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.

    Regardless of the competitive landscape, we shouldn't applaud this kind of dragged out, train wreck of a marketing job, ending in an embarrassing product release.

    For the future, I suggest one piece of advice: "Put up, or shut up".

    It's not the marketing department's fault: the architecture is just junk. They did the best they could with the severe delays, and have tried to put lipstick on a pig. I don't know how you can hold it against the marketing department. It's the engineers who clearly need to get their act together.
  • Walletripper - Monday, July 31, 2017 - link

    I wouldn't exactly call it junk. Just look at where AMD has come from. Now you can get an 8 core 16 thread 64PCIE lane processor for probably around $500 at Microcenter and a $300 plus 4k graphics card that will go excellent with a low cost freesync monitor. If AMD had failed you would be paying $4 grand for a setup like that. AMD now offers that for around $1500 very soon. Intel will counter and AMD will counter then it's time to buy. A year ago I never dreamed that I would be able to afford such hardware and I will never forget the Intel tick tock rip off marketing. I will only buy AMD from now on. If you are smart you will also.

    Sometimes the ironing on AT is beyond delicious.

    Do you really expect intelligence from AMD fanbois? Good luck with that.
  • tuxRoller - Monday, July 31, 2017 - link

    If you nixed the AMD part, you'd might be right though I'd choose to say objectivity, or good judgement since I not aware of good data linking intelligence with fanboiosity.

    LOL. Oh, the IRONY of this statement.

    Amd cpu's and gpu's come from what are essentially different companies. Amd spun Radeon graphics off in to Radeon Technology Group. Most likely to insulate the parent corporation in the event that the Radeon group fails and needs to be sold to the highest bidder.
  • Nagorak - Monday, July 31, 2017 - link

    The Vega that's being presented is not a 4K card. Performance just isn't there. Even 1080 Ti struggles at 4K. But the icing on the cake is that the 1080 Ti puts out much more performance than RX Vega, while still seemingly using less power.

    I've been a supporter of AMD for a long time, but this is just pathetic.

    "I will only buy AMD from now on. If you are smart you will also."

    Bravo. I had been buying Intel and NVidia because AMD was technically inferior (worst in CPUs). But thinking about Ryzen, what it takes to create something like that, and AMD's chronic near-bankruptcy, I realized that we are damned lucky they have survived and are still punching. My money now goes to (1) Reward the people who are *really* trying and (2) Keep them in the game.

    Do you assume AMD can pull off such a recovery twice? If too many of us say "yeah, but I can get a few more FPS from an Intel / NVidia rig", we could very well have only those two in the future.

    The bottom line: Don't niggle about minor tech differences; there's much more at stake. Buy AMD where you reasonably can - and they do offer a LOT now. I bought Ryzen 1800X and will buy Vega.
