Packaging & Unboxing

Like most STRIX family products, the STRIX Radeon RX Vega56 comes in black packaging with a full-color image of the card on the front. The colorful STRIX logo splashes across most of the box.

The rear of the box is also in full color and highlights several of the important features of the card. Also listed are the ports on the rear of the card.

The edge of the box gives a quick rundown of specs in several languages.

The Sides of the box are pretty basic, only showing the brand and model of the card.

After taking off the outer sleeve of the Box, we find the inner box has the STRIX logo printed on it. Most of the other STRIX family products only have a black interior box.

Inside we find the typical folded packaging holding the driver disk and paperwork nestled securely in a pocket in the foam.

Under the top cover, we get our first look at the card. ASUS provides very secure packaging with several inches of foam around the card, and the included accessories in their own pocket nearby.

This is everything included with the card, some paperwork, a Driver disk, a dual 6-pin PCIe to single 8-pin PCIe adapter, and a pair of ROG-branded Velcro straps for cable management.

A Closer Look

The STRIX Radeon RX Vega56 sports the same triple fan, 2.5 slot, triple-fan cooling solution many of the recent STRIX line of cards have used previously and looks identical to its Vega 64 sibling.  RGB capable light bars run along the edges of the card blending into the angular outline.

The rear of the card will also look similar to other STRIX branded GPUs. A large ROG logo on the rear of the card lights up in your choice of RGB colors and effects along with the other side of the card. The brushed metal surface hides partially under a scratch protective film out of the box.

The rear of the card sports ASUS’s FanConnect II which includes dual 4-pin fan headers and an additional RGB header. Fan’s connected here will spin up after the card warms up, but can be controlled manually from software as well.

From the side you can see how massive the heatsink assembly is, taking up the entire typical 2-slot space all by itself even before the fans are strapped on top of this.

The rear sports a VR friendly set of video outputs, including a pair of HDMI 2.0 ports, a pair of DisplayPort 1.2 and a sole Dual Link DVI-D. You can also see from this vantage point how far the cooling solution extends towards the outside of your case, as well as creeping into the next expansion slot a bit.

There isn’t much to see on this side of the card, only the PCIe 3.0 x16 connection.

Power is provided by a pair of 8-pin PCIe connections for a total of 375W worth of power delivery including the PCIe slot.

It’s not readily obvious and is in fact quite easy to miss, but the STRIX Radeon Vega56 comes with 2 performance profiles, selectable by a very small switch near the STRIX logo on the side of the card. The positions are labeled ‘P’ for performance mode (240W TDP) and ‘Q’ for quiet mode (220W TDP).

An X shaped cutout in the backplate fits around the GPU cooling reinforcement bracket.

In the typical fashion with the STRIX line, the PCIe power connections have a pair of LED’s tied to each port. When the LED is white, the plug above has an 8-pin power connection properly connected, and red indicates a problem. A set of test points are on the rear of the card to measure critical voltages will be appreciated by overclockers looking to push this card to the breaking point.

The Light tubes sure do look great with nice even light from end to end.

Radeon WattMan

Radeon WattMan is AMD’s new groundbreaking power management utility that controls GPU voltage, engine clocks, memory clocks, fan speed and temperature1. Radeon WattMan is based on Radeon Software features but offers multiple new ways of precise overclocking controls. With the new control over voltage and per state frequency curve for GPU clocks, comprehensive tuning control is now available. With these new controls in Radeon WattMan, the extra benefit lies within the new ability to finely tune the exact experience for your games.

Using the new histogram which records and displays the GPU activity, clock speeds, temperature and fan speed, you can visualize and understand how the game/application runs in a single interface, and configure based on that captured data. This complements the initial Radeon Software Crimson Edition launch feature of per profile overclocking, where each detected game can have its own overclocked profile. On launch, that game profile’s overclocking settings will take effect, and on close, the overclocking settings revert back to the global defaults the user can also set.

Synthetic Testing & Performance

Futuremark 3DMark

3DMark includes everything you need to benchmark your PC and mobile devices in one app. Whether you’re gaming on a smartphone, tablet, notebook, or a desktop gaming PC, 3DMark includes a benchmark designed specifically for your hardware.

RELATED:  ASRock Z270 Extreme4 Motherboard Review

Our first test of the ASUS ROG Strix Vega56 is quite interesting. We keep having to double check our numbers against our previous results from our testing of the ASUS ROG Strix Vega64 as they are very close together. For example, our Vega64 run of the standard Firestrike scored 22786 points on the graphics segment, only around 1500 points more than here.

The split on Timespy between the Vega 64 and this Vega 56 is a bit further apart, but the Vega 56 does great here. 4K is still a little too heavy of a hit for good performance, but its common to see frame rates in the low 40’s here.


