At this point, one must give credit to AMD for their marketing program for the Radeon RX Vega. The company has opted to drip feed information over many months, and as a result this has kept the public interested in the architecture and consumer RX Vega cards. Since it was by name back in the spring of 2016, we’ve had architecture previews, product teasers, and even a new Frontier Editions to tide us over.  Suffice it to say, there’s a great deal of fascination in finally seeing the products AMD has been beating the drums about for so long.

To that end, there’s good news today and there’s bad news today. In the interest of expediency, I may as well start with the bad news: today is not the launch day for the Radeon RX Vega. In fact, only right before this embargo expired did AMD even announce a launch date: August 14th. So for reviews, performance analyses, and of course purchasing, everyone will have to hold on just a bit longer.

The good news then is that even if today isn’t the Radeon RX Vega launch, AMD is finally making significant progress towards it by announcing the cards, the specifications, and the pricing. Gamers may not be able to buy the cards quite yet, but everyone is going to have some time to size up the situation before the proper launch of the cards next month. Overall this situation is very similar to the unveiling of the Radeon R9 290 series, where AMD announced the cards at a product showcase before launching them the following month.

So without further ado, let’s dive into the Radeon RX Vega family of cards and their specifications.

All told, AMD will be releasing 3 different RX Vega cards. All 3 cards are based on the same GPU, Vega 10, which powers the already released Radeon Vega Frontier Edition. So if you’re familiar with that card, then you should have an idea of what to expect here.

The top of AMD’s lineup is the Radeon RX Vega 64 Liquid Cooled Edition. This is a fully enabled Vega 10 card and it has the highest clockspeeds and highest power requirements of the stack. All told, this is 64 CUs, 64 ROPs, boosting to 1677MHz, and paired with 8GB of HBM2 memory clocked at 1.89Gbps. Typical board power for the card is rated at 345W. To cool such a card, you of course will want liquid cooling, and living up to the name the card, AMD has included just that, thanks to a pump and 120mm radiator.

The second member of AMD’s lineup is the shorter-named vanilla Radeon RX Vega 64. Unlike its liquid cooled predecessor, this is a traditional blower-type air cooled card. And for the purposes of AMD’s product stack, the company is treating the vanilla Vega 64 as the “baseline” card for the Vega 64 family. This means that the company’s performance projections are based on this card, and not the higher-clocked liquid cooled card.

The vanilla Vega 64 utilizes the same fully enabled Vega 10 GPU, with 64 CUs and 64 ROPs. The card’s reduced cooling capacity goes hand-in-hand with slightly lower clockspeeds of 1247MHz base and 1546MHz boost. Paired up with the Vega GPU itself is the same 8GB of HBM2 as on the liquid cooled card, still running at 1.89Gbps for 484GB/sec of memory bandwidth. Finally, this card ships with a notably lower TBP than the liquid cooled card, bringing it down by 50W to 295W.

Meanwhile, unlike any of the other cards in the RX Vega family, the Vega 64 will come in two shroud design options. AMD’s reference shroud is a plastic/rubber design similar to what we saw on the reference Radeon RX 480 launched last year. AMD will also have a “limited edition” version of the card with the same hardware specifications, but replacing the rubber shroud with a brushed aluminum shroud, very similar to the one found on the Vega Frontier Edition. Though it’s important to note that the only difference between these two cards is the material of the shroud; the cards are otherwise identical, PCBs, performance, cooling systems, and all.

On that note, AMD has only released a limited amount of information on the cooler design of the Vega 64, which is of particular interest as it’s an area where AMD struggled on the R9 290 and RX 480 series. We do know that the radial fan is larger, now measuring 30mm in radius (60mm in diameter). The fan in turn is responsible for cooling a heatsink that’s attached to the Vega 10 GPU + memory package via a vapor chamber, a typical design choice for high performance, high TDP video cards.

Finally, the last member of the RX Vega family is the Radeon RX Vega 56. The obligatory cut-down member of the group, this card gets a partially disabled version of the Vega 10 GPU with only 56 of 64 CUs enabled. On the clockspeed front, this card also sees reduced GPU and memory clockspeeds; the GPU runs at 1156MHz base and 1471MHz boost, while the HBM2 memory runs at 1.6Gbps (for 410GB/sec of memory bandwidth). Following the traditional cut-down card model, this lower performing card is also lower power – and quite possibly the most power efficient RX Vega card – with a 210W TDP, some 85W below the Vega 64. Meanwhile, other than its clockspeed the card’s HBM2 memory is untouched, shipping with the same 8GB of memory as the other RX Vega members.

