Asus ROG STRIX RX VEGA 56 OC Edition - Its all about that Raw Unadulterated Power

The wait was finally over last year when AMD rolled out the much awaited Vega cards for consumers in form of the RX VEGA 56 and RX VEGA 64 that not only are their first prominent step in the right direction but also after ages pose a real threat to their Nvidia counterparts in the main-stream division dethroning the GTX 1070 & placing the VEGA 56 in between the GTX 1070 and the GTX 1080 performance bracket! While the RX Vega 56 has been extremely successful and wooed in many enthusiasts and gamers including the ones who were beholden to a particular brand.
Thanks to Asus India I have with me today their latest Asus ROG STRIX RX Vega 56 OC Edition Graphics card for review which is as the name suggest the overclocked version of the Vega 56 and hosts a ton of other features including the ROG branding to say the least.

Asus RX Vega 56 OC Edition comes as one of the two cards that are based on the latest CGN 5.0 14nm FinFET architecture and have the Vega 10 GPU at their heart the same as that of the Vega 64, with 56 out of the total 64 compute units enables hence the name Vega 56 and has 3584 steam processor cores compared to the 4096 as that on the Vega 64. Apart from this the number of TMUs and ROPS are same on both models as 224 and 64 respectively. Our GPU today is clocked in at 1590Mhz boost which is 119Mhz over the reference model while the 20148 bus width 8GB HBM2 memory is at 800Mhz effective just like that on the reference edition so no changes there. All these tweaks give the Asus ROG STRIX RX Vega 56 OC a massive bandwidth of 410GB/s which is enough to handle any title in quad HD resolution.

What's in the Box!?

Asus brings the ROG STRIX RX Vega 56 OC Edition in a big-heavy cardboard box which is mainly black in color with hints of green on the sides. The STRIX and Vega logo along with the graphics card image occupy most of the real estate on the packing while the Aura and VR ready logos are printed clearly at the bottom and the very top right side. At the top left corner we can find the signature 'R' logo which was all started by the Vega Frontier Edition to complete the whole package.

On the back side the box boasts about the 3 years warranty that the card comes with along with various technical and physical features that the RX Vega 56 comes loaded with such as the patented fan blade design, two times more contact area for the cooler, Aura sync etc.


Inside the outer cover you will find a big black box with the STRIX logo printed right in the center. Open this and you get a small envelop nestled inside a foam cavity under which the RX Vega 56 OC rests in a thick foam block wrapped in an anti static plastic bag.

On the accessories front the box included the Asus ROG STRIX RX Vega 56 OC Edition Graphics Card along with the driver DVD, user manual and two ROG velcro cable ties. All in all the packaging is to the point and protective enough to keep this beefy card safe and secure during transit.

Take a Closer Look

The RX Vega 56 from Asus is an elegant looking card with an all black matte finish and a triple fan design which looks old but is infact an all new cooler design to keep this card cool even under extreme loads.

This unit weights in at 1.5Kg and measures in at 29.8x13.4x5.25 cm making it one of the longest and thickest cars you can find on the market today. Infact the card occupies two and a half expansion slots so keep this in mind before buying this card as it can pose an issue for ITX users going for a compact build.
Basally this is the same DirectCU cooler in size, design and specifications as that on the Asus ROG STRIX GTX 1080 Ti cards so as to provide the best cooling experience to this unit since we all know that there is a lot of hot and heavy technology under that hood to be cooled.


At the back the backplate is smooth with a X shaped retention bracket and is decorated with abstract designs all over the surface and the Asus and STRIX logo near the top end. We also find the ROG eye logo at one corner which is RGB LED lit and imparts the signature ROG look to this RX Vega 56 from Asus.

The Asus ROG STRIX RX Vega 56 OC will offer five display connectors; you'll spot two 1.2 certified Display Ports, two HDMI 2.0b connectors and a DVI port. The dual HDMI arrangement is done with VR in mind.
This sort of arrangement enables 4K displays at 120Hz, 5K displays at 60Hz, and 8K displays at 60Hz (using two cables) making the RX Vega 56 the best in class for UHD gaming, VR Gaming, recording and streaming purposes.

