Tom’s Hardware Verdict
Asus did a great job designing a sharp-looking Radeon RX Vega 64 card that performs better than AMD’s reference implementation. We would have liked to see the company put a thermal pad between its PCB and backplate, though, to counter high board temperatures under load, along with using slightly higher fan speeds. Regardless, the prices of all Radeon RX Vega 64 models remain a little too high for a recommendation at this time.

Features & Specifications
AMD’s Radeon RX Vega 64 is as fast or faster than a GeForce GTX 1080 in our gaming benchmarks. That much is well-established fact. But up until recently, the flagship Vega card was priced well beyond Nvidia’s alternative, making it easy for us to recommend the GeForce instead. Now that Vega 64 is becoming more affordable, though, it’s getting harder to choose between the two high-end options.
The Asus ROG Strix Radeon RX Vega 64 8GB OC Edition we’re reviewing today does cost $70 more than the least expensive Vega 64 model (and $100 more than the cheapest GTX 1080). However, it does add RGB lighting, a big heat sink, quiet fans, a second HDMI port for VR headsets, and high-quality components. In the end, those extras aren’t enough to justify such a big mark-up, particularly when the Radeon desperately needs a price break to secure a competitive advantage.

Unboxing, Look, & Feel
Weighing in at 1286 grams, this card lands between Gigabyte’s much lighter Radeon RX Vega 64 Gaming OC 8G and the aforementioned behemoth from Sapphire. Asus goes big on the physical dimensions, too. Its ROG Strix Radeon RX Vega 64 8GB OC Edition measures 30.2cm long, 12.7cm tall, and 4.5cm deep.

Three 90mm fans are mounted in 92mm openings. With their special shape, a total of 11 rotor blades per fan provide airflow and turbulence, rather than just static pressure. This should prove beneficial to Asus’ thermal performance.
The backplate is embossed with an illuminated ROG logo. That plate doesn’t help with cooling at all; it’s primarily meant to look good and give the card some rigidity.
Plan for an extra 5mm of clearance (at least) behind the ROG Strix Radeon RX Vega 64 8GB OC Edition. This may cause problems on some motherboards, particularly if the heat sink/backplate intrude on an occupied expansion slot or large CPU cooler.
As we can see from the bottom, Asus employs vertically-oriented fins. At the expense of occupying a third slot with its 2. 5-slot design, the company does open up more room for airflow.
The dark plastic shroud covers part of the top, creating room for a back-lit ROG logo. Toward the back, you’ll find a pair of eight-pin power connectors that are rotated by 180 degrees and recessed a bit, sitting flush with the PCB.
In addition to five 6mm heat pipes, the board’s closed end reveals two PWM-controlled fan connectors able to accommodate optional case fans, an RGB output, and LED headers.
The rear bracket plays host to five display outputs. A pair of HDMI 2.0 interfaces is ideal for anyone with a VR HMD, while two DisplayPort 1.4 connectors make multi-monitor configurations easy. Dual-link DVI ports aren’t as pervasive as they once were, but Asus still gives you one. Since the card’s cooling fins face up and down, we’re not particularly worried about those five outputs interfering with airflow.
Although Asus’ official documentation claims a 1590 MHz boost clock, GPU-Z reports 1630 MHz. That specification is mostly wishful thinking though, given a 295W power limit.

