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

As you probably remember, along with the processors Ryzen second generation (Pinnacle Ridge), AMD introduced a new chipset X470, thereby enabling motherboard manufacturers to bring to market an updated flagship Socket AM4 platform. And this really makes sense: the design boards on the previous chipset for the older Ryzen, X370, often left much to be desired. Most of these products were designed prior to the release of the first processor microarchitecture Zen, and at that time few believed that the new solution from AMD will be so good that I can seriously compete with intelocking CPU. This had an impact on the approach to the design: even among platforms based on the older Socket AM4-chipset X370 many of them contain certain compromises that are not too feature-rich and does not seem to be the flagship platforms.

X470 should solve the issue. That is capable of AMD Ryzen, it is now understood very well, so motherboard manufacturers can, without fear, to create a fancy and expensive platform. That the demand for them will, no doubt. This wave appeared a lot of new solutions, and almost all of such charges compared to their predecessors, used chipset X370, do differ markedly improved characteristics.

However, the very core of this transformation of the flagship boards in the new chipset X470 did almost nothing. If we compare the characteristics of the chipsets X470 and X370, it appears that support PCI Express, SATA, and USB ports, they are absolutely identical.

  Acceleration XFR2 /PB2 GPU USB 3.1 Gen2 USB 3.0 USB 2.0 PCIe 3.0 PCIe 2.0 SATA RAID StoreMI

A320 No No x16 1 2 6 0 4 6 Yes No

* Support XFRPrecision 2 and Boost 2 is added to c with BIOS updates

In fact, the only significant hardware change X470 compared to the predecessor was the reduction of energy consumption from 6.8 to 4.8 W at full load. Curiously, this has been achieved without any modification of process technology: a new X470 is made at TSMC on the same 55-nm technology as the X370. Helped exclusively the redesign of the power infrastructure of the chip.

Two small innovations were added to the software level. First, X470 appeared StoreMI technology that allows you to compile in a single volume high-speed SSD (any type) and bulk HDD, a single hybrid data warehouse with high speed and capacity. Second, characteristic for processors Ryzen two thousandth series technologies Precision Boost 2, XFR2, according to official information, originally only work in motherboards based on the new chipset.

All these innovations can hardly be called fundamental. The decrease in heat dissipation of the chipset on a few watts in a desktop PC will generally imperceptible; StoreMI – only malofontannaya function; and support for Precision Boost 2, XFR2 is important only where the CPU is running without overclocking, and even then, the performance gains provided by these technologies, not too noticeable. In addition, in recent versions of firmware support for these technologies appeared in motherboards based on chipset X370. And this means that the difference in fees on the basis of the X470 and X370 is for the most part only the result of experience, and the changed attitude to the platform on the part of engineers.

In this article we will focus on the new X470-Board top-level company ASUS – Crosshair VII Hero (WiFi/ac), which just serves to illustrate the above. At first glance, it is almost the same as the last Board Crosshair VI Hero on the basis of the X370, but more detailed acquaintance emerge differences, minor that does not name.

A new Board has better power subsystem, which is now involved not 10, and 12 phases. In addition to fees added asynchronous mode overclocking the base clock generator, allowing to supply to processor cores, DRAM Infinity Fabric and different values of the BCLK frequency. Changes were made in the monitoring of voltages, which now became more accurate. A number of innovations is in the UEFI BIOS. For example, ASUS engineers have implemented new technology-based Precision Boost the acceleration system Performance Enhancer and also could make for Crosshair VII Hero Stealth mode completely turns off all illumination.

In other words, the scale (and not) changes sufficiently, and in order to get familiar with them, we did this review.

Motherboard ASUS Crosshair VII Hero represented on store shelves in two versions – with built-in Wi-Fi-controller and without it. Version WiFi/ac has a recommended price of $300, and the version without wireless support is $20 cheaper. While a similar fee on the basis of chipset X370, Crosshair VI Hero, is now sold a cheaper new for $40. From this we can conclude that the transition to a X470, indeed, involve some appreciation of the platform Socket AM4.

#Packaging equipment

As befits a luxury product series Republic of Gamers, the new ASUS ROG Crosshair VI Hero comes in at the same time bright and simply decorated box. The front side of the box contains only the name of the series, model and a brief enumeration of supported technologies in the form of large icons.

On the back of the box provides detailed Board specifications, private labels marked its merits, and lists the inputs and outputs on the interface panel. On the sticker from one side of the box you can find the serial number and a short list of characteristics.

Inside the main package are inserted two flat boxes, one of which bears the fee, additionally covered with a plastic lid with clamps, and other parts and accessories.

Along with the cost supplied four SATA cables with latches, two screw fastening the M. 2 modules, hard connective HB-bridge for SLI, the connector for connecting the cables of the system case unit Q-Connector, two extension cable to tapes, external lighting and Wi-Fi dual-band 2T2R antenna.

Also included in the kit instruction manual and DVD with drivers and utilities, and as a bonus there is a whole array of stickers of different types and purposes.

Fee is manufactured in China, and it is a three-year warranty. Allotted for the test instance ASUS ROG Crosshair VII Hero (WiFi/ac) refers to version 1.02. In Russia this model can be purchased for the price of 20 thousand rubles.

#Design and features

The ROG series is developed by ASUS since 2006, and throughout this time, the producer pays great attention to how its constituent motherboard look like. In Crosshair ROG VII Hero (WiFi/ac) evolution came down to the fact that the Board has acquired the most “dark” design: PCB slots, heat sinks, casing in the back – everything is black, which interrupt only the gray labels on the PCB and the decorative stripes on the radiators. Develops dark skin and a new mode of operation decorative lighting – Stealth Mode, in which the Board owner can turn off all the glowing elements: not only RGB illumination, but also numerous diagnostic or informational led.

Fans of the unicorns, by contrast, is addressed to the backlit RGB-insert in a protective casing back of the card, and the glowing ROG logo in the chipset. In addition to this Crosshair VII Hero (WiFi/ac) allows you to connect four RGB strips: two regular and two addressable. Algorithms of all this illumination, as usual, are configured through specialized software ASUS Aura.

