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.

    Hello. I'm writing from the future and I bring important news about Google Stadia.

    " To make it possible on its servers, Google has combined an x86 processor (likely an Intel one) with hyperthreading that runs at 2.7GHz, with 16GB of RAM, and a custom AMD graphics chip. It’s said to uses HBM 2 and has 56 compute units, delivering enough raw horsepower for 10.7 TFlops.

    That sounds like a modified Vega 56, although it’s equally possible that it’s one of AMD’s upcoming Navi line of graphics cards."

    So my question is, can these be under-volted like Polaris can for some pretty decent power savings, and what is the power usage like when you enable AMD's Chill mode. They had stated you get about 90-95% of the performance but at a significantly lower power usage. Reply

    Does this means that all the future of VEGA 64 will rest in the hands of FINEWINE(tm)'s optimizations and boosts?

    Because right now Vega 64 is nothing but a disappointment.

    This is a letdown. I don't understand why AMD chooses to lag behind Nvidia. The market is ripe for a competitive alternative to Nvidia. AMD hasn't been it. I am very pleased with my GTX 1080 purchase in January. Hopefully, come my next GPU upgrade time, AMD will have something better to consider. Reply

    They don't "choose" to. They had the money to either make an amazing CPU, or an amazing GPU. And the CPU market is larger, so they chose to push R&D budget into Ryzen (Which has payed off big time). Reply

    They chose to split their resources between two GPUs (polaris and vega) rather then focusing on one line of chips. They chose to rebrand and resell the same chips for 5 years.

    AMD isnt rich, but they make quite a few boneheaded decisions.

    Actually, that looks like it paid off for them in market share. Also, Polaris was always out of stock (irrelevant as to the reasons why. It's still money in AMD's pocket). Reply

    That's a good point; whatever the buyer, a sale is still a sale. However, perhaps from AMD's pov they'd rather sell them to gamers because when Etherium finally crashes there will be a huge dump of used AMD cards on the market that will at least for a time stifle new card sales, whereas gamers tend to keep their cards for some time. Selling GPUs to miners now is certainly money in the bag, but it builds up a potential future sting. Reply

    I would never buy a used GPU that has been run at full throttle 24/7 for months. I'm sure some people won't understand what miners do with their cards or will be enticed by the prices anyway. Reply

    I own a wide range of 290s and 290xs I picked up at the end of the last mining craze for great prices. Purchased all off miners. They all still work to this day with 0 issues. I've also purchased and sold 10x that quantity across 280 - 290x. Of those only one failed and sapphire replaced it under end of warranty.

    I look forward to the new craze ending. Will get some great cards for dirt cheap, and a vast majority still under warranty.

    Nothing wrong with buying them.
