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.

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.

One of the most basic principles followed AMD in recent years, is: “let’s add more cores”. It was under this motto trace their triumphal procession as desktop processors Ryzen together with their HEDT-brothers Threadripper, and server family of chips EPYC. For clarity, can be more think about the AMD offerings for the mass market, appeared on the market in recent years: in the first generation Ryzen vs Quad core Kaby Lake she put processors with eight cores, then eight Ryzen fought with six-core Coffee Lake, and this year the massacre of osmeterium Coffee Lake Refresh was thrown dwenadzatiperstnuu Ryzen 9 3900X. But the story about how AMD imbued with the idea of Osypandfive users of cores, not the end, because the crown family Ryzen 3000, the company decided to make an even more monstrous processor with sixteen cores.

However, despite the thrust to increase the number of cores at every opportunity, present tactics AMD is still significantly different from how she acted before. If in 2017 and 2018, additional kernel Ryzen acted as a kind of compensation lower than the competitor, specific performance and frequency, with the architecture Zen 2 the “Reds” made up for the lag in the rate of IPC and began to pretend to reshape itself for the whole CPU market. As it turned out four months ago, when the 12-core Ryzen 9 3900X, for the mass AMD with exceptional performance users willing to pay significantly more typical for this market segment $ 500. Far to go behind examples it is not necessary: when problems with the production Ryzen 9 3900X turned into a severe shortage, and the price 12-core model at the peak jumped to $900, buyers it absolutely did not stop – they continued to methodically sweep them from the shelves.

Now AMD wants to eventually become a mass platform Socket AM4 in the higher positioning, proving that she is not forbidden to cost a half times more established years prices. To prove this will be the new flagship Ryzen 9 3950X in which the number of compute cores has increased by a notch to 16. This processor is estimated by the manufacturer at $749, allowing the platform Socket AM4 to make a shameless RAID on the territory HEDT, and judging by what was already known about Ryzen 9 3950X until today, not only to conduct reconnaissance, but also safe to settle there. Confidence in the viability of the new items give its characteristics. With the help of modern technological process TSMC with a 7-nm rules and thanks to innovative capleton design, AMD was able to do so, that the increase in the number of nuclei in 9 Ryzen 3950X is no lower operating frequency, no deterioration of efficiency. As a result, the 16-core flagship needs to prove themselves worthy in the whole spectrum of existing tasks and in demanding multi-threaded workloads can be expected to really breakthrough to the mass segment performance.

In other words, Ryzen 9 3950X, which is dedicated to this review pretends to be a kind of overprotection to mass platforms, which is characterized by the fact that involve the use of dual-channel memory and are limited in the number of supported PCI Express. But here lies the main intrigue of today’s test: when studying the characteristics Ryzen 9 3950X many may feel that the usual common platform is “too much”, it turns out that along with the powerful 16-core manufacturer allows you to install it and dual-core processors-plugs cost from $50. Whether promising Ryzen 9 3950X “spread your wings”, or its potential will be unrealized due to limitations in the bandwidth of the memory subsystem, and power supply? And talk about this further.

#9 3950X Ryzen in detail

From the point of view of topology, a new 16-core Ryzen 9 3950X very similar to the previously reviewed Ryzen 9 3900X. Before us – the second mass AMD processor, which is based not on two but on three semiconductor crystals, called in modern terminology chipsetati. One of these crystals – universal 12-nm chipset cIOD responsible for the functions of the I / o and contains the memory controller, PCI Express controller and elements of the SoC. The other two 7-nm chipley CCD, in which there are processing cores, eight pieces in each. All this is connected together via a bus Infinity Fabric that binds each of the CCD chipsetov c crystal cIOD. At the same time between a CCD mutual relations have not, but it does not entail any negative consequences, because the whole logic of Infinity Fabric is coplete I / o that calls all the cores of rights. In other words, Ryzen 9 3950X, in contrast to multi-core processors Threadripper last generation, has no-NUMA nodes and logical point of view has a completely monolithic design, in which delays in the work memory and with the mutual data exchange is the same for all nuclei.

Read more about how AMD implements mnogochastny approach for the creation of flagship processors Ryzen, we talked in overview 12-core Ryzen 9 3900X. Shestnadtsatiyaderny Ryzen 9 3950X arranged in the same way, but it uses a fully functional crystal CCD, in which there are no locked cores.

It would seem that everything is very simple, and it is unclear just why AMD has not provided Ryzen 9 3950X before, simultaneously with other Socket AM4 processors. However, this delay is a logical explanation. The thing is that getting hands on progressive microarchitecture Zen 2, AMD has set an ambitious goal is not just to bring in mass-market processor with 16 cores, and to do so more effectively. To do this, according to the original plan Ryzen 9 3950X had to not only support a maximum table segment number of threads, and high clock frequency, and to have it all together does not lead to a marked increase heat dissipation and energy consumption.

Mnogochislennoe design allows to solve various problems peculiar to large monolithic crystals, due to the fact that a small area of the chips to produce and easier and cheaper. But direct methods to neutralize the growth of energy consumption and heat dissipation when you add in the additional processor cores, it does not offer. So in the end, AMD took some more time to Ryzen 9 3950X able to acquire the desired characteristics: 16 cores, the maximum in the whole lineup Ryzen third generation turbo frequency, and ordinary for the mass CPU heat pack. This is achieved very easy in the description, but it’s pretty dreary in the implementation method of choice for such processors the most high-quality semiconductor crystals.