Crosshair ROG VII Hero (WiFi/ac) has a standard form factor ATX size 305 × 244 mm. I Must say that this Board is just Packed with various components. The possibilities are very rich, and for their implementation of only one chip AMD X470 and on-chip SoC is not enough, so ASUS engineers had to resort to using a large number of additional controllers. However, the typical format they come out, and moreover, the surroundings of the CPU socket on the motherboard was quite a lot of space, making Crosshair ROG VII Hero (WiFi/ac) is convenient in practical use in a traditional enclosure and the stand.

The reverse side of the Board for the most part free of any elements. She made only some of the control components of the power circuit of the processor.

The fact that the charge is among the flagship products for overclockers and gamers, clearly visible on the vehicle its rear panel. In addition to the usual things on it there are two buttons to reset the settings of UEFI BIOS and forced flashing, and even such Exotica as the PS/2 port to connect a mouse or keyboard. In addition, there are two Wi-Fi antenna output, two USB 2.0 ports, eight USB 3.0 ports, one USB port 3.1 Gen2 performance of Type-A and Type-C plug socket for connection Gigabit network, S/PDIF output and a set of five gold plated analog audio jacks. The rear panel ROG Crosshair VII Hero (WiFi/ac) supplied from the preset panel I/O Shield, which significantly simplifies the system Assembly in the housing.

Please note: under consideration Board has no display outputs. This means that even when the Raven Ridge processors with integrated graphics, it will take a discrete graphics card.

One of the main differences ASUS ROG Crosshair VII Hero (WiFi/ac) from its predecessor (Crosshair VI Hero) concerns the allocation of lines PCI Express slots. On the new Board has three PCIe x16 slots where the first pair is controlled by a processor and can run at x16/x0 or x8/x8 while the third slot refers to the chipset. So he could only offer mode PCI Express 2.0 x4, and mechanical boost SafeSlots to effectively withstand the loads encountered during installation of heavy graphics cards with only the first two PCIe x16 slots.

Also the Board has two M. 2 connectors, which claimed to support PCI Express 3.0 x4 drives. Both these slots are to the CPU, but differ in their implementation. Slot, rests against the processor, and an indoor brand of radiator, divides the line graphic bus. So installing it on the drive causes the CPU PCIe x16 slots and forced into the as x8/x4.

No effect on the throughput of the graphical interface only the M. 2 slot is located at the bottom of the Board. And by the way, except he NVMe drives, and supports SATA SSD.

However, this “full” connector – open, it does not feature the brand Ossowski radiator.

The storage media can be connected to the SATA ports, which are under consideration, the Board has six pieces. Thus, in the organization of the disk subsystem Crosshair ROG VII Hero differs markedly from the preceding fee: added a second M. 2 slot, but the number of SATA ports decreased by two.

Even a cursory acquaintance with the ASUS Crosshair ROG VII Hero (WiFi/ac) evident that it scattered atypical large number of connectors for connection of fans – as many as eight. Like Arsenal – a rarity, but also, the Board has developed control devices that are connected to these connectors, and supports adjustable speed via PWM, and the old voltage. In addition, two of the fan connectors support increased to 3 A current, and two are for pumps of liquid cooling systems and, by default, always work in full-speed mode. A pair of connectors for fans the CPU cooler uses the combined control.

In addition, ASUS did not forget to add the cost of a traditional connector for daughter card FAN Extension, which allows you to extend the array of connected fans. However, the card itself at this time, in the not supplied. To the motherboard you can connect an additional temperature sensor. Incidentally, it is quite possible to place on the abdomen of the processor: in order to be able to stretch the cable with a thermocouple inside the socket there is a hole.

In the upper right corner of the Board near the 24-pin power connector, arranged a kind of “control center”. Put back the Start button and the Reset indicator POST-code LEDs Q-LED showing the initialization process of the Board, as well as checkpoints to check key voltages with a multimeter.

Radom are connectors for led strips (addressable and conventional), as well as USB 3.1 Gen2 for connection of the respective body of the port.

The other half of the connectors and control elements on the circuit Board attributed to its lower bound. There are connectors for connection of sensors of flow and temperature liquid cooling system, additional connector for thermocouples, a couple of connectors for incorporation of led strips and connectors USB 2.0 ports and USB 3.0. There is also the ROG Extension connector, mode switches for extreme overclocking Slow Mode and LN2, and is also useful for overclocking experiments buttons Safe Boot and Retry.

All radiators available on the ROG Crosshair VII Hero (WiFi/ac), mounted on the screws and adjacent to the cooling components via elastic thermal pads.

An exception only one radiator for the M. 2 drive. He is used as a thermal interface thermally conductive double-sided adhesive tape, the manufacturer, before using need to put in “combat state”.

For the detailed circuitry underlying the Crosshair ROG VII Hero (WiFi/ac) boards have been removed all the radiators and decorative casing covering the rear face.

First and foremost interest is the power of the processor. The fact that ROG Crosshair VII Hero (WiFi ac) ASUS engineers have changed its design. Supply CPU phases became 2 more and also changed their location on the Board.

This significantly improved temperature control: the power components in the Converter power now warmed up 10-15 degrees less when compared with the cost on the basis of the X370, Crosshair ROG VI Hero.

Along with this, ASUS engineers have improved the VRM and the radiator – it’s not just two aluminum bars, connected heat pipe, and sticks with fins.

VRM in the new Board is assembled on the principle of 10+2 (VCORE + VSoC) on the basis of the PWM controller (EPU) ASP1405I which apparently is parameterone IR35201.

This means that the real phases for the CPU power five, but they are doubled when using doublers IR3599 mounted on the reverse side of the Board. Each phase uses 60-amp integrated circuit IR3555M PowlRstage and an inductor Micro-Fine Alloy.

It should be noted that this time ASUS has come up with an interesting solution – two phase power SoC split an array of ten phases of the Vcore in space into two groups – this allows you to improve the sink. Given the high power VRM to power the processor, the Board provides two 12-volt connector: standard 8-pin and additional 4 pin. Additional connector may be required in experiments on extreme overclocking.

