The AMD Radeon RX Vega 64 & RX Vega 56 Review: Vega Burning Bright
by Ryan Smith & Nate Oh on August 14, 2017 9:00 AM ESTWe’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.

First? lolFireSnake - Monday, August 14, 2017 - link
Good! Now, let us read this in peace :)coolhardware - Monday, August 14, 2017 - link
Exactly. I am VERY excited to read about this, especially since AMD has been dragging this launch out for what seems forver.While reading I will also have another window open furiously refreshing http://amzn.to/2hZ9iPb (shortened URL for direct amd vega search on Amazon!) to see when they come in stock, and if we can get one before they sell out! ;-)
WOW, just checked and NewEgg is already out of EVERY Vega SKU :-( Like 15 different models from various brands :-( Bummer and I bet 80% are miners!

BestBuy sold out of all of their SKUs as well. :-(Targon - Monday, August 14, 2017 - link
I ran into the Out of Stock, auto-notify on Newegg for hours....and suddenly one showed up that I could actually buy. So, I hit it, and it has been in packaging for the past five hours. Amazon really messed up with the Ryzen launch, allowing far more orders than the expected number of Ryzen 7 chips, to the point where it took several additional weeks before some of them shipped out. That is why I won't order a highly anticipated item from Amazon.Manch - Tuesday, August 15, 2017 - link
I ordered the Oculus package, the $399 one from Amazon on July 12th. They shipped the controllers two days ago. headset is out of stock until further notice. It was in stock when I ordered. Then it was all orders before July 15th will be filled first. Then it was the touch controllers are out of stock. Then the touch controllers ship but the headset is out of stock. Aggravating to say the least. They are one of the few that ships electronics to APO without being shitty about it or charging triple of actual costs.coolhardware - Tuesday, August 15, 2017 - link
Way to stick with it! Did Best buy complete your order? Fingers crossed for you :-)rtho782 - Monday, August 14, 2017 - link
I think the GTA5 1440p benchmarks and the BF1 load power consumption graphs made me laugh the most.I guess it's a pretty effective space heater. Maybe they want to discourage crypto mining by using more power to make it unprofitable.
It's a shame, we need more competition. *sigh*

295 watts..?!?!?! Currently my whole system only pulls about 225 watts even when torture testing. That testing is only including CPU and RAM but other articles say my RX460 is about 104 watts during torture testing. So if I was stress testing CPU, RAM and video card all at once I'd be at around 329. Not a gamer myself but its hard for me to imagine over 500 watts for my system. Just doesn't make any sense in this day and age.Kratos86 - Monday, August 14, 2017 - link
Hmm you either don't understand how crypto mining works or what a joke is. Cryptominers generally turn the GPU clock down because it isn't very useful in these situations, even bandwidth isn't as relevant as latency. These cards with a bit of tweaking are getting 35 mh/s at $35 for $500. The Vega 56 blows the 64 away but both GPU's beat the RX 580 in terms of bang for buck and that's considering they haven't been optimised for mining performance yet.If these things hit 40 at $500 a piece, two for $1000, thats 80 mh/s for less than a Titan XP which at a cost of $1370 does around 37 mh/s. Saving $50 a year on power consumption and paying double the price for that privilege is not a very intelligent way to do things.
Suffice to say if you want one of these at the prices they are supposed to be selling at, you might get lucky and find one sometime this year because you are not finding these GPU's at these prices anytime soon and thats if they aren't sold out at any price. Unless AMD do something to get this in stock and keep it in stock the next few months are going to suck if you want one of these at prices that aren't inflated.
I guess AMD could have worst problems than "cryptominers keep buying our GPUs faster than we can make them" but it's still a situation they need to remedy.