In fact, the same approach has been applied in 9 Ryzen 3900X, and in the case of this processor, you can see how difficult it is given to the selection of crystals for CCD tracebility processors, even if then they blocked a quarter of the cores. AMD could not meet the demand and ensure uninterrupted supply of 12-core options for the whole quarter, resulting Ryzen 9 3900X has long been in short supply. You can choose the perfect crystals for Ryzen 9 3950X even more difficult: two full eight full chiplet CCD with crystal cIOD must fit within 105-watt thermal package, while providing approximately the same frequency in the neighborhood of 4.0 GHz at full load, as did the rest of the processor family Ryzen 3000.

Pause, AMD taken, was to allow the company, together with our manufacturing partner, TSMC solid state forge, to optimize the manufacturing process and to form a supply of suitable crystals and order of Ryzen 9 3950X turned real, not paper novelty. But to test how effective was all this preparation, we can only after November 25 – that’s when we will start sales of mass 16-core AMD. In the meantime, we have the opportunity to assess only the performance and nuances of working Ryzen 9 3950X, but I can’t vouch for its wide availability in the sale at the price which he has promised AMD – $749.

Passport characteristics 16-core Ryzen 9 3950X in comparison with other Ryzen third generation is as follows.

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 5 3500X 6/6 3,6 4,1 32 65 CCD + I/O ~$160
Ryzen 5 3500 6/6 3,6 4,1 16 65 CCD + I/O ~$150

Base frequency Ryzen 9 3950X installed in the 3.5 GHz, slightly lower than other processors of the lineup, but the frequency in turbo mode can reach 4.7 GHz and this is the maximum autorange for any Ryzen third generation. The CPU should not go beyond the thermal pack 105 W, that is, to not be hungry and not hot the older model for Socket AM4, which was available until now.

However, to worry about the heat dissipation Ryzen 9 3950X no special reason. Any requirements on thermal and energy performance from AMD are easily implemented through the technology of Precision Boost 2.0, which sets Ryzen 9 3950X the same limits on consumption and currents that were previously installed for Ryzen 9 3900X or even Ryzen 7 3800X. The value of PPT (Power Package Tracking), limiting the actual consumption of the CPU installed in 142 W maximum current consumption for long loads TDC (Thermal Design Current) is limited to 95 a, And at short-term bursts allowed to increase to 140 And this limit lies in the constant EDC (Electrical Design Current). If in real terms the processor tries to go beyond these boundaries, its frequency is forcibly reduced, which determines the frequency formula in reality.

To assess what range can be frequency Ryzen 9 3950X in practice, we carried out a standard experiment – drove popular rendering test Cinebench R20 with different number of threads and recorded the frequency that was observed in each case. The result is the following relationship.

Unfortunately, in reality the frequency Ryzen 9 3950X don’t look so good as you would expect. First, the processor does not issue if a single-threaded load the promised specifications frequency 4.7 GHz. AMD has long struggled with this problem, but for a new 16-core option it POPs up again. Despite the fact that the test for ASRock X570 Taichi is already available BIOS based on the most rasposledny libraries AGESA 1.0.0.4 B, the maximum measured frequency at single-threaded load in Cinebench R20 made up of 4.625 GHz, and the average is 4.6 GHz, that is 100 MHz lower than the declared value.

Second, increasing the number of active threads (and number of cores used), this frequency is quite sharply goes down. For example, when the load on the two cores it drops to 4,475 GHz, and four GHz to 4,325 already. It is obvious that AMD and its partners still have to spend some time to fix endemic problems with the turbo frequencies, but now with a new shestnadcatiletnie.

Also, it should be noted that full load in Cinebench R20 on all cores pushes the CPU frequency significantly below 4-gigagertsevogo strap. Thus Ryzen 9 3950X is the first representative of the family Ryzen third generation, which does not hold up to 4.0 GHz with activity of all cores. At our instance the CPU frequency was 3,875 GHz, while, for example, 12-core Ryzen 9 3900X when rendering in Cinebench R20 could work to 4.05 GHz. A reduction in the frequency occurs in this case due to the fact that Ryzen 9 3950X begins to abut against the prescribed limits on energy consumption. And, obviously, for more complex load than rendering, the situation could easily worsen. For example, in the stress test Prime95 29.8 c AVX instructions frequency Ryzen 9 3950X falls even below the nominal value – up to 3.3 GHz.

The underlying causes of the low frequency Ryzen 9 3950X in multi-threaded loads are about how AMD came to the selection of crystals for such processors. Unfortunately, high-quality crystals CCD, capable of operating at high frequency with moderate tension with moderate heat release are extremely rare. Therefore, in order to secure the release of Ryzen 9 3950X in any appreciable quantities, AMD decided to use the two types of fundamentally different quality of the CCD chipsetov. The principle is simple: the first crystal CCD is responsible for the high frequency in turbo mode, but maybe have large leakage currents and higher power consumption and heat. Second chiplet should offer good energy efficiency: it can not take the high frequencies but its efficiency should be definitely better than the first.

The viability of this scheme in the case of Ryzen 9 3950X is determined by what processors Ryzen third-generation heterogeneous not only physically but also logically. At the stage of production they are distributed priorities, and the task scheduler of the operating system always tries to load the job initially more pliable frequency of the kernel (in Windows 10 it is for example, from version May 2019 Update). As a result, AMD really manages to win, sharing tasks between chipsetati. In particular, the performance of the turbo mode is enough to guarantee only for the elite of successful nuclei from chiplet with good scalability in frequency. The rest of the kernels at a high frame rate never go out and are involved in the calculations only in multi-threaded workloads when processor frequency is much lower.

Says it all very simple to illustrate. The following table shows the maximum achievable cores of our instance Ryzen 9 3950X turbo frequency voltages that are requested by them for the functioning in this mode. These data were obtained in a single-thread test of Cinebench R20 when force direction of the load on different cores. Simultaneously with the observation of frequencies and voltages, we also measured power consumption and the running cores.

