set of system logic Intel Z390. In their placement on the PCB of the developers do not have anything wise and arranged all the connectors of one group in a horizontal orientation.

There are on-Board ports and M. 2 in the amount of two pieces. Top, M. 2_1, supports PCI-E and SATA devices up to a length of 8 cm and when you install a SATA drive-type disables the port SATA_2.

At the bottom you can only install PCI-E drives up to 11 cm, additionally it is equipped with a plate heat sink with thermal pad.

A total of 17 on-Board USB ports. Eight of them are displayed on the rear panel, where you can find two USB 2.0, two USB 3.1 Gen1, and four USB 3.1 Gen2 (one of the format Type-C). Six USB 2.0 can be connected to two pads on the Board (use an additional hub), in the same way you can display and dual USB 3.1 Gen1. In addition to them, to the Board connects a single USB 3.1 Gen1 for the front panel of the system unit. A very comprehensive set of ports.

As the network controller on ASUS Prime Z390-A widely used common chip Intel I219-V .

 

Hardware protection against static electricity and surge will provide a block of LANGuard and software optimization of traffic it is possible to spend utility Turbo LAN.

The basis of the audio section of the Board is a processor Realtek S1220A with the stated ratio of signal to noise ratio (SNR) on the linear audio output of 120 dB and SNR level on line input – 113 dB.

Such values are achieved including through the use of Japanese capacitors with premium, the breeding left and right channels in different layers of the PCB, insulation audiosony on the PCB from the rest of the elements of the conductive strip.

At the software level supported surround sound technology DTS Headphone:X.

For monitoring and fan control on the Board is provided Nuvoton NCT6798D.

In total, facilities include seven fans, each of which can be configured individually by PWM signal or voltage. There is a separate socket for connection of pump cooling system, outstanding current 3 A.

Connector EXT_FAN is possible to connect an expansion Board with extra connectors for fans and thermal sensors, which then can also be controlled from BIOS.

Setting the automatic overclocking on ASUS Prime Z390-A is implemented by the microcontroller TPU KB3724Q.

To connect to the external tapes of led backlighting, the Board provides two connectors for Aura RGB.

Supported tape length up to three meters. On the PCB Board highlighted area casing exits and a small portion of the radiator of the chipset, and adjusting the illumination color and choice of modes available through the app ASUS Aura.

Other connectors on the bottom edge of the PCB, select the new connector NODE, which can connect the power supply units ASUS for the monitoring of energy consumption and fan speed.

But the lack of an indicator POST-codes on the Board are not happy, even though her mainstream class.

Cooling the VRM circuits Board involved two separate aluminum radiator with pads. In turn, the chipset consumes less than 6 watts, cool small 2-3 mm plate.

The same thickness and the plate to drive in the lower M. 2 port. Moreover, the manufacturer promises a 20-degree decrease in temperature storage in comparison with the indicators at all without the radiator.

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.

GIGABYTE X570 AORUS PRO

GIGABYTE AORUS PRO X570

#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.

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.

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.

#Read more about the characteristics of Ryzen 9 3900X

The review Ryzen 7 3700X we compare it with the older LGA1151-Intel. 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.

Ryzen 5 3600 6/12 3,6 4,2 32 65 CCD + I/O $199

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.