The power supply circuit of the memory subsystem are collected in a two-phase system generated by the PWM controller ASP1103 with integrated drivers and field effect transistors ON Semiconductor.

Interesting on the ROG Crosshair VII Hero (WiFi/ac) there is external clock generator ICS 9VRS4883BKLF. Its presence means that the Board allows you to overclock the CPU not only multipliers, but also through the increase in BCLK frequency.

External clock generator is found on the flagship Socket AM4-boards quite often. But the solution is a feature of the ASUS: ROG Crosshair VII Hero (WiFi/ac) supports the new asynchronous mode in which the increased carrier frequency is applied to only the processor core and the Infinity Fabric, the memory controller and the PCIe bus remain on a standard 100 MHz.

The audio path in Crosshair ROG VII Hero (WiFi/ac) based on codec Realtek ALC1220. Also in the circuit is the DAC ESS Sabre ES9023P and amplifier Texas Instruments RC4580I. To reduce noise in analog part is separated from the other components of the non-conductive area on the circuit Board, and in addition, the manufacturer has not stinted on the special audiophile grade electrolytic capacitors Nichicon Gold series. As before, asososca sound scheme has special protection from the loud clicks of the speakers when turning on and off, and headphones that are able to “pump” the audio outputs of the Board, can have a resistance of 600 Ohms.

Wired Gigabit network is represented on a given Board, with Intel i211T, complemented by brand protection against electrical discharges LANGuard.

Wireless network Wi-Fi 802.11 ac 2 × 2 2.4/5GHz MU-MIMO is implemented as a separate module for Realtek RTL8822BE established in located in the area of the rear panel a special M. 2 slot type E.

Exactly what is provided by the simultaneous existence of Crosshair ROG VII Hero with either wireless networking support, and without Plata can be equipped with this module, and can be supplied without it.

Ports USB 3.1 Gen2, derived on the rear panel of the Board, working through an additional controller ASMedia ASM3142, which is reinforced by the switch ASMedia ASM1543 for the implementation of the port Type-C. the same Chipset USB ports 3.1 Gen2 announced at VII Hero ROG Crosshair to the inner connector, which is equipped with redriver Pericom PI3EQX, allowing you to connect it directly to the connectors of Type-C.

For the realization of the basic functions of I / o, including PS/2 ports, meets chip ITE IT8665E. Expand monitoring and fan control brand essovskie controllers ROG and TPU. But for a more accurate determination of voltages supplied to the CPU, the motherboard appeared differential operational amplifier AS324M-E1. This enhancement Crosshair ROG VII Hero can boast of a more accurate monitoring of voltages than most other boards, including authorship of the same ASUS.

To control the led backlight ASUS developers have implemented the whole scheme including the signature and AURA chip microcontroller ST Micro STM32F.

Getting acquainted with the ROG Crosshair VII Hero (WiFi/ac), we met another interesting detail: the BIOS chip on this Board has a capacity of 256 MB, while on other boards for Socket AM4 processors used twice less capacious chips ROM.

Nevertheless, the very ASUS says that now she only uses half of the available volume, and the second half is for the future, in case when the output of the promising processors, AMD wants to increase the size of the BIOS.

The processor Ryzen 5 2600: failed Favorit

Code: VZWDEAL. Enter this coupon code at checkout to get $100 discount on Samsung Galaxy Note 8. Includes free shipping. Restrictions may apply. Device payment purchase required.

One of the reasons why AMD processors at all times attracted so much attention from consumers, lies in pricing. She’s from AMD are formed in such a way that its processors seemed more bargains on the background of Intel Core, and this strategy works fine. And this year, AMD began to manage the price lever even more aggressive than before. So, if at the time of arrival on the market first Ryzen legitimate to say that compared to similar Core class they offer more cores for the same money, now this principle gradually evolved into what Ryzen can not just provide better ways of multithreading, but besides there are several cheaper processors from Intel.

This approach finds a powerful response from the fans of AMD products who appreciate the company laid the path for saving the budget. It is therefore not surprising that most of the buyers of AMD systems prefer the midrange processors, and not the flagship solutions. For example, according to major retail stores in America, Europe and Russia, the most popular AMD processor is the cheapest shestiyadernik, Ryzen 5 1600, while Intel’s sales leader of the flagship Core i7-8700K. It is significant that the difference in their price is almost twice the size, but they both have six full cores and supports Hyper-threading technology SMT or Hyper-Threading.

However, the fact that the buyers of products AMD “vote ruble” for a relatively inexpensive shestiyaderny, but not for the flagship series processors Ryzen 7, may be associated not only with the fact that in the upper price segment products of Intel in the eyes of many consumers is attractive. Plays a significant role and that the purchase of processors with eight cores for ordinary home computers has not too much practical sense. The modern game is the number of cores to provide load obviously can’t, and the professional tasks for which multicore chips are really useful, decide on a PC, only a few professionals. In other words, six cores – the Golden mean, and this is reflected in the structure of demand.

With the market launch of the second generation of processors Ryzen (Pinnacle Ridge) AMD has been enhancing its flagship OCTA-core solutions, but also prepared a couple of new processors class Ryzen 5 with just six cores. On the background of his predecessors, they have acquired quite the expected improvement due to the transition to the design of the Zen+. The new six-core Ryzen grown up the clock frequency, increased overclocking potential, and within three percent of the grown feature IPC (the number of executable per clock cycle instructions). All this is discussed in detail in our initial review Ryzen second generation, which has been extensively tested Ryzen 5 2600X.

But in light of the foregoing, among the novelties of AMD greater interest is likely not this model, and the youngest shestiyadernik, Ryzen 5 2600. His detailed tests, we have not yet made, but it is cheaper than Ryzen 5 2600X, a notable 15 percent. Thus, Ryzen 5 2600 has a good chance to become a new bestseller instead of the outdated Ryzen 5 1600 almost a year and half ago. In this review, we will try to answer the question of whether the merits of Ryzen 5 2600 overpayment of $10, which he more expensive than its ideological predecessor, and at the same time we will analyse how the new six-core Ryzen look at the background of modern processors Core i5, which is now also boast an Arsenal of six cores.