Here it is clearly seen that the first chiplet (CCD0) is selected in frequency, significantly outperforming the capabilities of scale-out performance the second chiplet (CCD1). So, the kernel of the first CCD chiplet can work at frequencies above 4,475 GHz, without any voltage over 1,466 V. Maximum frequency of the nuclei of the second chiplet 100-200 MHz worse, but despite this, to operate at maximum frequencies require higher voltages, which can reach 1,481 V. thus the characteristic feature of the second CCD lies in the fact that even at the highest possible rate of its nucleus under load consume less power due to smaller leakage currents.

Differences in the efficiency of CCD and crystals is seen at full CPU load. In this case, all cores operate at the same frequency and with the same voltage, but have different power consumption. Here’s how it looks when rendering in multithreaded Cinebench R20.

Our instance Ryzen 9 3950X consumption of the second chiplet was not much lowerthan the first, but the General principle is still clear: the first CCD-chiplet in the high-frequency processor, and the second is slower, but with reduced energy consumption.

To focus on a detailed analysis of the other characteristics Ryzen 9 3950X we won’t: they are exactly the same as Ryzen 9 3900X. So, the processor has a L3 cache capacity of 64 MB, which consists of four 16-megabyte parts, distributed over four CCX (Core Complex) and also offers 24 PCI Express 4.0, 16 of which are typically allocated on the graphics card, 4 – in NVMe drive and 4 – the connection with the chipset. Read more all this can be seen in the screenshot CPU-Z.

Although Ryzen 9 3950X – processor for conventional mass of the platform Socket AM4 in all your marketing materials AMD clearly indicates that competitors in the ecosystem LGA1151 had not. Mounted on Ryzen 9 3950X price is $749, opposes his proposals for HEDT platform LGA2066. In the official presentation of the new 16-core is called a competitor for the 12-core Core i9-9920X, which according to the official price list costs $1189. But you need to keep in mind that in a few weeks the market will be the Core X ten-thousandth of a series (Cascade Lake-X), the cost of which will be reduced. And soon against Ryzen 9 3950X will be no 12-core and 14-Core nuclear i9-10940X with a suggested price of $784.

As it happens with the performance, we will see, but should bear in mind that Ryzen 9 3950X unlike processors under LGA2066 works with dual channel and not Quad channel DDR4 memory, and also offers twice the PCI Express (but the fourth generation).

#Compatibility issues

Such dramatic changes that occurred this year with the AM4 Socket systems are mind-boggling. But it is doubly surprising that, doubling the number of cores in the older Ryzen series processors, AMD continues to maintain end-to-end compatibility within the entire ecosystem. In other words, the 16-core Ryzen 9 3950X can work in Socket AM4-motherboards released this, the past and even the year before. However, with some reservations.

AMD itself recommends Ryzen 9 3950X motherboard, built on chipset X570, because they usually have more powerful power supply, but this is not essential. Required to work 16-core processor for Socket AM4-boards is just to use a recent firmware: correct and stable operation Ryzen 9 3950X is guaranteed only to those BIOS, which are collected at libraries AGESA 1.0.0.4 B (1.0.0.4 Patch B). For the most common models based on chipsets X570, X470 and B450, the necessary updates should be out before the end of this month, at least in beta versions. At the same time, these updates will again be retouched work of the turbo mode, the maximum practical frequency at which each update systematically closer to their nameplate values.

The second important point concerns the fact that Ryzen 9 3950X is the first representative of the family which will not come with a bundled cooler even in the boxed version. In the range from AMD is simply not found in standard versions of the cooling systems, which could provide a 16-core processor, a sufficient heat sink. Despite the progressive 7-nm chipley and soldered to the crystals heat-dissipating cover, Ryzen 9 3950X needs more efficient cooling than the senior cooler AMD Wraith PRISM. Therefore, AMD decided to shift the question of selection of the cooling system on the shoulders of the user, giving only vague recommendation that for Ryzen 9 3950X requires liquid cooling radiator sizes from 280 mm. in Fairness it should be noted that the very AMD for their marketing materials tested Ryzen 9 3950X air cooler Noctua NH-D15S. Therefore, it is hoped that productive supercooler for Ryzen 9 3950X also quite suitable.

But it must be borne in mind that the algorithm of automatic overclocking Precision when the Boost Override takes care of including a temperature mode of the processor. Therefore, more efficient cooling may be useful for Ryzen 9 3950X the best result.

#Acceleration

Because Ryzen 9 3950X made from two versatile CCD capleton, one of which is not at all about high frequency, overclock the processor a selection of a single fixed frequency for all cores – the idea is strange and, most likely, doomed to failure. However, for the sake of curiosity, we still decided to see how high you can raise the frequency of that CPU, if you act in the forehead.

The best processor family Ryzen 3000 tested in our laboratory, were dispersed simultaneously on all cores to 4.3 GHz. Shestnadtsatiyaderny Ryzen 9 3950X this record was not broken for at least two reasons. First, due to high heat dissipation. Three nearby semiconductor crystal will always be heated stronger of the two, and therefore, despite the use of the test environment, the productive liquid cooling system NZXT Kraken X72, high temperatures became a serious obstacle. Secondly, we should not forget about the second CCD-ciple, which Ryzen 9 3950X selected with a view to lower dissipation, which in some cases is converted into a considerably worse frequency potential.

Ultimately, the maximum frequency at which it was able to work steadily Ryzen 9 3950X under high load on all cores, was at 4.1 GHz. At a supply voltage of 1.2 V the CPU is held on this frequency hour test in Prime95 29.8 c active AVX2 instructions.

