For AMD’s Radeon Technologies Group, 2018 was a bit of a breather year. After launching the Polaris architecture in 2016 and the Vega architecture in 2017, for 2018 AMD set about to enjoy their first full year of Vega. Instead of having to launch a third architecture in three years, the company would focus on further expanding the family by bringing Vega's laptop and server variants to market. And while AMD's laptop efforts have gone in an odd direction, their Radeon Instinct server efforts have put some pep back in their figurative step, giving company the claim to the first 7nm GPU.

Following the launch of a late-generation product refresh in November, in the form of the Radeon RX 590, we had expected AMD's consumer side to be done for a while. Instead, AMD made a rather unexpected announcement at CES 2019 last month: the company would be releasing a new high-end consumer card, the Radeon VII (Seven). Based on their aforementioned server GPU and positioned as their latest flagship graphics card for gamers and content creators alike, Radeon VII would once again be AMD’s turn to court enthusiast gamers. Now launching today – on the 7th, appropriately enough – we're taking a look at AMD's latest card, to see how the Radeon VII measures up to the challenge.

On the surface, the Radeon VII would seem to be straightforward. The silicon underpinning the card is AMD's Vega 20 GPU, a derivative of the original Vega 10 that has been enhanced for scientific compute and machine learning, and built on TSMC's cutting-edge 7nm process for improved performance. An important milestone for AMD's server GPU efforts – it's essentially their first high-end server-class GPU since Hawaii all the way back in 2013 – AMD has been eager to show off Vega 20 throughout the later part of its bring-up, as this is the GPU the heart of AMD’s relatively new Radeon Instinct MI50 and MI60 server accelerators.

First and foremost designed for servers then, Vega 20 is not the class of GPU that could cheaply make its way to consumers. Or at least, would seem to be AMD's original thought. But across the aisle, something unexpected has happened: NVIDIA hasn't moved the meter very much in terms of performance-per-dollar. The new Turing-based GeForce RTX cards instead are all about features, looking to usher in a new paradigm of rendering games with real-time raytracing effects, and in the process allocating large parts of the already-large Turing GPUs to this purpose. The end result has been relatively high prices for the GeForce RTX 20 series cards, all the while their performance gains in conventional game are much less than the usual generational uplift.

Faced with a less hostile pricing environment than many were first expecting, AMD has decided to bring Vega 20 to consumers after all, dueling with NVIDIA at one of these higher price points. Hitting the streets at $699, the Radeon VII squares up with the GeForce GTX 2080 as the new flagship Radeon gaming card.

Looking at our specification table, Radeon VII ships with a "peak engine clock" of 1800MHz, while the official boost clock is 1750MHz. This compares favorably to RX Vega 64's peak engine clock, which was just 1630MHz, so AMD has another 10% or so in peak clockspeed to play with. And thanks to an open air cooler and a revised SMU, Radeon VII should be able to boost to and sustain its higher clockspeeds a little more often still. So while AMD's latest card doesn't add more ROPs or CUs (it's actually a small drop from the RX Vega 64), it gains throughput across the board.

However, if anything, the biggest change compared to the RX Vega 64 is that AMD has doubled their memory size and more than doubled their memory bandwidth. This comes courtesy of the 7nm die shrink, which sees AMD's latest GPU come in with a relatively modest die size of 331mm2. The extra space has given AMD room on their interposer for two more HBM2 stacks, allowing for more VRAM and a wider memory bus. AMD has also been able to turn up the memory clockspeed up a bit as well, from 1.89 Gbps/pin on the RX Vega 64 to a flat 2 Gbps/pin for the Radeon VII.

Interestingly, going by its base specifications, the Radeon VII is essentially a Radeon Instinct MI50 at heart. So for AMD, there's potential to cannibalize Instinct sales if the Radeon VII's performance is too good for professional compute users. As a result, AMD has cut back on some of the chip's features just a bit to better differentiate the products. We'll go into more a bit later, but chief among these is that the card operates at a less-than-native FP64 rate, loses its full-chip ECC support, and naturally for a consumer product, it uses the Radeon Software gaming drivers instead of the professional Instinct driver stack.