The ROG STRIX RX Vega 56 uses a triple fan cooling solution with new IP5X dust resistant patented fan design for better-reliable cooling and air flow experience. There are six heatpipes embedded inside the thick aluminum heatsink, which is divided into two parts, with a nickle plated copper base that makes 40% more contact with the GPU surface for more efficient cooling with lower noise levels.  Since the Vega 56 is rated at 210 TDP this sort of arrangement is more than enough to keep this card cool even under intense load with enough headroom for overclocking which enabled Asus to release this OC Edition.
These fans don't spin at upto 55°C and after that they start spinning in an ordered fashion with the right one spinning first followed by the center fan and then the last left fan when the temperature reached above 60°C to eliminate unnecessary noise. It is also sounds and looks kind of cool to me so a few extra brownie points for this kind of implementation.


At the bottom side the entire graphics card is clean with no heatpipe or anything protruding outside of the huge plastic shroud but just the PCIe connector at one end. While at the top we can see ssupport for power connectors and SLI connectors, yes you can even SLI this monster if you have the need and money well more of money than need I'd say!

The rear houses the RGB header and two extra fan headers that will spin attached chassis fans at the graphics card fan RPM. These fan headers have been carried forward from the precious generation design of Asus STRIX and ROG cards and do a great job in not only providing some much needed fan headers but also are a life saver when working in tight environments such as ITX builds with less space and lesser fan headers on the motherboard! However the use of the RGB header is still questionable since connecting a RGB strip to this header and routing it through the chassis is going to both difficult and impractical.


Due to the heavy and beefy nature of this card Asus has reinforced the entire cooling solution and PCB with a steel bracket cum heatsink that originated from the IO plate and run through the entire area of the PCB aswell as the cooler to impart that much needed tensile strength to avoid the graphics card from sagging under its own weight.

To power the Asus ROG STRIX RX Vega 56 OC Edition we have a two 8-pin PCIe power connectors on top which make it capable of withdrawing 375W on paper which is more than enough or sort of an overkill for a card rated at 210W TDP. This much power is enough to tweak the card for some further overclocking hopefully but it would definitely contribute to excessive heat generation if left at stock settings! Also Asus provides ts signature white LEDs on these connectors which light up and are static when the wires are properly connected and not those power phase activity lights as that on the reference design.

Benchmarks and Overclocking

Installing the Asus ROG STRIX RX Vega 56 OC Edition was easy and it powered up like a breeze once we booted up the system.
GPUZ reported the correct frequencies with 1590Mhz on the clock and 800Mhz on the memory.
For benchmarking the graphics card our new test bench was as follows -

CPU: Intel Core i7 5930K @4.5Ghz
Motherboard: Gigabyte X99 Gaming 5P
RAM: Kingston HyperX Predator 16GB DDR4 3000Mhz
Cooler: Cooler Master MasterLiquid Maker 240 
Graphics Card: Asus ROG STRIX RX VEGA 56 OC Edition

Storage: Corsair Neutron XTi 480GB
Power Supply: Cooler Master MasterWatt Lite 700
Case: Corsair Carbide SPEC Omega
OS: Windows 10 Pro 64-bit

Now overclocking the RX Vega 56 is not like what we usually do with other cards, we just can't dial up the voltages and add in some increments to the clocks till we start seeing screen tearing, dots or system crashes, that won't work here or well not work in an optimum manner. These RX Vega cards depend a lot upon thermals so much as so that you would find a different temperature reading for the card and another on just for the HBM memory on board which has a dedicated threshold of around 85°C. With that being said I firstly started by under volting the card and at -12% I managed a perfect balance of temperature threshold, fan noise and performance gains. At this stage the performance boost was significant at around 9°C drop in maximum temperatures.
Secondly I tried to overclock this already overclocked card at the same -12% power limit and was surprised to have obtained a stable 1670Mhz on the clock and 810Mhz on the memory while keeping the fans at auto as that's what most people would do and not like to have a jet plane inside their chassis! At this point I would like to mention that if I kept the power limit same and increased the clocks or increased the power limit and tried to overclock the card the frequencies that I managed were less or nearly the same respectively but with a lot of heat generation and I had to turn on the fans to 70% to keep the temperatures under check. Keep notice that if you follow this route the performance gains are not that great and you get a very high power drawn along with annoying fan noises all the time!
So be it any RX Vega card and in our case the Asus ROG STRIX RX Vega 56 OC edition would work great if under volted with significant performance boost even if you leave the clocks as they are, its just that you have to tune and find that sweet spot for your card that goes well with your requirements. Our benchmarks today would be at stock and at what we achieved on overclock that is at 1670Mhz clock and 810Mhz on memory.