It should be noted that approximately the same results were obtained when overclocking Ryzen 9 3900X, from which we can conclude that trickipedia processors do not tolerate the simultaneous rise in the frequency of all cores at once. Indeed, the final frequency the simplest approach to overclocking is much lower than the maximum frequency in turbo mode, giving a clear hint that no need to do so.

The correct method is the use of a Precision Boost Overdrive function, which allows you to remove all the inherent limitations on CPU consumption and its supply currents. In this case, left to itself, the CPU alone will reach those milestones, which will be determined by the quality of its silicon chip and the capacity of the applied cooling system. A huge advantage to overclocking through Precision Boost Overdrive is that this function leaves active opportunistic algorithms-locked loop, and the CPU stores the variability of the frequency depending on the load. And therefore the CPU frequency at low load after the dispersal will be at least no worse than in the nominal mode.

However, when you enable Precision Boost Overdrive test Ryzen 9 3950X proved himself as a typical representative of the series. AMD itself almost to the limit dispersed a 16-core, leaving for experiments users quite a bit of space. Under single-threaded load in Cinebench R20 CPU increased the frequency of only 25 MHz to 4.65 GHz.

But in a multithreaded load frequency Ryzen 9 3950X enabled Precision Boost Overdrive increased by 125 MHz to 4.0 GHz.

Of course, the meaningfulness of such a crackdown raises serious doubts: in the best case, it can raise performance by 1-3 %. But this result is not yet final. We must not forget that while Ryzen 9 3950X does not develop the required frequencies even in the nominal mode, so as soon as AMD and partners will make changes in the motherboard BIOS, the effectiveness of Precision Boost Overdrive can also rise.

The whole story of the appearance on the market of Core i9-9900KS from its very beginning made us feel deja vu. Why? It’s very simple, similar events we found sixteen years ago, when AMD released its revolutionary Athlon 64 and Athlon 64 FX to a class of Hammer. Then, to repel these innovations, Intel urgently organized the release is equipped with 2 MB L3-cache of the Pentium 4 Extreme Edition, hastily converted from a server chip Xeon MP. Now, of course, the situation is somewhat different scenario, but the General plot outline remains the same. Without the ability to symmetrically respond to the daring encroachments of rival, Intel gets out as he can and instead of the new product family offers temporary flagship processors “rapid response”.

Core i9-9900KS is such made from scrap materials response Ryzen third generation. Remember, the announcement of the impending release of the Intel CPU made in early June at Computex – just a few days before the announcement Ryzen 3000. The significance of this step was easily guessed is just that, at which point it was made, because in reality, the Core i9-9900KS made it to the market only a few months in November. At that, what about Core i9-9900KS would have to say so far in advance, there is is a slightly overclocked version of OCTA-core Core i9-9900K, which in reality should be the main trump card of Intel only for the next few weeks, high pre-Christmas demand.

A full answer to Intel Ryzen 3000 we will see soon enough. Issue 10-core processors in Comet Lake is scheduled for the first quarter of 2020. But if you want to put new Intel under the tree, the content will be Core i9-9900KS. However, do not think that it would be something like a “consolation” gift. Intel about skromnosti says about Core i9-9900KS this: “based on the Core i9-9900K, we made the world’s best gaming CPU is even better, “and it seems to be true.

Translated to marketing, this thesis means that received in the sale of Core i9-9900KS is a special version of the Core i9-9900K, built on selected semiconductor crystals, able to work at even higher clock frequencies. Moreover, the “special” literally: letter S that appeared in the end of the model number – it is short for Special Edition. Formal specs are such that Core i9-9900KS able to work on “beautiful” 5.0 GHz with simultaneous load on all eight cores. Confuses only one: the warranty period of such accelerated processor is limited to one year, while on a conventional Core i9-9900K (in single package) is given a three-year warranty.

The exclusivity of the Core i9-9900KS manufacturer underlines with a story that, for the manufacture of such a CPU it has to use a special procedure for the selection of semiconductor chips, causing the circulation of such processors becomes quite small. What specific number of “special” chips will be put on the market not reported, but you can be sure that in the next year to buy a Core i9-9900KS in the store will be problematic. This is due in part to the fact that the margin for the tab for the Special Edition and 5-GHz frequency is not so large and not able to become a major obstacle for buyers. The recommended price of the Core i9-9900KS — $513 for just $25 more than the cost of conventional Core i9-9900K.

However, the question of whether or not to chase it for a Core i9-9900KS, still remains, and the answer is we will try in this review in which we compare the new Intel with available alternatives from the same price category, among which the most interesting is not even the usual Core i9-9900K, and 12-core AMD Ryzen 9 3900X.

#Read more about Core i9-9900KS

Core i9-9900KS was the fifth member of the family Coffee Lake Refresh received model number 9900. His colleagues have always offered eight cores with support for Hyper-Threading technology and had a 16-megabyte L3-cache, but differed thermal package, with overclocking potential, the target frequencies and the presence or absence of the integrated graphics core. At the Core i9-9900KS as the culmination of the evolution of the ninth generation Core, all of these characteristics are unscrewed on a maximum value, but when matching with a previously released related processors, formal specification of Core i9-9900KS imagination does not impress.

Price $513 $488 $463 $439 $439

Imposing this table looks, except the calculated dissipation Core i9-9900KS — 127 watts. However, among the mass of processors there have been instances and hotter enough to remember, for example, about Intel Core 2 Extreme or AMD FX Black Edition thousandth series.

More high than the other 9900, the base frequency of the Core i9-9900KS absolutely nothing. First, as we know it, Intel never really work, and the real frequency determines the aggressiveness of the technology Turbo Boost 2.0. Second, the growth of the base frequency is a direct result of raising the heat of the package, because under the current wording, TDP just is defined as the dissipation of the processor at nominal base frequency.

