Almost 7 years ago to this day, AMD formally announced their “small die strategy.” Embarked upon in the aftermath of the company’s struggles with the Radeon HD 2900 XT, AMD opted against continuing to try beat NVIDIA at their own game. Rather than chase NVIDIA to absurd die sizes and the risks that come with it, the company would focus on smaller GPUs for the larger sub-$300 market. Meanwhile to compete in the high-end markets, AMD would instead turn to multi-GPU technology – CrossFire – to offer even better performance at a total cost competitive with NVIDIA’s flagship cards.

AMD’s early efforts were highly successful; though they couldn’t take the crown from NVIDIA, products like the Radeon HD 4870 and Radeon HD 5870 were massive spoilers, offering a great deal of NVIDIA’s flagship performance with smaller GPUs, manufactured at a lower cost, and drawing less power. Officially the small die strategy was put to rest earlier this decade, however even informally this strategy has continued to guide AMD GPU designs for quite some time. At 438mm2, Hawaii was AMD’s largest die as of 2013, still more than 100mm2 smaller than NVIDIA’s flagship GK110.

AMD's 2013 Flagship: Radeon R9 290X, Powered By Hawaii

Catching up to the present, this month marks an important occasion for AMD with the launch of their new flagship GPU, Fiji, and the flagship video card based on it, the Radeon R9 Fury X. For AMD the launch of Fiji is not just another high-end GPU launch (their 3rd on the 28nm process), but it marks a significant shift for the company. Fiji is first and foremost a performance play, but it’s also new memory technology, new power optimization technologies, and more. In short it may be the last of the 28nm GPUs, but boy if it isn’t among the most important.

With the recent launch of the Fiji GPU I bring up the small die strategy not just because Fiji is anything but small – AMD has gone right to the reticle limit – but because it highlights how the GPU market has changed in the last seven years and how AMD has needed to respond. Since 2008 NVIDIA has continued to push big dies, but they’ve gotten smarter about it as well, producing increasingly efficient GPUs that have made it harder for a scrappy AMD to undercut NVIDIA. At the same time alternate frame rendering, the cornerstone of CrossFire and SLI, has become increasingly problematic as rendering techniques get less and less AFR-friendly, making dual GPU cards less viable than they once were. And finally, on the business side of matters, AMD’s market share of discrete GPUs is lower than it has been in over a decade, with AMD’s GPU plus APU sales now being estimated as being below just NVIDIA’s GPU sales.

AMD's Fiji GPU

Which is not to say I’m looking to paint a poor picture of the company – AMD Is nothing if not the perennial underdog who constantly manages to surprise us with what they can do with less – but this context is important in understanding why AMD is where they stand today, and why Fiji is in many ways such a monumental GPU for the company. The small die strategy is truly dead, and now AMD is gunning for NVIDIA’s flagship with the biggest, gamiest GPU they could possibly make. The goal? To recapture the performance crown that has been in NVIDIA’s hands for far too long, and to offer a flagship card of their own that doesn’t play second-fiddle to NVIDIA’s.

To get there AMD needs to face down several challenges. There is no getting around the fact that NVIDIA’s Maxwell 2 GPUs are very well done, very performant, and very efficient, and that between GM204 and GM200 AMD has their work cut out for them. Performance, power consumption, form factors; these all matter, and these are all issues that AMD is facing head-on with Fiji and the R9 Fury X.

At the same time however the playing field has never been more equal. We’re now in the 4th year of TSMC’s 28nm process and have a good chunk of another year left to go. AMD and NVIDIA have had an unprecedented amount of time to tweak their wares around what is now a very mature process, and that means that any kind of advantages for being a first-mover or being more aggressive are gone. As the end of the 28nm process’s reign at the top, NVIDIA and AMD now have to rely on their engineers and their architectures to see who can build the best GPU against the very limits of the 28nm process.

Overall, with GPU manufacturing technology having stagnated on the 28nm node, it’s very hard to talk about the GPU situation without talking about the manufacturing situation. For as much as the market situation has forced an evolution in AMD’s business practices, there is no escaping the fact that the current situation on the manufacturing process side has had an incredible, unprecedented effect on the evolution of discrete GPUs from a technology and architectural standpoint. So for AMD Fiji not only represents a shift towards large GPUs that can compete with NVIDIA’s best, but it represents the extensive efforts AMD has gone through to continue improving performance in the face of manufacturing limitations.

And with that we dive in to today’s review of the Radeon R9 Fury X. Launching this month is AMD’s new flagship card, backed by the full force of the Fiji GPU.

With 4096 SPs and coupled with the first implementation of High Bandwidth Memory, the R9 Fury X aims for the top. Over the coming pages we’ll get in to a deeper discussion on the architectural and other features found in the card, but the important point to take away right now it that it packs a lot of shaders, even more memory bandwidth, and is meant to offer AMD’s best performance yet. R9 Fury X will eventually be joined by 3 other Fiji-based parts in the coming months, but this month it’s all about AMD’s flagship card.