#5 2600 Ryzen in detail

So, Ryzen 5 2600 is a six-core and dwenadzatiperstnuu processor microarchitecture Zen+, largely similar to Ryzen 5 2600X. Like his older brother, Ryzen 5 2600 built on eight cores of a crystal, consisting of two units AOA (CPU Complex), each of which disabled one core. The cache memory in a shortened silicon is fully operational, which means Ryzen 5 2600 has a total of 16 MB of L3 cache.

In its positioning Ryzen 5 2600 is a step below Ryzen 5 2600X, due to lower clock speeds as at full load, and when you activate the turbo mode. AMD estimates Ryzen 5 2600 $30 cheaper than its senior shestiyadernik the second generation, and this means that it actually performs the update for Ryzen 5 1600, at higher frequencies within the same 65-watt thermal package and with all the advantages of its predecessor, including easy overclocking due to the unlocked multiplier. However, the recommended price Ryzen 5 2600 installed flush with 1600 Ryzen 5 and $10 higher.

If we talk about the boxed version Ryzen 5 2600, then there is one more thing that you need to keep in mind. This processor comes with a modest cooler Wraith Stealth, designed for removal of only 65 watts of heat.

In the operation of the processor in the nominal mode, it will be enough, but for overclocking, the cooling system will need to be replaced. So with an eye under the overclocking it is better to buy an OEM version Ryzen 5 2600 and a separate cooler, which will increase the required to build the system budget. It is noteworthy that the older and cheaper Ryzen 5 1600 in this comes with a different cooler, Wraith Spire, which has a higher efficiency and allows a moderate overclock the CPU.

As a result, the positioning Ryzen 2600 5 raises some questions. On the one hand, it is slightly cheaper Ryzen 5 2600X with a higher nominal clock frequencies, and with another – more expensive Ryzen 5 1600, CPU, which even refers to the first generation of desktop Zen, but the acceleration could come close to the flagship six-core Ryzen second generation. In such circumstances, the trump card Ryzen 2600 5 becomes moderate consumption and heat generation, which promises this processor in the nominal mode. Despite the fact that the actual operating frequency Ryzen 5 2600 are in the range from 3.6 to 3.9 GHz, AMD declares to him the estimated dissipation, reduced to 65 watts.

However, if you believe in the testimony of the on-chip monitoring SenseMI, the full power of this CPU along with a built-in SoC chip is still not within the stated frame. At full load it can reach up to 75-80 W and 65 W TDP rather describes the dissipation of processor cores apart from the built-in controllers. However, on the background of Ryzen 5 Junior 2600X CPU Ryzen 5 2600 is quite legitimate to refer to a class of energy-efficient (by the standards of AMD) solutions.

The next chart, we tried to graphically display what looks like real frequency Ryzen 5 2600 with a load of different intensity. Performing performance testing of the processor in the nominal mode in the Cinebench R15 when using different number of threads, we recorded the selected processor frequency. Its distribution depending on the CPU usage was better.

When the load on one or two core Ryzen 5 2600 can reach a maximum frequency component of 3.9 GHz. For loading in three streams, the maximum frequency is of the order of 3.85 GHz. Then, if the work is uploaded four or five nuclei, the frequency can reach 3.8 GHz, and more serious burden that makes the processor run at a frequency of about 3,65 MHz. In other words, real speed Ryzen 5 2600 are significantly higher than baseline values even at full load. However, we must mention that our experiment was conducted with the use of the productive cooler Noctua NH-U14S, and with regular Wraith Stealth indicators frequency probably would have been lower due to overheating CPU.

Thank you for unusual for AMD, the combination of a relatively high frequency and relatively low heat dissipation is a new 12-nanometer manufacturing process GlobalFoundries 12LP (Leading Performance), which compared to the previous 14-nm technology allows to achieve higher performance without significant changes in energy consumption and heat dissipation. For example, the last 65-watt shestiyadernik Ryzen 5 1600 in nominal mode developed frequency of 3.4-3.7 GHz.

The superiority in performance Ryzen Ryzen 5 2600 over the 1600 and 5 is due to another factor: Ryzen processors of the second generation had technology Precision Boost 2 (PB2) and XFR2 with advanced functionality. PB2 learn how to effectively raise the frequency of the processor during multi-threaded load, not loads of work all the available cores, and XFR2 in addition to this can be very flexible adjustment of the operating frequency of the processor under the capacity of the existing cooling system. As a result, the real advantage Ryzen Ryzen 5 5 2600 over 1600 in nominal mode can reach up to 13 percent.

To illustrate the performance Ryzen 5 2600 correlated with the performance of six-core Ryzen first generation at different loads, we have constructed the following chart that shows the relative performance of AMD processors in the test Cinebench R15 rendering when using different numbers of compute threads. Indicators Ryzen 5 2600 taken as 100 %, the other results of the test are normalized relative to these values.

It is curious that in the Cinebench R15 CPU Ryzen 5 2600 is not only faster Ryzen 5 1600, but almost always ahead of Ryzen 5 1600X, at least in multi-threaded load. From the point of view of formal specifications senior shestiyadernik last generation promises higher operating frequencies, but new technology PB2 and XFR2 are so aggressive that in practice the picture is different.

Ryzen 5 2600, like all other processors Ryzen second generation compatible with Socket AM4 motherboards based on chipsets three hundredth and four hundredth series. To use Ryzen 5 2600 circuit Board on the newer chipsets X470 and B450 does not necessarily. Old Socket AM4 platform work perfectly with the new Ryzen after updating the BIOS and do not impose any penalty in terms of performance. Technology PB2 and XFR2 remain functional and, therefore, with a relatively cheap Ryzen 5 2600 may be advisable to use a motherboard on the basis of the B350, which today dropped in price to $60-70. And if you plan on overclocking, then the main thing to look for when choosing the platform is on the quality of the power supply circuit of the processor, not the chipset.


It is believed that processors Ryzen second generation, the production of which used the new 12-nm process technology, have better overclocking potential. However, in practice, the difference from its predecessors is not too strong: limit the dispersal of various Ryzen two thousandth series only a little beyond 4-GHz the border.