Moving on, perhaps the burning question for many readers now that they have the specifications in hand is expected performance, and this is something of a murky area. AMD has published some performance slides for the Vega 64, but they haven’t taken the time to extensively catalog what they see as the competition for the card and where the RX Vega family fits into that. Instead, what we’ve been told is to expect the Vega 64 to “trade blows” with NVIDIA’s GeForce GTX 1080.

In terms of numbers, the few numbers that the company has published have focused on minimum framerates over average framerates, opting to emphasize smoothness and the advantage they believe to have over the aforementioned GTX 1080. As always, competitive numbers should be taken with a (large) grain of salt, but for the time being this is the best guidance we have on what to expect for the RX Vega family’s performance.

Otherwise for the Vega 64 Liquid and Vega 56, we don’t have any other performance figures. Expect the former to outperform the air cooled Vega 64 – though perhaps not massively – while the Vega 56 will come in notably lower.

    Wait, what? Trading blows with the 1080, and not the 1080 Ti? I thought flagship Vega was supposed to offer 1080 Ti+ performance for less money. I was also hoping the cut-down version for $400 would be very comparable to 1080 Ti, like R9 290 (non X) was to big Kepler. Not to mention cut-down HBM2, only 64 ROPs; the $400-500 4K dream looks more and more like a mirage.

    Am I missing something here? Weren't those cards supposed to be 12+ TF and 10+ TF - way more than 1080 and 1070?

    In gpu same price gpu from amd and Nvidia has always been about the same speed.
    So now we have vega64 that is 500$ vs Nvidia 1080 about 500$ and They Are about the same speed. Is anyone surprised? No I did not think so. Vega will manage better in dx12 and Vulcan titles and Nvidia will beat Vegas in dx11 titles hands down... any surprices in there... no at all. This is very much what we did and can Expect.

    When Volta will come out, it is more expensive than 1080 series if it is faster. If it is not faster it is about the same price (I predict that Volta is much faster in dx12 and Vulcan titles, but not so much in dx11.. it can even be slover in there compared to previous generation.)
    All in all both companies have put the price quite close the Comparative product from the rival and it will continue Also in the future.

    I am very happy about the Vega. The competition is back. Not Volta will have to compete against Vega and not against very old fury. And very soon after Volta comes out there will be Vega 2. The Navi is at least two years from now. If it is not, and Navi comes 2018, then Nvidia have some problems untill 2019 the will get out Volta2. But all in all the relative price vs. Competition will remain the same. regardless what is released.

    Not necessarily true. When NVIDIA released Kepler (600-series), they decided to start charging double - $500 for a mid-sized GPU, instead of $250; and $1000 for the flagship in the face of Titan a bit later on. It was then that AMD shook up the market by releasing R9 290 - a $400 Titan alternative; at the time, the closest competitor NVIDIA had was 780 - a double cut-down big Kepler that was slower than R9 290 and cost $700. Obviously, all that was great for consumers, even those that weren't looking to buy AMD since NVIDIA cut the price of 780 and introduced 780 Ti.

    I was hoping for something similar with Vega.

    I think everyone was hoping for that. Unfortunately, something appears to have gone seriously wrong with Vega, hence the long delays. Reply

    Ah you say they have to price at same levels right? But AMD can undercut Intel by half with much better cpu, but cannot undercut NV??
    You talking out of your finger.
    Most probable reason for that is expensive big die and HBM2

    No, you're not missing anything. The Vega architecture just sucks. It's a step back in every way from Fiji and Polaris. Reply

    Does anyone remember the time when AMD released a card that was actually faster than the top NVIDIA card and didn't draw a lot more power? Or was it ATI? Reply

    So how are those air coolers going to cool 300W? Would it not have been smarter to just release the water cooled card and let partners release the air cooled ones with custom monster 3 slot coolers? As it is all the Vega reviews will be with an air cooled Vega's, and everyone's memory of it will be "too hot, too loud, throttles hard". See 290 release for comparison. Reply

    It would have been smarter just not to release the gaming version at all, just said Vega gaming got cancelled and pushed the work station cards. Reply

    AMD most likely couldn't do that due to stockholder obligations. Reply