The R9 Fury X is launching at $649, which happens to be the same price as the card’s primary competition, the GeForce GTX 980 Ti. Launched at the end of May, the GTX 980 Ti is essentially a preemptive attack on the R9 Fury X from NVIDIA, offering performance close enough to NVIDIA’s GTX Titan X flagship that the difference is arguably immaterial. For AMD this means that while beating GTX Titan X would be nice, they really only need a win against the GTX 980 Ti, and as we’ll see the Fury X will make a good run at it, making this the closest AMD has come to an NVIDIA flagship card in quite some time.

Finally, from a market perspective, AMD will be going after a few different categories with the R9 Fury X. As competition for the GTX 980 Ti, AMD is focusing on 4K resolution gaming, based on a combination of the fact that 4K monitors are becoming increasingly affordable, 4K Freesync monitors are finally available, and relative to NVIDIA’s wares, AMD fares the best at 4K. Expect to see AMD also significantly play up the VR possibilities of the R9 Fury X, though the major VR headset, the Oculus Rift, won’t ship until Q1 of 2016. Finally, it has now been over three years since the launch of the original Radeon HD 7970, so for buyers looking for an update AMD’s first 28nm card, Fury X is in a good position to offer the kind of generational performance improvements that typically justify an upgrade.

    You don't need architecture improvements to use DX12/Vulkan/etc. The APIs merely allow you to implement them over DX11 if you choose to. You can write a DX12 game without optimizing for any GPUs (although, not doing so for GCN given consoles are GCN would be a tad silly).

    If developers are aiming to put low level stuff in whenever they can than the issue becomes that due to AMD's "GCN everywhere" approach developers may just start coding for PS4, porting that code to Xbox DX12 and than porting that to PC with higher textures/better shadows/effects. In which Nvidia could take massive performance deficites to AMD due to not getting the same amount of extra performance from DX12.

    Don't see that happening in the next 5 years. At least, not with most games that are console+PC and need huge performance. You may see it in a lot of Indie/small studio cross platform games however.

    AMD is getting there but, they still have a little bit to go to bring us a new "9700 Pro". That card devastated all Nvidia cards back then. That's what I'm waiting for to come from AMD before I switch back.
  • Thatguy97 - Thursday, July 2, 2015 - link

    would you say amd is now the "geforce fx 5800"
  • piroroadkill - Thursday, July 2, 2015 - link

    Everyone who bought a Geforce FX card should feel bad, because the AMD offerings were massively better. But now AMD is close to NVIDIA, it's still time to rag on AMD, huh?

    That said, of course if I had $650 to spend, you bet your ass I'd buy a 980 Ti.
  • Thatguy97 - Thursday, July 2, 2015 - link

    oh believe me i remember they felt bad lol but im not ragging on amd but nvidia stole their thunder with the 980 ti
  • KateH - Thursday, July 2, 2015 - link

    C'mon, Fury isn't even close to the Geforce FX level of fail. It's really hard to overstate how bad the FX5800 was, compared to the Radeon 9700 and even the Geforce 4600Ti.

    The Fury X wins some 4K benchmarks, the 980Ti wins some. The 980Ti uses a bit less power but the Fury X is cooler and quieter.

    Geforce FX level of fail would be if the Fury X was released 3 months from now to go up against the 980Ti with 390X levels of performance and an air cooler.
  • Thatguy97 - Thursday, July 2, 2015 - link

    To be fair the 5950 ultra was actually decent
  • Morawka - Thursday, July 2, 2015 - link

    your understating nvidia's scores.. the won 90% of all benchmarks, not just "some". a full 120W more power under furmark load and they are using HBM!!
  • looncraz - Thursday, July 2, 2015 - link

    Furmark power load means nothing, it is just a good way to stress test and see how much power the GPU is capable of pulling in a worst-case scenario and how it behaves in that scenario.

    While gaming, the difference is miniscule and no one will care one bit.

    Also, they didn't win 90% of the benchmarks at 4K, though they certainly did at 1440. However, the real world isn't that simple. A 10% performance difference in GPUs may as well be zero difference, there are pretty much no game features which only require a 10% higher performance GPU to use... or even 15%.

    As for the value argument, I'd say they are about even. The Fury X will run cooler and quieter, take up less space, and will undoubtedly improve to parity or beyond the 980Ti in performance with driver updates. For a number of reasons, the Fury X should actually age better, as well. But that really only matters for people who keep their cards for three years or more (which most people usually do). The 980Ti has a RAM capacity advantage and an excellent - and known - overclocking capacity and currently performs unnoticeably better.

    I'd also expect two Fury X cards to outperform two 980Ti cards with XFire currently having better scaling than SLI.
  • chizow - Thursday, July 2, 2015 - link

    The differences in minimums aren't miniscule at all, and you also seem to be discounting the fact 980Ti overclocks much better than Fury X. Sure XDMA CF scales better when it works, but AMD has shown time and again, they're completely unreliable for timely CF fixes for popular games to the point CF is clearly a negative for them right now.