Ryzen 2600 5 confirms this rule: with air cooler Noctua NH-U14S, we were able to increase frequency without compromising the stability only up to 4.0 GHz. It turns out that Ryzen 5 2600 for overclocking capabilities are almost the same Ryzen 5 1600, the dispersal of which, in similar circumstances, stayed in the range of 3.8-4.0 GHz.

At the same Ryzen 5 2600 overclocking was worse than their more expensive counterparts: other model Pinnacle Ridge that have passed through our hands, took the frequency to 4.1 GHz with a relatively small increase in voltage. But in order for your instance of Ryzen 5 2600, working at a frequency of 4.0 GHz, could be tested in LinX AMD Edition 0.8.0, the CPU voltage had to be raised to 1,425 In simultaneously enable Load-Line Calibration. And this, frankly, long-term use can cause irreversible degradation of the silicon is completely safe for crystal Pinnacle Ridge is considered not only the voltage above 1.35 V.

You need to pay attention to the fact that the processor power consumption in this mode increases up to 150 watts. Obviously, here we need a very efficient cooler, and no a-box solutions will not work. Even with high-performance Noctua NH-U14S worth a third of the price of cooled CPU temperature reaches 82 degrees. With more than simple coolers, obviously, the dispersal of such Ryzen 5 2600 as our instance, up to 4 GHz, it would be impossible in principle.

From all this we can conclude that for the manufacture of Junior modifications Ryzen second-generation AMD uses less good crystals. And this is another argument in favor of models with the end of the X title. As practice shows, they are accelerated somewhat better.

Simultaneously with the announcement of the new AMD CPU microarchitecture Zen+, which received the code name of Pinnacle Ridge, the company introduced a chipset X470. Interestingly, if in technical terms, this chipset is no different from the X370, the payments based on it, as conceived by AMD and its partners, needs to become more sophisticated and reliable. And here we are talking not so much about the support of high-speed RAM and the optimizations work with it when overclocking, but about adapting and strengthening the power circuits of the processor to support more CPU Ryzen 7 2700X with the level TDP of 105 watts. In addition, X470 should have lower heat and power consumption than the X370. In other words, existing chipset is lightly polished, giving the motherboard manufacturers a good reason to release another series of their products.

And they were not long in coming. One of the first was noted by company MSI, released on the X470 five new motherboard. The flagship of the fresh series has become a model X470 M7 MSI GAMING AC, which we now examine and test with the new processor Ryzen 7 2700X.

If you compare the characteristics of the new M7 MSI X470 GAMING AC and its predecessor M7 MSI X370 GAMING ACK, the first, in addition to supporting the new processors (which will run on old motherboard) and faster memory differs from the second absence is no longer relevant port U. 2 and a slightly greater number of USB-ports (17 vs 16). All. But this is only from the point of view of technical characteristics. In fact, changes in the novelty a lot more. However, everything in order.

#Packaging equipment

The cardboard box comes X470 M7 MSI GAMING AC is probably one of the brightest on the market. Against the background of a murderous star of space floats the image boards, bordered with various logos and stickers. In this registration package is simply obliged to draw attention to themselves, standing out against any competitors.


On the reverse side of the box marked the key features of this Board, given its brief description, lists the connectors on the rear panel and a short warranty.

Standard sticker on the end of the box contains information about the model and the product serial number, barcodes and a brief listing of the interfaces.

Inside the box is divided into two compartments. At the top on a separate tray located motherboard, sealed in antistatic bag. The area under it is possible to find components, divided into two parts.

The first four SATA cables with latches, blanking plug on the rear panel, a rigid connecting bridge for SLI, the cables to connect the lights and the antenna for the wireless module.

The second part of the information-chip: brief and full instructions manual for the Board, the memo on the installation of the CPU into the socket, CD with drivers and utilities brochure, and stickers for your SATA cables.

X470 M7 MSI GAMING AC is produced in China, and provides a three year warranty. The fee is not cheap, as in the Russian stores, this model you can buy at a price of 17 700 rubles, and the closest to us foreign online trading sites its price starts with a mark of 208 euros.

#Design and features

X470 M7 MSI GAMING AC – motherboard layout classical form factor ATX. Its size is equal to 304 × 244 mm. Looks new nice and easy, but this is not to say that it is boring.

Neskuchnoe is achieved thanks to the shaped plastic casing exits and stylish radiator on the chipset, combined with the radiators on the ports drives 2.

On the interface panel has eight USB ports, two of which are version 2.0, four – 3.1 Gen1 and two – speed Gen2 3.1 types A and C. Also here you can find a reset button the CMOS and updating the BIOS, combo PS/2 port, connectors for antennas, wireless communication and LAN-socket RJ-45, optical output, and five 3.5 mm audio jacks with gold plated contacts inside.

All add-on components attached to the PCB with screws, so they are convenient and easy to remove. In “pure” form fee as follows.

The location of all elements on the PCB we borrowed from the instruction manual and reproduced it below.

Compared to how it looked processor Socket Socket AM4 on the boards of the previous generation on the chipset AMD X370, here he has not changed.

Starting with the first BIOS version, the Board supports the old processors with the core of the Summit Ridge, and the new, with Pinnacle Ridge and Raven Ridge. Not forgotten, and budget processors A-Series with the core Bristol Ridge.

The system processor power is built according to the “12+2”, where 12 phases are reserved for the power cores and another two on the memory controller and other auxiliary voltage. On the reverse side of the PCB soldered doublers International Rectifier IR3598.

For the power management of the processor on the Board is responsible for the PWM controller from International Rectifier IR35201.

Standard connectors to connect power (24 and 8 pin) added one 8-pin, also oriented with latches on the outside.


Note that the Board runs stably even in the case if the third connector is not connected to the power supply.

The AMD X470 released in Taiwan on the 3rd week of 2018 and applies to version B2. It is closed with a metal heat spreader, so do not fear accidental chips and scratches.

The possibility of a new set of system logic AMD is shown in the diagram below.

All slots of memory modules on MSI GAMING AC X470 M7 got a brand new metallic sheath of Steel Armor and extra soldering points. Above them are marked, also marked with a priority couple for modules.