AIDA64 Extreme edition GPGPU

The AIDA64 GPGPU test not only calculates the read, write and copy speed of the graphics card and processor but is also very useful in observing the SHA-1 Hash and AES-256 score. These are indications of how well the GPU can handle number crunching or real life image or video rendering. Higher score shows a better card.

3DMark Fire Strike & Time Spy

Fire Strike and Time Spy by 3D Mark is a test suit that plays a cinematic scene to determine the FPS, GPU temperature and CPU temperature scaling everything via a cumulative score. It is a great tool to benchmark your GPU since the render is mostly GPU & memory dependent.

Forza Horizon 3 is an open world racing video game developed by Playground Games and published by Microsoft Studios for Xbox One and Microsoft Windows 10. The game features cross-platform play between the two platforms and is heavily demanding when it comes to PC resources. Our settings are at ultra preset with FPS cap removed.

Noise & Temperature 

The fans on the Asus ROG STRIX RX Vega 56 OC Edition don't spin till the card hits 55°C or more. We recorded the maximum temperature in Celsius that our card hit during extensive gaming & sound was measured in decibels from a distance of 3 feet. This was performed for both stock and overclocked speeds.

My Verdict  

AMD is back and its back for good with the RX Vega series namely as the RX Vega 56 over the 64 since the former delivers around 10% low performance with significantly lower power consumption, heat generation and can be tweaked to almost the same level with a much lower price point.
With that being said I come back to the Asus ROG STRIX RX Vega 56 OC Edition in hand today and boy this is a beast of a card and when I say that I don't refer to the sheer physical size but also to the raw performance & the feature bundle that it comes with. This card can easily mow down any GTX 1070 in the market and even some of the GTX 1070 Tis including those from third party manufacturers in some titles and synthetic benchmarks by its out of the box frequency itself and Adrenaline driver which would obviously get better with time considering the new HBM2 memory that these Vega10 GPUs rely upon. Asus chose the cooler well for its STRIX RX Vega 56 OC and came up with something that delivers impressive performance at low temperatures and minimal noise along with additional fan headers and RGB headers, in case you need them.
Talking about its overclocking potential I'd say that the RX Vega 56 largely depends upon how you handle the voltages on this card and with the Super Alloy Power II components as Asus likes to call them we see a significant boost in performance by simply lowering down the power limit as the power delivery components on board handle everything seamlessly to yield the best possible combination. Even when it comes to increasing clock frequencies the card is not a slouch and I was surprised that I managed to add some extra Mhz on this already overclocked unit all of which was handled by the DirectCU cooler lets say in a cool manner!
Some might argue that the power consumption on any RX Vega 56 is high compared to that on the GTX 1070 or even above models but I say that the Vega 56 is winner when you consider the fact that it offers seamless 1440p gaming performance at a lower price point and saves you another heafty spending through the much cheaper FreeSync monitors. Also with 10.5TFLOPs under the hood the RX Vega 56 beats the GTX 1070 and GTX 1080 that offer just 6.5TFLOPs and 8.9TFLOPs respectively which obviously won't matter in gaming but when you use softwares that actually use that power like Adobe Premier Pro etc then the RX Vega 56 would out shine its competition by a huge margin.

Pros - 

• Good gaming performance
• Solid build quality 
• Runs cool and quiet under load
• Higher bandwidth from HBM2 proves helpful at high resolution
• Can be easily tweaked further for better performance  
• Compatible Freesync monitors come at no extra cost

Cons - 

• High power consumption  
• Unstable pricing and availability

I give it a 8/10 earning our Gold Award!