Therefore, in order to assess the uniqueness of Core i9-9900KS fully, you need to look deeper, up to the maximum achievable within the turbo mode frequency when the load on different number of cores. It’s funny that recently Intel decided to remove information about the value of open access, and now the company is faced with the fact that this was done completely in vain, because without this advantage, Core i9-9900KS not to show it. However, with some patience the value of turbo frequencies can be ascertained experimentally or by using diagnostic utilities.

And only in this case the advantages of Core i9-9900KS become clearer: when the load on the six and more cores that the processor is allowed to operate at 300 MHz or 6.3% faster than Core i9-9900K and Core i9-9900KF.

  Base frequency, MHz Maximum frequency in turbo mode, MHz
8 cores 7 cores 6 cores 5 cores 4 cores 3 core 2 cores 1 core
Core i9-9900KS 4,0 5,0 5,0 5,0 5,0 5,0 5,0 5,0 5,0
Core i9-9900K 3,6 4,7 4,7 4,7 4,8 4,8 4,9 5,0 5,0
Core i9-9900KF 3,6 4,7 4,7 4,7 4,8 4,8 4,9 5,0 5,0
Core i9-9900 3,1 4,6 4,7 4,7 4,8 4,8 4,9 5,0 5,0
Core i9-9900T 2,1 3,6 3,8 3,9 4,0 4,1 4,2 4,3 4,4

In fact, however, all this does not mean that by selecting Core i9-9900KS for your system, you will get 5.0 GHz at any load. Don’t forget that the turbo frequency is the maximum autorange, which is possible, but not guaranteed. The Turbo Boost technology 2.0 automatically increases CPU frequency not just on the basis of the number of operating cores, and taking into account other parameters, in particular, the nature of the load and, most importantly, caused by her consumption. The theory of sets of power consumption of the processor in turbo mode two limit values PL1 and PL2, which limits its short-term and long-term loads. Limit PL2, specifies the maximum consumption for long time intervals, is assumed to be the nameplate value TDP. The same limit PL1 is typically set to one quarter above PL2, allowing the processor to consume more than laid down in TDP, but only for small periods of time. Limit the duration of such time intervals is defined by the constant τ, which, according to the specification, can be selected in the range from 1 to 8 seconds.

All this means that when designing the Core i9-9900KS was laid, that he will consume no more than 127 watts when used for long periods and not more than 159 W for short. And consumption limits with a 5-gigagertsevogo frequency is clearly incompatible. For example, even Core i9-9900K at its turbo frequency of 4.7 GHz in multithreaded rendering in Cinebench R20 consumes around 195 watts. The new Core i9-9900KS at a frequency of 5.0 GHz in this test shows a consumption of about 220 watts.

So if all was fair and in accordance with the specification, it would be no 5.0 GHz we would not have seen even close. The following chart illustrates this, where we have built a frequency curve Core i9-9900KS depending on the load in Cinebench R20, built upon the work of the CPU with the correct limits PL1 and PL2 mounted to 127 and 159 watts. Immediately given, and a similar curve for Core i9-9900K, which are the limits in accordance with the specification set to a quarter lower at 95 watts and 119 watts.

Although Core i9-9900KS and operates with significantly higher frequency compared to Core i9-9900K, about any 5 GHz under full load it still is not. This frequency can be observed if the number of busy threads does not exceed six, and no more. Maximum load in the multi-threaded Cinebench R20 cuts the frequency of Core i9-9900KS to 4.5 GHz due to the fact that silicon Coffee Lake Refresh, produced by 14-nm technology, crossing the line in the 4.4-4.5 GHz is always sharply increasing energy appetite.

However, all of these concerning the frequency of surveys is interesting theoretically, because motherboard manufacturers with the tacit consent of Intel simply ignore the limits PL1 and PL2, setting them to maximum. To meet some meaningful setting these limits is possible only on low-cost motherboards with weak power, the overwhelming majority of Z390 platforms the default is twisting these limitations in maximum and obviously unattainable values. And that’s why reducing the frequency with the growth of power consumption within specification TDP in reality, Intel is not observed.

Until now, such a liberal attitude to power settings went Intel and motherboard makers with it. Everyone was happy, because the users eventually received while not as economical as stated in the specifications, but automatically overclock to the maximum turbo mode frequency of the system with improved performance.

But the Core i9-9900KS this focus takes place with difficulty. Operating at a frequency of 5.0 GHz, this CPU produces so much heat that can deal with it only selected cooling system. For example, during testing of our copy Core i9-9900KS we are faced with the failure of our usual air supercooler Noctua NH-U14S and NH-D15. And with a one-body and two-piece tower CPU when running Prime95 29.8 quickly reached the limit temperature of 115 degrees and sinking into the throttle. To achieve stable operation Core i9-9900KS at a frequency of 5.0 GHz in any program, without exception, was possible only after the transition to liquid cooling. Not aby what, and one of the most effective LSS closed loop NZXT Kraken X72, which includes a 360-mm radiator.

NZXT Kraken X72

But even with such a powerful DLC the CPU temperature during the tests reached values of 108 degrees, which, however, is natural, given the 275-watt power Core i9-9900KS under heavy load, seasoned with AVX2 instructions.

All this means that the owners of the Core i9-9900KS unprepared cooling this processor properly, you can easily deal with temperature was throttling, even if they are armed with quite a powerful cooling system and will not overclock it. We are confident that soon the forums and groups in social networks will be swamped with complaints about overheating Core i9-9900KS with the default settings. From Intel there is only one way to avoid this: how to negotiate with producers of motherboards, that at least in the case of Core i9-9900KS they didn’t ignore setting consumption limits.