Branded DDR4 Boost technology, which consists in the optimal distribution of traces in different layers of the PCB, provides a cleaner signal, which in turn will allow to reach higher memory frequencies during overclocking. The new AMD X470 (and, accordingly, the MSI X470 GAMING AC M7) supports DDR4 memory up to a frequency of 3600 MHz. This is probably the only serious advantage of the new chipset AMD before the old X370. Today the list of officially supported card modules is huge and continues systematically to grow.

For power management of the memory meets a single-channel PWM controller.

Let’s add that the maximum amount of memory can reach 64 GB and supported preset frequencies/timings A-XMP.

X470 M7 MSI GAMING AC is equipped with three physical PCI Express 3.0 x16, of which the first two have a metallic shell of Steel Armor. However, only the first slot can run in full x16 mode, but when installing two graphics cards CPU lines between them will be divided according to the scheme x8/x8.

Accordingly, it supports the technology NVIDIA 2-way SLI and AMD 2-way CrossFireX. The third PCI Express 3.0 x16 can only run in x4 mode, and the remaining three “short stack” — chipset PCI Express 3.0 x1, which are designed for expansion cards.

For switching of modes of the slots on the Board are responsible multiplexers ASM1480 production ASMedia, soldered on the reverse side of the PCB.

Six SATA ports 3 with a bandwidth up to 6 GB/s is implemented solely by the chipset AMD X470 (actually, anything additional is not necessary) and is oriented horizontally.

We will add that from connected drives connected to SATA 3, the fee allows you to collect arrays of levels RAID 0, 1 and 10.

The MSI X470 M7 GAMING AC has two port Turbo M. 2 with twin FROZR cooler Shield.

Both ports support both SATA and PCI-E NVMe drives types 2242/2260/2280, but summed up to the bottom of the line PCI-Express 2.0, while the upper is 3.0. In addition, you need to remember that when installing the drive in the lower M. 2 will be disabled third SATA port.

Fitted with 17 USB ports, of which eight are located on the front panel, and nine can be connected to the connectors on the PCB.


Two fast USB 3.1 Gen2 throughput to 10 GB/s displayed on the rear panel (Type-C and Type-A) and implemented by the chipset AMD X470, and another of the same speed the port is implemented by controller ASMedia ASM1143 and is designed to display on the front panel of the system unit. Supported by proprietary technology MSI X-Boost, MSI Super Charger and Double ESD Protection.

Wired LAN on the MSI X470 M7 GAMING AC provides Gigabit LAN Killer E2500, the technology supports traffic prioritization and lower latency Advanced Stream Detect 2.0 and the technology of electric protection against voltage surges and static electricity, Protect the LAN.

In addition, it is supported by intelligent control of network traffic through the app the MSI GAMING LAN Manager. The company network “killer” is the wireless network adapter Intel Dual Band Wireless-AC 8265 supporting Wi-Fi 802.11 a/b/g/n/ac simultaneous dual band 2.4 and 5.0 GHz with a bandwidth of up to 867 Mbps, it also provides the Bluetooth 4.2.

Sound system on the Board migrated to its predecessor, it is well known to our readers the complex MSI Audio Boost 4, which is based on 7.1-CH HD audio codec Realtek ALC1220, protected from electromagnetic interference by aluminum casing.

To improve the sound have an abundance of audiophile capacitors Chemi-Con, separate layers of the PCB for the left and right audio channels, as well as isolated from the rest PCB sound area.

Complement this set of hardware protection from clicks, gold contacts connectors and advanced surround Sound 3 speed and performance.

For monitoring, Super I/O and fan control for MSI X470 GAMING meets M7 AC controller Nuvoton NCT6795D-M.

Board can simultaneously control up to six fans with support for pulse-width modulation (PWM). One connector supports a current of up to 2A — it is designed to provide power to the pumps of the cooling system or other energy-intensive consumers.

Lighting system for GAMING MSI X470 M7 AC implemented a range of LEDs with the opposite sides of the zone of RAM, and a casing back panel.

Controls lighting modes microcontroller with marking 104GFA from an unknown manufacturer.

Through the app MSI Mystic Light, there are a number of modes of the backlight and infinite colors — 16.8 million colors.

Of course, the handset supports external connection of led strips that can be synchronized with the main lighting Board.

In addition to four MSI EZ Debug LEDs on the Board is a convenient indicator of POST codes located in the lower right corner. Underneath you can see a round switch that lets you choose from 11 levels of automatic overclocking.

There – on the bottom edge of the PCB – soldered internal connectors USB and audio connectors for the cables the chassis front panel, power button and reset. In General, it is difficult to say what connectors X470 M7 MSI GAMING AC is not enough, there is.

The cooling elements of the power supply circuits of the processor implemented with two ribbed radiator with pads.

By the way, the Board has two sensors for each of the CPU power circuit and their temperature, we must pay attention during the tests.

A review of the Core i7-8086K: the holiday comes to us?

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

If you follow the news of the processor market, you probably know that on June 8, in honor of the 40th anniversary since the release of the Intel 8086, the first in the history of the chip with x86 – Intel has released a special limited edition “jubilee” Intel Core i7-8086K. This festive new – improved modification of the flagship six-core Coffee Lake for the platform LGA 1151 v2 capable “out of the box” to develop the frequency to 5.0 GHz. This value is not just a beautiful figure, she has for the Intel symbolic value. It is taken to say that over the past four decades the frequency of processors has grown at exactly 1000 times.

Along with this microprocessor giant boasts of other achievements, albeit not having as beautiful of a numerical expression. For example, the fact that the number of transistors in the first x86 processor was 29 thousand, and now (Coffee Lake) it exceeds three billion. The resolution of the fabrication process has decreased from 3 µm, was used in 1978 to 14 nm. And also the fact that the density of transistors in the processor chip during the forty-year evolution from 8086 to Coffee Lake has increased more than 22 thousand times.

