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.

    it is fault of marketing team, who's else? If your engineering produce VW Golf only idiot in your PR can tout "Ferrari F1!"
    good job by marketing team would be to set realistic expectations for the product, which they didn't for Vega. Polaris is hardly a competition for 1080ti nor Titan but does it make it bad product? Did marketing overhype and overshot Polaris?
    So as they did good with Polaris they screwed up horribly with Vega.

    Yeah I'm totally sure they'll look to RandoCommenter3769 for marketing advice next time around. Reply

    Or they should rush it for a different kind of disaster like X299, X370?? I'm happy with it just like it is but I've already accumulated everything else and don't need to buy the whole ecosystem. Just the the PCB and an EK block, but maybe they will offer it with threadripper then I can dump my x1800 and Asus crossfire VI. Hey, it's just money. Reply

    August 14th.....what the heck are they waiting for at this point. Release date two weeks after "announcement" they sure have taken their sweet time bringing this to market.

    The Green Team seems to be dragging their feet on Volta as well.

    Staggering product launches is the way it has to be done to make money. I will never forget the Intel/Nvidia tick tock rip off the consumer scheme. For what I payed for my 6700k at launch I could now have a 8 core 16 thread 64 PCIE lane threadripper that would be the last CPU I'd ever have to buy. I've dreamed of 64 pcie lanes for a long time. I can wire my whole home with dedicated GPUs for each TV. WOW. Can you imagine what that kind of bandwidth will inspire mfgs to build. THANK YOU AMD. Reply

    "THANK YOU AMD."

    What's sad is that Intel could have done this ages ago, re the true nature of the 3930K, the 4820K having 40 lanes, etc. Shows what lack of competition does. Just glad AMD is back kick Intel where it's rightly deserved.

    > The Green Team seems to be dragging their feet on Volta as well.

    Because they don't need to bother pushing when their "competitor" has just released an architecture that is slower than NVIDIA's own more-than-1-year-older Pascal.

    NVIDIA literally needs to do nothing to torpedo Vega, but if they really wanted to put the screws on they could drop the price of all their cards by $50 and watch as AMD squirms.

    Cutting prices would just hurt Nvidia. Vega isn't going to sell either way. Reply

    I would bet my entire setup that Vega pre-orders will fill up instantly and the cards will be next to impossible to find through at least the end of August. Reply

    If you're betting that based on mining demand, it's not gonna happen with Vega's ridiculously poor efficiency. Reply