Futuremark VRMark

The performance requirements for VR games are much higher than for typical PC games. So if you’re thinking about buying an HTC Vive or an Oculus Rift, wouldn’t you like to know that your PC is ready for VR?

VRMark includes three VR benchmark tests that run on your monitor, no headset required, or on a connected HMD. At the end of each test, you’ll see whether your PC is VR ready, and if not, how far it falls short.

Orange Room Test – The Orange Room benchmark shows the impressive level of detail that can be achieved on a PC that meets the recommended hardware requirements for the HTC Vive and Oculus Rift. If your PC passes this test, it’s ready for the two most popular VR systems available today.

Cyan Room Test – Cyan Room is a DirectX 12 benchmark. It features a large, complex scene and many eye-catching effects. Cyan Room shows how using an API with less overhead can help developers deliver impressive VR experiences even on modest PC systems.

Blue Room Test – The Blue Room is a much more demanding test. It’s ideal for benchmarking the latest graphics cards. With its massive 5K rendering resolution and spectacular volumetric lighting effects, the Blue Room sets the bar for future hardware generations.

The Strix Vega 56 does admirably in both Orange and Cyan level VRMark tests, but it just a bit shy of a passing mark for the Blue Room test which comes in a 44 FPS. Overall, the Vega 56 powered card should do well in all but the most demanding VR titles.


Unigine Superposition

Extreme performance and stability test for PC hardware: video card, power supply, cooling system. Check your rig in stock and overclocking modes with a real-life load! Also includes interactive experience in a beautiful, detailed environment.

A lone professor performs dangerous experiments in an abandoned classroom, day in and day out. Obsessed with inventions and discoveries beyond the wildest dreams, he strives to prove his ideas.

Once you come to this place in the early morning, you would not meet him there. The eerie thing is a loud bang from the laboratory heard a few moments ago. What was that? You have the only chance to cast some light upon this incident by going deeply into the matter of quantum theory: thorough visual inspection of professor’s records and instruments will help to lift the veil on the mystery.


Running 1080p, even the extreme level test is no match for the Vega56 running the DirectX API, but OpenGL does still take a heavy hit. 4K optimized shows a solid score and a playable frame rate, but 8K is still out of reach for current generation GPU’s. Interestingly, at 1080P, the Vega 56 scores higher now than when we ran the Vega 64 through the same tests.

Game Testing & Performance

Ashes of the Singularity

Planet by planet, a war is raging across the galaxy. The technological singularity has given humanity the power to expand further than they ever have before. Now, they compete with each other and their sentient artificial intelligence adversaries for control of newfound worlds.

In Ashes of Singularity: Escalation, the Strix Vega 56 does a great job on the DX12 Extreme preset. The average frame rate of the 4K test dips to 51FPS, but the 1440p and 1080p tests maintain solid frame rates.

Compared to a range of current GPU’s, the Strix Vega 56 lands right around the more expensive Nvidia GTX 1070Ti cards, not bad at all.

Interestingly here, at 4K, the Vega 56 outpaces its Vega 64 counterpart. We tested the Strix Vega 64 right at launch, so at this point, it’s apparent AMD has made some significant gains in the terms of driver derived performance gains. Great hardware is one thing, but a solid software suite makes all the difference.

Dues Ex: Mankind Divided

The year is 2029, and mechanically augmented humans have now been deemed outcasts, living a life of complete and total segregation from the rest of society.

Now an experienced covert operative, Adam Jensen is forced to operate in a world that has grown to despise his kind. Armed with a new arsenal of state-of-the-art weapons and augmentations, he must choose the right approach, along with who to trust, in order to unravel a vast worldwide conspiracy.

At the Ultra preset level, the Strix Vega 56 provides solid frame rates up through 1440p, but 4K is just a little too heavy at this detail level.

Comparing to a few other cards, the Vega 56 does decently, outpacing the Vega 64 at 1080p thanks to stronger drivers currently, and is only a short distance behind its V64 counterpart.


Rise of the Tomb Raider

Rise of the Tomb Raider is an action-adventure video game developed by Crystal Dynamics and published by Square Enix. It is the sequel to the 2013 video game Tomb Raider, a reboot of the Tomb Raider franchise. It was released on Xbox One and Xbox 360 in November 2015 and for Microsoft Windows in January 2016. It is set to release for PlayStation 4 in the second half of 2016.

Rise of the Tomb Raider was officially announced in June 2014. The game’s storyline follows Lara Croft as she ventures into Siberia in search of the legendary city of Kitezh, whilst battling a paramilitary organization that intends on beating her to the city’s promise of immortality. Presented from a third-person perspective, the game primarily focuses on survival and combat, while the player may also explore its landscape and various optional tombs. Camilla Luddington returns to voice and performs her role as Lara.