But the greatest impression in the characteristics of the anniversary processor produces still, not the number of transistors and die area, and high frequency is 5 GHz, which until now no serial Intel x86 processors did not take (in parentheses recall the existence of AMD FX-9590, which managed to touch the coveted around 5 GHz in 2013). Some enthusiasts were taken on a level six-core Core i7-8700K through overclocking, but now, in honor of the holiday, Intel seems to have decided to release a pre “overclocked” CPU for those not interested in overclocking at least, so it is possible to interpret the announcement of the Core i7-8086K. And it looks quite in the spirit of the company: from our memory not yet erased the previous anniversary CPU, the Pentium G3258that Intel released for the 20th anniversary of the brand Pentium. It had an unlocked multiplier, which gave a purely budgetary and ordinary CPU considerable additional practical value.

However, looking ahead, will immediately disappoint: this time to make as generous gift from Intel did not work, and a marked superiority in consumer qualities over other Coffee Lake and Core i7-8086K no need to wait. Despite the fact that the novelty is confined to an even more memorable date in the history of the company and is produced with much more pomp, in reality it is a very close synonym Core i7-8700K.

In fact, the unwillingness to grant Intel Core i7-8086K to tests in independent publications, apparently due to the fact that the CPU is actually not exactly what it is trying to give the marketing Department of the manufacturer. In this survey, for which the sample Core i7-8086K we had to buy in the store, we will try to explain why it released a limited batch of 50 thousand units Core i7-8086K is likely to be perceived as a collector’s item, by and large have no significant practical advantages compared to the already present on the market six-core flagship Coffee Lake.

#What is wrong with the Core i7-8086K

If you look at the official specifications of the Core i7-8086K that Intel publishes on their website, there is a strong feeling that we are dealing with a pre-overclocked at the production stage Core i7-8700K.

Core i7-8086K Core i7-8700K
Code name Coffee Lake Coffee Lake
Production technology, nm 14++ 14++
Cores/threads 6/12 6/12
Base frequency, GHz 4,0 3.7 V
The Turbo Boost 2.0 Frequency, GHz 5,0 4,7
L3 cache MB 12 12
Memory support DDR4-2666 DDR4-2666
Integrated graphics GT2: 24 EU GT2: 24 EU
Max. the graphics core frequency, GHz 1,2 1,2
PCI Express 16 16
TDP, watts 95 95
Socket LGA 1151 v2 LGA 1151 v2
The official price $425 $359

Here the Core i7-8086K really looks like an improved version of the Core i7-8700K increased to 300 MHz frequency that is converted to base frequency at 4.0 GHz and the possibility of automatic overclocking in turbo mode up to 5.0 GHz. And, importantly, these changes do without growth the calculated heat dissipation, which remained at the usual 95-watt mark. Because Intel not announce any changes in technological process, we can conclude that Core i7-8086K selected the most successful semiconductor crystals, characterized by less heat dissipation and a better frequency potential.

But if looking into a table with characteristics, you decide, though Core i7-8086K – processor, which is due to the higher frequency is superior to the Core i7-8700K productivity by 6-8 per cent, we have to disappoint you. In fact, such the advantages it gives: setting turbo mode Core i7-8086K such that it can reach higher frequencies only during single-threaded load, and when loading two or more cores, the maximum achievable frequency Core i7-8700K and Core i7-8086K identical.

  Nominal frequency, GHz Max Turbo Boost 2.0 frequency, GHz
1 core 2 cores 3 core 4 cores 5 cores 6 cores
Core i7-8700K 3.7 V 4,7 4,6 4,5 4,4 4,4 4,3
Core i7-8086K 4,0 5,0 4,6 4,5 4,4 4,4 4,3

Thus, in most situations, the Turbo Boost technology can overclock the Core i7-8086K and Core i7-8700K to the same limits. The difference exists only when the load on one core, in which case the anniversary processor is really able to take a higher frequency. But in reality it means little: refined single-threaded load now occurs very rarely at least because even if the executable of the foreground application is single-threaded, almost always parallel to working with him and some background processes, including relating to the operating system. In other words, if we talk about the functioning of the processors in the normal mode in real life, the major reasons why Core i7-8086K must somehow differ markedly in performance from its conventional counterpart, is not visible.

A separate explanation should be done relative to the nominal frequency, which for the Core i7-8086K also stated at a higher value. Formally, this means that at full multithreaded load, the heat dissipation Core i7-8086K will not go beyond the established framework of the thermal packet 95-watt boundary at a frequency of 4.0 GHz. While for Core i7-8700K compliance with TDP of 95 W was only guaranteed to 3.7 GHz, which is a clear proof of the top quality of semiconductor crystals used in the composition of the jubilee processors.

But again, to real performance, it all has a very distant relationship. To keep our own energy, and thermal parameters in the boundaries specified TDP, the processors try only when you disable Multi-Core Enhancements (MCE). However, modern motherboards on the basis of the older chipset Intel Z370 activated by default, and control over the actual dissipation is not conducted. Therefore, elevated nominal frequency Core i7-8086K will be converted only slightly lower for practical power consumption and heat generation of the processor, but not the differences in operating modes.

Illustrate the situation with the performance by using the following chart, which displays the relative performance of the Intel Core i7-8700K and Core i7-8086K in the test Cinebench R15 rendering when using different numbers of compute threads. Indicators Core i7-8700K taken as 100 %.

As you can see, the difference in performance of conventional processor and limited editions is indeed observed only in a single-threaded load. Here inevitably arises the question concerning the justification of the prices of the Core i7-8086K. The fact that Intel has made it almost a 20% margin, which in the observed situation, performance does not look fair.

However, the price of the jubilee of the processor is likely to have been determined not on the basis of consumer characteristics as reasons of status product. Still, the Core i7-8086K is more of a souvenir released by the limited circulation in 50 thousand copies, than the conventional serial processor. It is absolutely not intended to become a replacement or further development for Core i7-8700K, and the difference in price at $ 66 – a kind of “collection of collectors”.

Because they made overpayments to customers, Core i7-8086K in addition to the jubilee of the CPU box will get a special design with the words “Limited Edition”; the certificate confirming the possession of a unique anniversary processor; and a welcome note from the CEO of Intel, Brian Krzanich, just recently became a former.