Inside the box
Along with the GFX card box also includes Software installation CD, quick start guide one PCI-e power cable and two ROG Velcro cable tie straps.
Card is having great looks with complete black theme. In front we have a big triple fan cooling with patented wing-blade fans mounted on to the new maxcontact technology heatsink.
Back of the card have a thick back-plate with complete coverage of the PCB. Beside etched graphics backplate also have a large â€˜Republic of Gamers’ logo with RGB lighting which can be fully customized.
Due to the thick cooling solution card is a 2.5 slot design, but you will need 3 standard slots available to accommodate the card inside your PC.
This Strix card features 2 X 8-pin PCI-E power connectors, which along with the PCI-E lane’s power provides this card with an over 395w of power.
At the rear of the card we have lot of connectivity options consisting of 2 X DisplayPort 1.4 connections, 2 X HDMI 2.0 ports and a DVI-D connector.
On the case inside end of the card we can see the new Asus Fanconnect II headers â€“ a unique feature allowing you to connect two 4-pin CPU / GPU PWM-controlled fans instead of plugging them into your motherboard.
Removing the heatsink reveals all nickel plated cooling solution with six copper pipe fused onto a big copper base which is finely milled to give the GPU silicon perfect flat contact with the heatsink. Whole PCB is given rigidity with strong aluminum frame.
As you may notice this PCB don’t look like a regular graphics card PCB, with a big GPU chip surrounded by lot of memory module chips. This is indeed a first glimpse of how our graphics cards will look in near future. AMD with its Vega GPU lineup has introduced a new way of reducing memory latency by installing two high speed HBM2 memory silicon alongside Vega 10 GPU core onto a single GPU package.
Below you can see two HBM2 memory silicon alongside Vega 10 GPU core. This is a retail card not a review sample, so you can clearly see that whole GPU package is having a uniform contact area with cooler. Whereas on some sites with review sample reported of the lower sitting HBM2 stacks than the main GPU core.
Rest of PCB looks empty, holding only power delivery and output circuitry. Main power section is having a 11 Phase designed power section using International Rectifier’s IR 3555M a integrated PowIRstageÂ® contains a synchronous buck gate driver IC which is co-packed with control and synchronous MOSFETs and a Schottky diode to further improve efficiency and each phase has output current capability of 60A. Power controller used in the custom design is an International Rectifier IR35217 chip.

Overview of ASUS ROG Strix Radeon RX Vega 64 OC
Video cards Radeon RX Vega were quite long-awaited for fans of the «red» camp. Many hoped for a more pleasant price tag than that of a competitor, someone expected the highest level of performance, miners in anticipation of the RX Vega 64 saw it as a “gold mine”. However, RX Vega 64 can already be found on store shelves but only in a reference version, and while other manufacturers are dozing, ASUS introduced a non-reference version of the ASUS ROG Stris RX Vega 64 OC Edition. As the tests of my colleagues show, the reference RX Vega 64 turned out to be quite hot and noisy, so it is doubly interesting to look at the first non-reference design.

Packing and contents
ASUS ROG Stris RX Vega 64 OC is packed in a fairly large box, the dimensions of which seem to hint at the impressive size of the video card itself. In addition to large dimensions, the box received a very colorful and informative design. The video card itself is depicted on its front side, as well as a fairly large emphasis is placed on the red design, which immediately makes it clear that we are talking about an AMD family video accelerator, and a huge V sign will make it clear and irrevocably that this is the long-awaited RX Vega. In the back parts of the package describe the main technical characteristics and main marketing features of the video card. The delivery set is not rich:
- installation and configuration instructions;
- driver disc;
- adapter from two 6-pin to one 8-pin connector;
- two cable ties.
Appearance, circuit board, cooling system
Externally, ASUS ROG Stris RX Vega 64 OC has the traditional design for the ROG Strix series: the same strict design with chopped shapes, which can play with different colors thanks to ASUS Aura backlight. The casing of the video card is quite massive and made of plastic. A metal backplate is installed on the back of the card, on which the Republic of Gamers logo is clearly visible. A backplate is always good, because it protects the video card both from mechanical damage and prevents the PCB from bending, because the entire cooling system weighs quite a lot. only digital and it will no longer be possible to connect an old VGA monitor through an adapter. It’s also nice that the card has two HDMIs and is convenient for connecting VR headsets. On the back side there is a connector for connecting an LED strip so that it glows in unison with the video card, and there are also two connectors for connecting case fans, respectively, their rotation speed will depend on the temperature of the video card, and not on the temperature of the processor. The side view of the video card makes it possible to externally assess the useful area of the radiator of the cooling system, but in general, the video card occupies 2.5 expansion slots due to the massive cooling system, which is simply necessary for RX Vega 64. Active elements cooling systems are three at once 90 mm fans with an optimized shape of the impeller that creates optimal airflow and IPX5 dust protection. a coating that does not impair heat dissipation, but at the same time protects the tubes from oxidation (darkening), as is the case with ordinary copper tubes. Contact with the graphics chip is not direct, but it passes through an almost perfectly polished and smooth area, it is also worth mentioning that the RX Vega 64 crystal carries both the graphics chip and the HBM2 memory on the same substrate, so the memory is also cooled from this area. Considering the power-hungry nature of the Radeon RX Vega 64 chip compared to the ASUS ROG Strix GeForce GTX 1080 Ti OC, the VRM zone cooling system has been redesigned for the better. Now the heat from the power phases is taken through the thermal pad directly to the radiator. A small radiator is also installed on the reinforcing metal plate to cool the two power phases of the memory modules. The reference uses two 8-pin power connectors at once, which, together with the PCI-e slot, can provide up to 375 watts. The power system is called Super Alloy Power II and is recruited exclusively from high-quality components.
ASUS ROG Stris RX Vega 64 OC is equipped with bright backlight near the fans, which is great if you have a case that allows you to install a video card parallel to the motherboard, and if not, then you don’t have to be upset, the Republic of Gamers logo is highlighted on the side side and on the backplate. An example of the backlight is shown below. The backlight is configured in the ASUS Aura application of the same name. It is possible to work in the modes: constant glow, breathing, flash, cyclic switching of colors, pulsations to music, color changes depending on temperature.
Of course, the most spectacular mode is the color cycling, and don’t forget that the ASUS Aura backlight can be synchronized between ASUS devices and other ASUS Aura-certified devices. At the moment, the ASUS Aura backlight system is one of the most customizable and supported by manufacturers.