Upon release, Rise of the Tomb Raider received positive reviews, with critics praising its graphics, gameplay, and characterization. It was the best-selling Xbox One game during Christmas week and had sold over one million copies by the end of 2015. Additional content was also released, including a new story campaign, a new gameplay mode, as well as new outfits and weapons for Lara.


Rise of the Tomb Raider proves to be quite playable at 1080p and 1440p, but you may want to knock the preset down a notch or two to stay in the 60 FPS range for 4K resolution.

At 1440p, we see the Vega 56 hot on the heels of the Vega 64, but overall, a bit behind Nvidia’s 1070 and above cards.

At glorious 4K, the gap closes quite a bit.


Grand Theft Auto: V

“When a young street hustler, a retired bank robber, and a terrifying psychopath find themselves entangled with some of the most frightening and deranged elements of the criminal underworld, the U.S. government and the entertainment industry, they must pull off a series of dangerous heists to survive in a ruthless city in which they can trust nobody, least of all each other.

Grand Theft Auto V for PC offers players the option to explore the award-winning world of Los Santos and Blaine County in resolutions of up to 4k and beyond, as well as the chance to experience the game running at 60 frames per second.”

Grand Theft Auto: V is the oldest game in our benchmark suite but still proves to be a heavy load on high settings and resolutions. The game offers players a huge range of PC-specific customization options, including over 25 separate configurable settings for texture quality, shaders, tessellation, anti-aliasing and more. It has the highest recommended system requirements in our game benchmark suite.


For as old as it is, Rockstar’s Grand Theft Auto V is still a demanding game with the settings turned up.  With very high settings applied, the Strix Vega 56 holds on to quite playable frame rates up to 4K resolution. The minimums dip heavily, clear down to around the 20 FPS mark, but averages are all well above 60 FPS even at 4K.

Compared to a few other cards, we again see driver optimizations helping the Vega 56 out quite a bit.


We were able to push the HBM2 memory to 960Mhz, a little less than our Vega 64 sibling, but even a modest overclock on the GPU core causes temps to creep out of the green zone and to start throttling which hurt scores more than helping. We never saw the card hit its own peak boost speeds during benchmark runs, mostly due to VRM thermals.

Power Draw and Temps


We did see the quiet mode show a maximum ‘GPU only power draw’ reported by GPU-Z as 221W while Performance Mode peaked out around 240W at stock. Opening up the power target and pushing the clocks a bit jumped the power draw to a peak of about 340W. Overall, about 20W less than its V64 counterpart across the board.

The GPU’s core temps stayed under about 65C under load in all conditions, often around the 61-62C mark with the fans at about 50% speed. Our real issue overclocking came from the VRM temps shooting up quickly to the 100C range and causing heavy throttling of the card, even with fan speeds set to 100% manually. With the VRM SOC temps above 90C, the core clock would fall back to around 1200MHz and the GPU memory would hover close to the 800Mhz mark while occasionally dropping to 500Mhz. If you leave it at stock, temps are quite good but any serious overclocking is going to require some better cooling love to the VRM, like water cooling.

The front half of the card around the GPU core and HBM2 memory seems to have solid cooling, but the rear of the card around the VRM stages gets hot quickly under full load conditions if you start pushing the clocks. This really isn’t a design flaw made by ASUS, it’s more of just trying to cram 300+ watts into something the size of a GPU and squeeze all that power through a handful of tiny surface mount components.


Final Thoughts & Conclusion

ASUS’s modifications to the Vega platform are great and really give the Vega56 room to breathe. AMD has done some significant updates to the drive suite since we checked out the ROG Strix Vega 64 a few months ago, and in turn, it makes the Vega 56 here beat its bigger brother in a few of our charts. Rest assured, the Vega 64 has also seen improvements. GPU availability is still low, but better than it was several months ago. Stock of a GPU online stays around for hours to days now, not seconds to minutes. Prices are still inflated quite a bit, but you can still snag a deal here and there with a little searching around.

While the driver updates have unlocked quite a bit of previously unrealized potential, 4K at max settings is just out of reach most of the time. If you are willing to back off the settings just a hair, it’s certainly doable, and any lower resolution will do great. If VR is your thing, the STRIX Vega56 OC can probably handle your favorite games on current VR headsets, but upcoming 2nd generation sets are going to be even more demanding.

We hate to let you down in the overclocking section of any review, but ASUS’s latest firmware for this card has it tuned about as well as it can be. There is plenty left under the hood for the adventurous overclocking who is willing to slap a water block on here, but for the rest of us, ASUS provides a well-tuned and optimized product right out of the box and its hard to fault them for that. If you can get your hands on one for close to the MSRP and avoid the scalpers pricing of $800+, it’s a tough card to beat.

Great job ASUS!