Of course, you need to keep in mind that we checked the temperature in Prime95 29.8 program, very much warming the processors search for the Mersenne numbers. Such heating occurs in the common problems not so often, but, for example, a high risk of overheating is, in the transcoding of video content modern encoders or rendering. Therefore, by setting the system Core i9-9900KS, better some time to devote to checking temperature and setting it up. We would recommend either to manually pick the consumption limits PL1 and PL2, or set down amendment to the frequency when using AVX instructions, or try to reduce the voltage. And the stories about the 5.0 GHz out of the box always and everywhere do not need to believe: this is hyperbole (literary exaggeration).

Here there is a reasonable question, and it better Core i9-9900KS than Core i9-9900K, if the 25-dollar overpayments for this CPU ensures no overheating to 5.0 GHz and also inevitably dooms the user to careful selection of cooling and additional configuration of the system? But the answer is still positive. As a minimum, Core i9-9900KS really based on selected crystal Lake Coffee Refresh, resulting in slightly lower temperatures and consumption at the same frequency and voltage. For example, we compared the thermal and power characteristics at our disposal copies of Core i9-9900KS and Core i9-9900K at a frequency of 4.7 GHz at a voltage of 1.25 V with liquid cooling system NZXT Kraken X72. And as can be seen from the results obtained when running a stress test like Prime95, Core i9-9900KS really is ceteris paribus more efficient and colder.

4.7 GHz, 1.25 V The maximum temperature Maximum consumption
Core i9-9900KS 86°C 218 W
Core i9-9900K 90°C 226 W

In addition, the Intel Core i9-9900KS, in contrast to Core i9-9900K and Core i9-9900KF guaranteed based on semiconducting crystals of R0 stepping CPU. This means that they have appeared hardware patches for some high-profile vulnerabilities, in particular Fallout and the Spectre V4 (Speculative Store Bypass). However, from a practical point of view it means not too much. Hardware fixes, like their software counterparts, about the same performance impact, and, ultimately, users of Core i9-9900KS did not win, except for the lack of the need to update the firmware and install critical operating system updates and software.

#Acceleration

Given how heated Core i9-9900KS when working in nominal mode at 5.0 GHz, to expect from him some of the feats of acceleration would be weird. However, to achieve higher frequencies, overclockers can use special spare tool that helps with overclocking HEDT-Core processors, X-series. Namely, the limit frequency when operating the CPU with AVX instructions.

That in the case of Core i9-9900KS it can have a positive impact on the result, he says, for example, that resort to it all the foreign shops offering samples of Core i9-9900KS with a guarantee of overclocking. And Caseking.deand SiliconLottery.com when you sort processor share reduction amendment -2 or -3 for the coefficient of multiplication when working with AVX instructions.

But it did not help. Our copy Core i9-9900KS could not ensure stability at the frequency of 5.1 GHz when working with resource-consuming programs, even if they did not use AVX instructions. In other words, the processor was actually, without any overclocking potential, 5.0 GHz – his ceiling.

However, to be surprised about this absolutely should not be. We are dealing with already pre-overclocked factory CPU that was selected among the usual Core i9-9900K just on the principle of performance at 5.0 GHz. And if its overclocking potential would allow to take a more distant frontiers, Intel probably would have used it to improve the performance of its proposal, because it is not a mass product, but on a special limited-edition series of processors.

In fact, all this is well corroborated by the results of the selection of the most successful representatives of family Core i9-9900KS, which is conducted by specialists of the store SiliconLottery.com. Collected them according to the statistics dispersed on 5.0 GHz only one of the three copies of Core i9-9900KS. And we obviously “happy” chip this time not got.

Hardly anyone would argue with the fact that the processors Ryzen 3000 could significantly strengthen the position of AMD in the desktop segment. “Thank you” for this is to say microarchitecture Zen 2, which was much better than the Zen and Zen+ used in processors Ryzen before. The increase in specific productivity in Zen 2 noticeable 15% in the aggregate 5% increase in clock frequency,is provided with a 7-nm process technology, doubling the capacity of the cache memory of the third level and double extension block floating point operations gave an undeniable synergistic effect. As a result, processors Ryzen first and second generations, which until recently seemed pretty good options for desktop systems, now permanently dropped to the second League, speaking on background Ryzen 3000 exclusively in the role of “poor relatives”. Yes there past Ryzen, new members of the family is now possible even in a fair number of cases, to flout the actual mass Intel processors, offering at comparable price the best computational performance.

Illustrates that giant leap forward, which could make AMD, the situation with prices Ryzen different generations: the flagship CPU microarchitecture Zen+, Ryzen 7 2700X, now sold for $190, that is cheaper one of the youngest media micro Zen 2, Ryzen 5 3600. It turns out that the invisible hand of the market quickly pushed all of Ryzen the first and second generations, the solution below the average level, while the upper market segments were completely at the mercy of members of the family Ryzen 3000.

In fact, it is for this reason AMD did not release based on the microarchitecture Zen 2 processors priced below $200 – the emergence of such models would not allow her to sell the chips to past generations, which stocks in the warehouses of the company, obviously, is far from depletion. So do not expect that in the foreseeable future the market will be cheap Ryzen members of the series 3000, which, for example, to the class Ryzen 3. Strap the entrance to the club owners, the media micro Zen 2 will remain at a high level for a long time.

But even the strictest rules there are exceptions, and the situation with the new Junior model Ryzen 3000 – a case in point. The fact that AMD is a flexible company that continually analyzes market conditions and are ready to quickly make targeted decisions to strengthen their positions. In the result of this analysis, it was observed that in some regions a very high popular six-core processor-level Intel Core i5-9400 and i5-9400Fthat many users are willing to choose as the basis for a relatively inexpensive gaming builds. Among the current proposals like AMD for the price and gaming performance options initially was not provided, leading to loss of company of a certain share of the market.