Of course any time you're talking about putting a server GPU in to a consumer or prosumer card, you're talking about the potential for a powerful card, and this certainly applies to the Radeon VII. Ultimately, the angle that AMD is gunning for with their latest flagship card is on the merit of its competitive performance, further combined with its class-leading 16GB of HBM2 memory. As one of AMD's few clear-cut specification advantages over the NVIDIA competition, VRAM capacity is a big part of AMD's marketing angle; they are going to be heavily emphasizing content creation and VRAM-intensive gaming. Also new to this card and something AMD will be keen to call out is their triple-fan cooler, replacing the warmly received blower on the Radeon RX Vega 64/56 cards.

Furthermore, as a neat change, AMD is throwing their hat into the retail ring as a board vendor and directly selling the new card at the same $699 MSRP. Given that AIBs are also launching their branded reference cards today, it's an option for avoiding inflated launch prices.

Meanwhile, looking at the competitive landscape, there are a few items to tackle today. A big part of the mix is (as has become common lately) a game bundle. The ongoing Raise the Game Fully Loaded pack sees Devil May Cry 5, The Division 2, and Resident Evil 2 included for free with the Radeon VII, RX Vega and RX 590 cards. Meanwhile the RX 580 and RX 570 cards qualify for two out of the three. Normally, a bundle would be a straightforward value-add against a direct competitor – in this case, the RTX 2080 – but NVIDIA has their own dueling Game On bundle with Anthem and Battlefield V. In a scenario where the Radeon VII is expected to trade blows with the RTX 2080 rather than win outright, these value-adds become more and more important.

The launch of the Radeon VII also marks the first product launch since the recent shift in the competitive landscape for variable refresh monitor technologies. Variable refresh rate monitors have turned into a must-have for gamers, and since the launch of variable refresh technology earlier this decade, there's been a clear split between AMD and NVIDIA cards. AMD cards have supported VESA Adaptive Sync – better known under AMD's FreeSync branding – while NVIDIA desktop cards have only supported their proprietary G-Sync. But last month, NVIDIA made the surprise announcement that their cards would support VESA Adaptive Sync on the desktop, under the label of 'G-Sync Compatibility.' Details are sparse on how this program is structured, but at the end of the day, adaptive sync is usable in NVIDIA drivers even if a FreeSync panel isn't 'G-Sync Compatible' certified.

The net result is that while NVIDIA's announcement doesn't hinder AMD as far as features go, it does undermine AMD's FreeSync advantage – all of the cheap VESA Adaptive Sync monitors that used to only be useful on AMD cards are now potentially useful on NVIDIA cards as well. AMD of course has been quite happy to emphasize the "free" part of FreeSync, so as a weapon to use against NVIDIA, it has been significantly blunted. AMD's official line is one of considering this a win for FreeSync, and for freedom of consumer choice, though the reality is often a little more unpredictable.

The launch of the Radeon VII and its competitive positioning against the GeForce RTX 2080 means that AMD also has to crystalize their stance on the current feature gap between their cards and NVIDIA's latest Turing machines. To this end, AMD's position has remained the same on DirectX Raytracing (DXR) and AI-based image quality/performance techniques such as DLSS. In short, AMD's argument goes along the lines that they believe that the performance hit and price premium for these features isn't worth the overall image quality difference. In the meantime, AMD isn't standing still, and along with DXR fallback drivers, they working on support for WinML and DirectML for their cards. The risk to AMD being, of course, is that if DXR or NVIDIA's DLSS efforts end up taking off quickly, then the feature gap is going to become more than a theoretical annoyance.

All told, pushing out a 7nm large gaming GPU for consumers now is a very aggressive move so early in this process' lifecycle, especially as on a cyclical basis, Q1 is typically flat-to-down and Q2 is down. But in context, AMD doesn't have that much time to wait and see. The only major obstacle would be pricing it to be acceptable for consumers.

