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.

    Thank you, I already did. Not everywhere is cheap electricity.
  • Gigaplex - Tuesday, August 15, 2017 - link

    A little over $30 per year extra. I tend to upgrade on a 3 year cadence. That's around $100 extra I can use to bump up to the Nvidia card.
  • Outlander_04 - Tuesday, August 15, 2017 - link

    The highest cost for electricity I can see in the US is 26 cents per kilowatt hour.
    The difference in gaming power consumption is 0.078 Kilowatts hour Meaning it would take 12.8 hours to burn that extra kW/H
    Two hours of full load gaming every day adds up to 730 hours a year means 57 kW/H's extra for a total cost of $14.82 per year .
    In states with electricity cost of 10 cents kW/H the difference is about $5.70 a year

    You might have to save a bit longer than you expect .

    Why did you assume he was interested in the 1070/Vega 56? Comparing the 1080 FE with the Vega 64 air cooled, the difference is .150 kilowatts. At your same assumption of 2 hours a day and 26 cents a kilowatt-hour it comes to $28.50 a year, right in line with his estimate. It's not a stretch to think he would game more than 730 hours a year, either.
  • Outlander_04 - Thursday, August 17, 2017 - link

    The BF1 power consumption difference between Vega 64 and the 1080 FE is 0.08 kW/H.
    Not sure where you get your numbers from , but it is not this review .
    The numbers are essentially the same as I suggested above . 0.078 vs 0.080 .

    Less than $6 a year in states with lower utility costs and as much as $15 a year in Hawaii .
    Yes you could game more than 14 hours a week . Its also not a stretch to think you might game a lot less . What was your point?
  • HollyDOL - Friday, August 18, 2017 - link

    I don't know where you look, but 1080 FE system is taking 310W, Vega 64 then 459W, which is 149W for no gain whatsoever.
  • Outlander_04 - Friday, August 18, 2017 - link

    379 vs 459 watts for the 1080 fe vs Vega 64.
    delta is 0.08 kW/H
    Those figures are right here in this review on the gaming power consumption chart.
  • HollyDOL - Saturday, August 19, 2017 - link

    Lol man, you need to reread that chart. 379W is 1080Ti FE, not 1080FE.
  • FourEyedGeek - Tuesday, August 22, 2017 - link

    What if you live in a hot part of the world? Extra heat equals extra throttling, during the summer I reduce my OCs due to this. Slap on the air conditioning and it'll run a bit extra too to compensate costing more.

    I'd look at undervolting if possible a VEGA 56
  • ET - Tuesday, August 15, 2017 - link

    So Vega 72 yet to come? Page 2 says that there are 6 CU arrays of 3 CU's each. That's 18 CU's, with only 16 enabled in Vegz 64.