AMD quickly realized that to resolve this situation it is necessary to release a slightly more affordable model Ryzen 3000, which would be an alternative to the Junior Intel shestiyaderny and pulled on his interest buyers cheap gaming PC. But in order not to undermine the implementation channel Ryzen past generations, to sell the Junior processors Ryzen 3000, it was decided not globally, but only in those countries where the popular Core i5-9400 and i5-9400F is really high. “Tricky” models, selectively opposed to the younger versions of the Core i5, steel Ryzen Ryzen 5 3500X 3500 and 5, as well as their target audience has been selected, users from China, Russia and some Eastern European countries, where demand has historically shifted towards cheaper models of CPU. And it could work: on the one hand, Ryzen Ryzen 5 3500X 3500 and 5 got the value of $150, allowing them to make Core i5-9400 and i5-9400F in one market segment, and on the other they have six cores Zen 2, providing a quite competitive level of performance, at least at first glance.

However, Ryzen Ryzen 5 and 5 3500X 3500 still differ markedly from the more expensive six-core processors Ryzen Ryzen 3600X and 5 5 3600. In their regional AMD chips shut off the SMT technology, that is, each core Ryzen Ryzen 5 and 5 3500X 3500 can perform only one and not a pair of computing threads. But their juxtaposition against the Core i5-9400 and i5-9400F it absolutely doesn’t, because six-core Intel processors also do not support Hyper-Threading. As for the difference between Ryzen Ryzen 5 3500X 3500 and 5, it is not too obvious and is not in clock frequencies, and the size of the cache memory of the third level: the Junior model L3-cache is reduced from 32 to 16 MB.

AMD’s original plan was to offer Ryzen 5 3500X in the Chinese market, and Ryzen 5 3500 in Russia. But in reality, domestic users are luckier because they can get their hands on as he and another processor. In particular, Ryzen 5 3500 gradually appears on the Windows of the large computer shops, while Ryzen 5 3500X you can buy on Aliexpress. As such, we felt duty-bound to conduct detailed testing of both processors in order to establish whether it was true, they can be considered a good alternative to Core i5-9400 and i5-9400F; how their performance is worse than the usual 5 shestiyaderny Ryzen Ryzen 5 and 3600X 3600; and whether it is necessary to deal with these artificially reduced native architecture Zen 2, when for the same or even less you can buy some of the full Ryzen processors of the previous generation.

#5 about Ryzen Ryzen 3500X 3500 and 5 more

With the advent of processors under Ryzen 5 3600 model number desktop media micro Zen 2 was better.

Ryzen 5 3500 6/6 3,6 4,1 16 65 CCD + I/O ~$155

Immediately evident that Ryzen Ryzen 5 3500X 3500 and 5 look at the background of Ryzen Ryzen 5 and 3600X 3600 5 somewhat alien. Senior and Junior model class Ryzen 5 close clock frequencies, but they have different nuclear formula. Although all of these processors – shestiyaderny in Ryzen Ryzen 5 and 5 3500X 3500 number of simultaneously executed threads is six, i.e. twice less than in 5 and 3600X Ryzen Ryzen 5 3600. Generally, users Ryzen for such a serious distinction of characteristics within the same class of processors is already accustomed to. For example, in the past generation of processors under the brand Ryzen 5 AMD offered at the same time and six-core and Quad-core CPU. Now the number of cores different Ryzen 5 remained the same, but in the younger members of the series of disconnected technology SMT (Simultaneous Multithreading), which previously were blocked by the manufacturer solely in the processor class Ryzen 3.

And it would be a quite normal approach for differentiating one class if he didn’t break the whole paradigm of AMD. Still the basis of the company’s strategy in the consumer market were to offer users the best possibilities of multi-threading compared to Intel in the same price category. New Ryzen Ryzen 5 3500X 3500 and 5 for the number of cores and threads fully on par with the Core i5 processors. However, this does not mean that AMD did a kind of “analogue Core i5-9400F” the microarchitecture Zen 2. In fact, considering the novelty is still superior to Intel processors for a number specification.

Speaking about the merits of Ryzen Ryzen 5 and 5 3500X 3500, AMD can focus on two things. First, younger Ryzen 5 compared to the Core i5 have more volume L3 cache, which is not inferior cache in the third level Refresh Coffee Lake from the point of view of latency. Moreover, this is true not only for Chinese Ryzen 5 3500X with a 32-megabyte L3-cache, but even for Russian Ryzen 5 3500, despite the fact that most affordable modification Ryzen 5 cache memory is reduced in volume by half.

Second, the AMD processors support faster memory. Formally, we are talking about DDR4-3200, but in fact Ryzen Ryzen 5 and 5 3500X 3500, like any other mass AMD processors based on the microarchitecture Zen 2 is compatible with faster memory, up to DDR4-3600. Moreover, due to improvements in Ryzen third generation memory controller, high-speed DDR4 SDRAM can be used in all motherboards, including those based on older chipsets X470, even B450 and B350. At the same time, for Intel Core i5-9400 and Core i5-9400F in the specs the performance is declared only with DDR4-2666. In part, this condition is also formally: if the Core i5 processor installed in the motherboard the chipset Z370 or Z390, the memory can operate at arbitrarily high frequencies – this is no problem. However, in low-cost platforms using chipsets H370, B360 (B365) or H310 specifications and the limitation starts to play a role in such cases to operate the memory with a higher than DDR4-2666 frequency will not work.

We should also mention the clock frequency. Although advertised for 5 Ryzen Ryzen 5 and 3500X 3500 base frequency values substantially higher than the Core i5-9400 and i5-9400F, in reality, all these processors are operating at the same frequency. Turbo mode in Core i5-9400 and Core i5-9400F even load on all six cores keep them running at 3.9 GHz, about the same frequency you can see at full load and at Ryzen Ryzen 5 or 5 3500X 3500.