That brings us to today's launch. For $699, NVIDIA has done the price-bracket shifting already, on terms of dedicated hardware for accelerating raytracing and machine learning workloads. For the Radeon VII, the terms revolve around 16GB HBM2 and prosumer/content creator value. All that remains is their gaming performance.

    thirded on still enjoying SupCom! i have however long ago given up on attempting to find the ultimate system to run it. i7 920 @ 4.2Ghz, nope. FX-8150 @ 4.5Ghz, nope. The engine still demands more CPU for late-game AI swarms! (and i like playing on 81x81 maps which makes it much worse)
  • Korguz - Friday, February 8, 2019 - link

    Holliday75 and KateH

    ive run supcom on a i7 930 OC'd to 4.2 on a 7970, slow as molasses late in the game VS the AI, and on my current i7 5930k and strix 1060 and.. same thing.. very slow late in the game.... the later patches supposedly helped the game use more then 1 or 2 cores, i think Gas Powered games called it " multi core aware "

    makes me wonder how it would run on something newer like a threadripper, top en Ryzen or top end i7 and an i9 with a 1080 + vid card though, compared to my current comp....
  • eva02langley - Friday, February 8, 2019 - link

    Metal Gear Solid V, Street Fighter 5, Soulcalibur 6, Tekken 7, Senua Sacrifice...

    Basically, nothing from EA or Ubisoft or Activision or Epic.

    Oh oh! Would you be willing to post some FLOSS benchmarks? Xonotic, 0AD, Openclonk and Supertuxkart?
  • Manch - Friday, February 8, 2019 - link

    I would like to see a mixture of games that are dedicated to a singular API, and ones that support all three or at least two of them. I think that would make for a good spread.
  • Manch - Thursday, February 7, 2019 - link

    Not sure that I expected more. The clock for clock against the V64 is telling. @$400 for the V64 vs $700 for the VII, ummm....if you need a compute card as well sure, otherwise, Nvidia got the juice you want at better temps for the same price. Not a bad card, but it's not a great card either. I think a full 64CU's may have improved things a bit more and even put it over the top.

    Could you do a clock for clock compare against the 56 since they have the same CU count?? I'd be curious to see this and extrapolate what a VII with 64CU's would perform like just for shits and giggles.
  • mapesdhs - Friday, February 8, 2019 - link

    Are you really suggesting that, given two products which are basically the same, you automatically default to NVIDIA because of temperatures?? This really is the NPC mindset at work. At least AMD isn't ripping you off with the price, Radeon VII is expensive to make, whereas NVIDIA's margin is enormous. Remember the 2080 is what should actually have been the 2070, the entire stack is a level higher than it should be, confirmed by die code numbers and the ludicrous fact that the 2070 doesn't support SLI.

    Otoh, Radeon II is generally too expensive anyway; I get why AMD have done it, but really it's not the right way to tackle this market. They need to hit the midrange first and spread outwards. Stay out of it for a while, come back with a real hammer blow like they did with CPUs.

    Well, they're not basically the same. Who's the NPC LOL? I have a V64 in my gaming rig. It's loud but I do like it for the price. The 2080 is a bit faster than the VII for the same price. It does run cooler and quieter. For some that is more important. If games is all you care about, get it. If you need compute, live with the noise and get the VII.

    I don't care how expensive it is to make. If AMD could put out a card at this level of performance they would and they would sell it at this price.
    Barely anyone uses SLI/Crossfire. It's not worth it. I previously had 2 290X 8GB in Crossfire. I needed a beter card for VR, V64 was the answer. It's louder but it was far cheaper than competitors. The game bundle helped. Before that, I had bought a 1070 for the wife's computer. It was a good deal at the time. Some of yall get too attached to your brands get all frenzied at any criticism. I buy what suits my needs at the best price/perf.

    Not our fault AMD decided to make a video card with more expensive components and not beat the competition,
