We’ve seen the architecture. We’ve seen the teasers. We’ve seen the Frontier. And we’ve seen the specifications. Now the end game for AMD’s Radeon RX Vega release is finally upon us: the actual launch of the hardware. Today is AMD’s moment to shine, as for the first time in over a year, they are back in the high-end video card market. And whether their drip feeding marketing strategy has ultimately succeeded in building up consumer hype or burnt everyone out prematurely, I think it’s safe to say that everyone is eager to see what AMD can do with their best foot forward on the GPU front.

Launching today is the AMD Radeon RX Vega 64, or just Vega 64 for short. Based on a fully enabled Vega 10 GPU, the Vega 64 will come in two physical variants: air cooled and liquid cooled. The air cooled card is your traditional blower-based design, and depending on the specific SKU, is either available in AMD’s traditional RX-style shroud, or a brushed-aluminum shroud for the aptly named Limited Edition.

Meanwhile the Vega 64 Liquid Cooled card is larger, more powerful, and more power hungry, utilizing a Radeon R9 Fury X-style external radiator as part of a closed loop liquid cooling setup in order to maximize cooling performance, and in turn clockspeeds. You actually won’t see AMD playing this card up too much – AMD considers the air cooled Vega 64 to be their baseline – but for gamers who seek the best Vega possible, AMD has put together quite a stunner.

Also having its embargo lifted today, but not launching until August 28th, is the cut-down AMD Radeon RX Vega 56. This card features lower clockspeeds and fewer enabled CUs – 56 out of 64, appropriately enough – however it also features lower power consumption and a lower price to match. Interestingly enough, going into today’s release of the Vega 64, it’s the Vega 56 that AMD has put the bulk of their marketing muscle behind.

Between these SKUs, AMD is looking to take on NVIDIA’s longstanding gaming champions, the GeForce GTX 1080 and the GeForce GTX 1070. In both performance and pricing, AMD expects to be able to bring NVIDIA’s cards to a draw, if not pulling out a victory for Team Red. This means we’ll see the $500 Vega 64 set against the GTX 1080, while the $400 Vega 56 goes up against the GTX 1070. At the same time however, the dark specter of cryptocurrency mining hangs over the gaming video card market, threatening to disrupt pricing, availability, and the best-laid plans of vendors and consumers alike. Suffice it to say, this is a launch like no other in a time like no other.

Overall it has been an interesting past year and a half to say the least. With a finite capacity to design chips, AMD’s decision to focus on the mid-range market with the Polaris series meant that the company effectively ceded the high-end video card market to NVIDIA once the latter’s GeForce GTX 1080 and GTX 1070 launched. This has meant that for the past 15 months, NVIDIA has had free run of the high-end market. Meanwhile AMD’s efforts to focus on the mid-range market to win back market share meant that AMD initially got the jump on NVIDIA in this market by releasing Polaris ahead of NVIDIA’s answer, and their market share has recovered some. However it’s a constant fight against the dominating NVIDIA, and one that’s been made harder by essentially being invisible to the few high-end buyers and the many window shoppers. That is a problem that ends today with the launch of the Vega 64.

I’d like to say that today’s launch is AMD landing a decisive blow in the video card marketplace, but the truth of the matter is that while AMD PR puts on their best face, there are signs that behind the scenes things are more chaotic than anyone would care for. Vega video cards were originally supposed to be out in the first-half of this year, and while AMD technically made that with the launch of the Vega Frontier Edition cards, it’s just that: a technicality. It was certainly not the launch that anyone was expecting at the start of 2017, especially since some of Vega’s new architectural functionality wasn’t even enabled at the time.

More recently, AMD’s focus on product promotion and on product sampling has been erratic. We’ve only had the Vega 64 since Thursday, giving us less than 4 days to completely evaluate the thing. Adding to the chaos, Thursday evening AMD informed us that we’d receive the Vega 56 on Friday, and encouraging us to focus on that instead. The reasoning behind this is complex – I don’t think AMD knew if it could have Vega 56 samples ready, for a start – but ultimately boils down to AMD wanting to put their best foot forward. And right now, the company believes that the Vega 56 will do better against the GTX 1070 than the Vega 64 will do against the GTX 1080.