As seen in the screenshots, and 5 3500X Ryzen, Ryzen 5 and 3500 under load on all cores develop the frequency of 3.95 GHz. And this is about 100-150 MHz below the frequency at which full load working shestiyaderny AMD higher class Ryzen Ryzen 5 and 3600X 3600 5, although younger shestiyaderny and stated exactly the same base frequency as for Ryzen 5 3600.

Speed L3 cache and the memory subsystem in the Junior six-core Ryzen there are no surprises. Despite the fact that Ryzen Ryzen 5 3500X 3500 and 5 differ dramatically in the amount of L3 cache, it is his capacity, not bandwidth or latency is a major cause of the difference in their performance. That is, a full-sized 32-magarity and trimmed the 16-megabyte L3-cache in this processor offers approximately the same performance.

However, with the synthetic CacheMem test from the Aida64 package to notice some differences in bandwidth and latency path is still possible. The cache is a smaller size Ryzen 5 3500 slightly faster than the full-size version, but at the same time at the speed of memory operation is a small the advantage is over Ryzen 5 3500X with full L3-cache capacity of 32 MB. However, the differences are in any case unimportant: if we talk about latency, it is no more than two bars.

The apparent lack of differences between Ryzen Ryzen 5 3500X 3500 and 5 is not surprising. These processors are based on the same silicon basis, common to all desktop AMD offerings to a class of Zen 2 and the number of cores not more than eight. Both CPU are under the CPU cover, two semiconductor crystal, one of which is the standard eight-core 7-nm crystal CCD, and the second on 12-nm crystal cIOD that contains the memory controller, the logical part of the tire Infinity Fabric and elements of the SoC. Lock for the considered models Ryzen 5 two “extra” cores and SMT technology, as truncating the cache Ryzen 5 3500 runs at the production stage logically, however, the possibility of restoring lost characteristics by the user hope not. The last time unlocking cores and cache, AMD has allowed the processors of the Phenom, and it was a very long time. In addition, you need to understand that processors like Ryzen Ryzen 5 and 5 3500X 3500 convenient for the manufacturer so that they can be widely applied in the sorting of partially inoperative semiconductor crystals with defects of single cores or cache.

#Acceleration

We usually say that the overclocking Ryzen third generation is deprived practical sense: the manufacturer its technology Autonomous dynamic overclocking Precision Boost 2.0 already squeezed them dry. However, the nominal clock frequency Ryzen Ryzen 5 3500X 3500 and 5 are somewhat lower than more expensive counterparts, even in comparison with other shestidennomu. For example, Ryzen 5 3600X under load on all cores running at a frequency of about 4.1 GHz, and for 5 and 3500X Ryzen Ryzen 5 3500 that is the limit in turbo mode.

So deliberately expunged from consideration overclocking potential, referring to its insignificance, we will not. Moreover, the possibility of increasing the frequency above the rated values is another competitive plus Ryzen Ryzen 5 and 5 3500X 3500 in the fight against the Core i5-9400 and i5-9400F, which surely will be remembered as in advertising and in online discussions. And it’s true: the younger shestiyaderny Intel is certainly not dispersed, and all processors Ryzen, including today’s heroes, have a free multiplier, which gives a chance to further improve performance.

However, as shown, to a noticeable acceleration of the Junior shestiyaderny better not to hope. These processors can get quite “weak” semiconductor crystals capable of stable operation only in the neighborhood of the nominal clock frequency. So it was that we were able to sample Chinese Ryzen 5 3500X. It is with great difficulty mastered the frequency is increased to 4.05 GHz, which required to raise its voltage to 1.4 V – level, which is the case if acceleration is planned to be used constantly, is “on the verge”.

At higher frequencies the processor is not passed the stability check, which we traditionally hold in 29.8 Prime95 in Small FFT mode with enabled AVX instructions. But even at the relatively low frequency of 4.05 GHz heating during tests reached 86 degrees with that cooling system using a productive cooler Noctua NH-U14S.

But the second CPU, the Russian Ryzen 5 3500, by contrast, turned out to be overclocking very malleable. It easily managed to bring the frequency to 4.3 GHz, but this record acceleration for all tested until now, members of the family Ryzen 3000. Moreover, to ensure the stable operation of Ryzen 5 3500 at this frequency does not even require a particularly strong bully of his food. No stability issues have not arisen when choosing a voltage of 1.35 V.

Temperature Ryzen 5 3500 under load with the cooler Noctua NH-U14S reached 90 degrees, but we have long been accustomed that the 7-nm processors AMD hot chips. In addition, based on overclocking results, we can conclude that the inherited instance CPU has a fairly high leakage currents.

If you compile two fundamentally different result of dispersal Ryzen Ryzen 5 3500X 3500 and 5, we can conclude that in these AMD processors can use much different in quality of semiconductor crystals. They can get as second grade who couldn’t find use processors with higher clock frequencies and very good in the sense of the frequency potential of the chip. Here could be as lucky, so that cheap shestiyadernik can significantly disperse, it is better not to rely on.

The point here is in the fact that all of the model series 3000 Ryzen in fact designed to work about the same clock frequency in the neighborhood of 4.0-4.2 GHz. For the differentiation of varieties of AMD relies on other features – the number of cores, TDP and now the SMT technology and the size of the cache memory. Therefore the usual principle that the younger the processors is almost always possible to disperse the frequency to the level of a senior in this case means almost nothing. Acceleration of any Ryzen 3000, especially one that is not using the function Precision Boost Override, and synchronous across all cores, can bring performance improvements at best only a few percent.