Despite the fact that the situation in the nominal mode Core i7-8086K looks like some kind of double cross, the pros of this processor might appear during acceleration. Of course, do not think that the jubilee six-core Coffee Lake just have to accelerate above typical Core i7-8700K for 4.7-4.9 GHz. But Core i7-8086K could be more pliable under normal non-extreme overclocking. At least, use for Core i7-8086K specially selected semiconductor crystals with reduced thermal performance can become the reason for at least a small shift of the critical heat CPU overclocked to more distant frontiers.

In other words, it would be logical if, for example, the 5.0 GHz could take all instances of a Core i7-8086K the polls. Each of the cores of this processor separately should work at this frequency, based on the specs of the turbo mode, so it is logical that the 5-gigahertz frequency will be available to the processor as a whole. However, in some cases, may require scalping, because even in honor of the 40th anniversary of the x86 architecture, Intel did not return under the cover of CPU high performance thermal interface. In Core i7-8086K again used the traditional polymer compound that with the growth of dissipation becomes a bottleneck in the way of heat dissipation from the CPU crystal, and therefore raises serious criticism from the enthusiasts.

But we for the initial experiments on overclocking Core i7-8086K to the scalp to resort did not. Was wondering what this CPU will be able in its original form.

In order to obtain a comprehensive picture of the properties of overclocking Core i7-8086K, was built by a “temperature map” that describes the heating of an existing instance of the processor at various frequencies and voltages. To generate load we used the utility LinX 0.9.2, which is based on library Intel Math Kernel Library and is actively working with vector instructions AVX/AVX2, thereby provoking maximum possible heating of the processor. The cooling of the processor was performed using a productive air cooler Noctua NH-U14S.

However, most of the Core i7-8086K compared to we previously encountered instances of the Core i7-8700K able to work at lower supply voltages. The frequency of 4.0 GHz, it is quite achievable already at a voltage of 1.0 V, and in this mode, no stability issues are observed. But even in such a gentle state, the processor is still noticeably heated: obtained in this case 65 degrees immediately suggests that the outstanding overclocking will not be due to overheating CPU.

So it is: the maximum frequency at which Core i7-8086K was able to be tested for stability in LinX 0.9.2, steel only 4.8 GHz, obtained at a voltage of 1,225 V.

It would seem that the CPU voltage is not so high, but core temperature still very close to the 100-degree limit on which desktop Coffee Lake turns on the throttle. It turns out that there is nothing “beautiful” 5.0 GHz under any load it can not go. In its original condition Core i7-8086K at the overclocking potential was similar to the ordinary Core i7-8700K, which if possible overclocking up to 5.0 GHz, then the vast majority of cases, only with the addition of a corrective coefficient of -2 under AVX loads.

Whether in such a situation to help the scalp? Most likely Yes, because the acceleration, obviously, rested not in the limit of silicon and temperature. So we decided to replace Intel’s termoenergetyczny material under the CPU cover on Coollaboratory Liquid Ultra – liquid metal with a clearly better thermal conductivity.

Procedure itself scalping hardly deserves detailed description. Everything is done exactly as in the case of Core i7-8700K – anniversary Core i7-8086K perfect does not differ from it in physical performance, including how heat-dissipating cover is mounted on the CPU Board and that she’s underneath it.

The performance of the procedure is also not in doubt: the CPU temperature achieved in LinX 0.9.2 in overclocking modes, immediately dropped by about 15-20 degrees, which seemingly cleared the way for the conquest of the coveted 5-gigahertz mark. However, there was another problem. Close to linear increase in frequency during acceleration at the existing instance of Core i7-8086K was observed only up to 4.8-4.9 GHz. Further, to ensure the stability required for more serious increment of tension, which immediately resulted in a noticeable temperature rise. As a result, the change termoenergetska material and could not cause a qualitative improvement in the overclocking potential. Temperature map of the Core i7-8086K has improved, but the spectacular view is still not acquired.

In the end, the maximum acceleration scalped Core i7-8086K was only possible to 5.0 GHz – values, albeit symbolically important, but imagination is not striking. To the same 5 GHz (including when working with AVX/AVX2 instructions) are able to accelerate after conventional scalping and Core i7-8700K.

The only noticeable difference the Core i7-8086K found during acceleration, only concerns the fact that the processor is able to conquer a fairly high frequency with a more restrained increase in voltage. However, full stability at 5.0 GHz, we managed to achieve only at 1.35 V. this means that the maximum frequency limit of semiconductor crystal under consideration of the product has remained close to what could boast six-core Coffee Lake before. It turns out that if to have in mind the operation in the overclocking modes, the anniversary processor should not be considered guaranteed best alternative to conventional flagship Coffee Lake. Core i7-8700K and Core i7-8086K approximately equal in this respect.

All this means only one thing: the selection of crystals for the anniversary of processors is not frequency potential, and for some other indications, for example, on energy at the frequency of 4.0 GHz or ability to work at this frequency with a relatively low voltage. Yes, it can be converted into better overclocking potential, but there is no determinism in this. As shown by experiments with our instance of Core i7-8086K, on the one hand, the processor may have a low VID and look promising in the nominal modes, but high frequencies to take very reluctantly.

The obtained results overclocking testing need another comments. A couple of weeks ago Silicon Lottery, online service, which deals with the selection and scalping processors, has published his statistics of overclocking Core i7 – 8086K, according to which about 60 percent of the instances of the Core i7-8086K able to take the frequency of 5.2 GHz.

Does this mean that tested in our laboratory processor is a very bad representative of a new family? Not at all. It’s in the methodology used Silicon Lottery. There are two basic things: they disperse the processor a reduction factor -2 under AVX loads, and for cooling is used one of the productive closed cooling system. And if this approach to apply to our CPU, then it will be quite typical and will be included in the 60 per cent of the most successful instances. In particular, additional testing showed that ITS a NZXT Kraken X72 he passes stability tests that don’t use AVX instructions, at the frequency of 5.2 GHz.

Only need to increase voltage to 1.4 V, but ITS with the withdrawal of the heat generated by the CPU copes. No problems with the stress and pass the test AVX-stability at 5.0 GHz.