Regardless, it means that we’ve only had a very limited amount of time to evaluate the performance and architectural aspects of AMD’s new cards, and even less time to write about them. Never mind chasing down interesting odds & ends. So while this is a full review of the Vega 64 and Vega 56, there’s some further investigating left to do once we recover from this blitz of a weekend and get our bearings back.

So without further ado, let’s dig into AMD return to the high-end market with their Vega architecture, Vega 10 GPU, and the Vega 64 & Vega 56 video cards.

    I would love to see a proper comparison between an AMD Ryzen 7 and an Intel i7-7700k at this point with Vega to see how they compare, rather than testing only on an Intel based system, since the 299X is still somewhat new. All of the Ryzen launch reviews were done on a new platform, and the AMD 370X is mature enough where reviews will be done with a lot more information. Vega is a bit of a question mark in terms of how well it does when you compare between the two platforms. Even how well drivers should have matured in how well the 370X chipset deals with the Geforce 1080 is worth looking at in my opinion.

    I've had the thought, without resources, that NVIDIA drivers may not do as well on an AMD based machine compared to an Intel based machine, simply because of driver issues, but without a reasonably high end video card from AMD, there has been no good way to do a comparison to see if some of the game performance differences between processors could have been caused by NVIDIA drivers as well.

    well, I was expected lower performance compared to a geforce 1080 so this is one of the few plusses. Now NVIDIA only has to bump the base clocks for the Geforce 1080 while still consuming less power. Competition is great but this is not the best product from AMD, on 14nm the gains should be much higher. Fortunately AMD is great now on CPU's and that will hopefully bring income that should be invested in GPU research.
    Good luck AMD

    NV doesn't have to do anything as long as retail pricing has the 1080 so much cheaper. I look foward to seeing how the 56 fares. Reply

    It looks like the 1080 MSRP is actually less! Other sites mentioning the initial price included a $100 rebate which has expired :( and the new MSRP has taken effect....

    Remember your last paragraph after the game engines adopt AMD's architecture and features, of which they have committed themselves in doing, and already partially in development. When that happens I look forward to you asking what the hell went wrong at Nvidia. Reply

    The whole "game engines will adopt AMD's architecture" thesis was made when the Xbox One and PS4 were released in 2013. Since then, AMD's market share among PC gamers has declined considerably and NVIDIA seems to be doing just fine in terms of features and performance in relevant game engines. The XBox One and PS4 architectures account for a significant percentage of total software sales. Vega architecture will account for a minuscule percentage. So why would the thesis hold true for Vega when it didn't hold true for Sea Islands?

    Besides, NVIDIA has had packed FP16 capability since 2015 with the Tegra X1. They also have it in their big GP100 and GV100 GPUs. They can relatively easily implement it in consumer GeForce GPUs whenever they feel it is appropriate. And within 3 months of doing so they will have more FP16-enabled gaming GPUs in the market than Vega will represent over its entire lifespan.

    That means the Nintendo Switch is FP16 capable, by the way. Reply

    "the Xbox One and PS4 were released in 2013. Since then, AMD's market share among PC gamers has declined considerably "

    The problem AMD had was they could not play to their advantage - which was having a CPU and GPU. The CPU was so aweful that nobody used them to game (or very few) now that Ryzen is here and successful they will gain GPU share even though their top cards dont beat Nvida. This is called "Attach Rate" - when a person buys a Computer with an AMD CPU the get an AMD GPU 55% of the time vs 25% of the time with an Intel CPU. AMD had the same issue with their APU - the CPU side was so bad that nobody cared to build designs around them but now with Raven Ridge coming Ryzen/Vega they will do very well there as well.

    I wouldn't expect bulldozer (or whatever their latest pre-zen architecture was called) attach rates to hold true for Ryzen. There were probably a significant percentage of AMD fans accounting for bulldozer sales. If Ryzen is a lot more successful (and by all accounts it looks like it will be), then only a small percentage of Ryzen sales will be by die hard AMD fans. Most will be by people looking to get the best value. Then you can expect attach rates for AMD GPUs with Ryzen CPUs to be significantly lower than with bulldozer. Reply