AMD Radeon driver version 17. 10.1. The video card was used in factory OC mode.
All tests in games were carried out at maximum graphics settings in 4K without anti-aliasing. The Intel Core i7-7740X processor was overclocked to 4.9 GHz, just in case.
FPS capture was done by Fraps application within 2 minutes of the game without using built-in benchmarks, a real gameplay test, everything we like.
At the time of testing the RX Vega 64, there were no powerful video cards in the editorial office for comparison, so this is a test without loud conclusions, but in general we can say that the miracle did not happen and the top RX Vega lags behind the GTX 1080 Ti and struggles with the GTX 1080 for a place in the sun, losing or, conversely, winning from project to project. Tests in 4K show that, unfortunately, it will not work to achieve the coveted 60 FPS at maximum graphics settings and you will have to be content with either lowered settings or be confident in the game without lags in 2K resolution.
Overclocking and operating temperatures
The average temperature of the graphics chip in idle is 48°C, and the video card is not audible at all, because its fans start to turn on as soon as the chip temperature exceeds 55°C. ASUS ROG Stris RX Vega 64 OC is calibrated to be as quiet as possible even with decent factory overclocking to 1630 MHz core and 945 MHz memory. But even with such a factory boost, the temperature in The Witcher 3 at 4K and at extreme quality did not rise above 77 ° C, at that time the temperature in the room was 26-28 ° C, and the fan speed rose to 1200 rpm. Despite three fans at once and fairly high maximum speeds, ASUS ROG Stris RX Vega 64 OC remains almost silent. The ideal speed at which the video card is not audible in a closed case is 1200-1300 rpm, and at maximum speed, let’s say, they asked for it themselves, the noise reaches 49dB with the background noise of the room 28 dB, but not a single benchmark can warm up the card so that it spins the fans so that the cooling system still has a good margin. It is worth noting here that the video card driver sometimes gave completely incorrect data to GPU-Z. The overclocking potential of the video card is great, without much difficulty, ASUS ROG Stris RX Vega 64 OC reached a frequency of 1700 MHz for the core and 1100 MHz for memory. But to work at such frequencies, you need to take care of lowering the operating temperature and set the fan speed forcibly to 90% of the maximum speed, and in this mode, the acoustic noise is no less than that of the reference, so there is not much sense in such overclocking, all the advantage of a non-reference design is lost. However, ASUS ROG Stris RX Vega 64 OC is optimally overclocked from the factory.
As an additional software, ASUS offers its own GPU Tweak II utility — this program is convenient for monitoring and fine-tuning the video card, as well as creating your own work profiles. To control the backlight modes, the manufacturer has provided ASUS Aura software.
Impressions and conclusions
Speaking specifically about the ASUS ROG Stris RX Vega 64 OC, this is an excellent non-reference solution that got rid of the “childish” diseases of the reference version of the RX Vega 64. Vega performed by ASUS turned out to be both noticeably quieter and colder than the reference factory design, there are no complaints specifically against ASUS in this regard.
There are questions only to the Radeon RX Vega itself. This is noticeably overpriced nutrition and poor optimization for some game projects. Of course, RX Vega 64 is an entry into the Hi-End segment of video cards, but, in general, it does not have overwhelming advantages over competitors, for example, an excellent non-reference solution, for example, the same ASUS ROG Stris GeForce GTX 1080 OC — and consumes less , and costs less, and is not inferior in performance.
In general, the Radeon RX Vega 64 looks like a solution for ardent fans of the “red” camp, but the ASUS ROG Stris RX Vega 64 OC is an excellent non-reference solution that deserves attention.
ASUS ROG Strix RX Vega 64 OC wins «Best Choice» non-reference Radeon RX Vega 64 award. : Test & Review: ASUS ROG Strix Radeon Vega 64 OC Edition — Alternative Design Graphics Card
We’ve been waiting a long time for the first Radeon RX Vega 64 with an alternative design, but the card has finally arrived in our test lab. ASUS was the first to introduce a corresponding video card, and we were the first to have it. It will be very interesting to see what improvements ASUS has been able to make with the ROG Strix Radeon Vega 64 OC Edition graphics card, what advantages we will get compared to the reference version.
Video cards Radeon RX Vega 64 and Vega 56 have been waiting for a very long time, the expectations of users were very high. We published a test of the reference version, where we also disassembled the Vega architecture. We also conducted additional tests of High Bandwidth Memory Controller, cryptocurrency mining and overclocking. Finally, the reduced voltage test gave some very interesting results.
But before we get into the graphics card review, let me say a few words about the situation around the alternate design Radeon RX Vega models. At Computex, some AMD partners were talking about the graphics cards being available in September or October. As usual, at first only video cards came out in reference versions. We expected AMD partners to ship their graphics cards with a slight delay after the reference releases. But this did not happen.
The only graphics card announced so far is the ROG Strix Radeon Vega 64 OC Edition. It is available in the final design, but ASUS explained to us that it will not be possible to buy a video card before October. Moreover, it is not entirely clear what is meant: the beginning, middle or end of October. For the ROG Strix Radeon Vega 56, no date has been given at all.
In the meantime, we have received comments from some AMD partners about the status of alternative design models. Apparently, AMD planned to start shipping GPUs to its partners from September 11th so they could start producing graphics cards with alternative designs. But AMD has delayed deliveries indefinitely. Partners are still in a state of confusion, because they do not know when I can start producing video cards.
But back to the ASUS ROG Strix Radeon Vega 64 OC Edition video card. As usual, we’ll start with the specs.
|Model:||ASUS ROG Strix Radeon Vega 64 OC Edition|
|Manufacturer website:||ASUS ROG Strix Radeon Vega 64 OC Edition (ROG-STRIX-RXVEGA64-O8G-GAMING)|
|Number of transistors:||12.5 billion|
|GPU clock speed (base)||1.298 MHz|
|GPU Clock Speed (Boost)||1.630 MHz|
|Memory frequency||945 MHz|
|Memory bus width||2.048 bit|
|Memory bandwidth||484 GB/s|
|Stream Processors||4. 096|
|Raster Operations Pipelines (ROP)||64|
|Typical power consumption:||—|
Recall that AMD set rather aggressive Boost frequencies for its reference versions, which were never achieved in practice. You could count on frequencies between 1.400 and 1.536 MHz, but no more. ASUS for the ROG Strix Radeon RX Vega 64 OC Edition has set the Boost frequency to 1.630 MHz, so it will be very interesting to see how the video card performs under load.
Otherwise, we did not receive technical distinctions in architecture. The Vega 10 GPU is used, which is manufactured using a 14nm process technology and contains 12.5 billion transistors. There are 4,096 stream processors available on the chip, running at the clock speeds mentioned above. Also available are 256 texture units and 64 raster operation pipelines. Note also the technical novelty of the Vega generation — 8 GB of HBM2 memory, which are connected via a 2.048-bit bus. With a clock speed of 945 MHz, we get a memory bandwidth of 484 GB / s.
Before we move on to the video card, let me give you the results of clock speeds under different loads. Thanks to the Boost mechanisms, graphics cards dynamically change clock speeds, so it is quite important to evaluate the real frequencies under load.
