The AMD Radeon R9 Fury X Review: Aiming For the Top
by Ryan Smith on July 2, 2015 11:15 AM ESTSynthetics
As always we’ll also take a quick look at synthetic performance. Since Fiji is based on the same GCN 1.2 architecture as Tonga (R9 285), we are not expecting too much new here.
First off we have tessellation performance. As we discussed in greater detail in our look at Fiji’s architecture, AMD has made some tessellation/geometry optimizations in GCN 1.2, and then went above and beyond that for Fiji. As a result tessellation performance on the R9 Fury X is even between than the R9 285 and the R9 290X, improving by about 33% in the case of TessMark. This is the best performing AMD product to date, besting even the R9 295X2. However AMD still won’t quite catch up to NVIDIA for the time being.
As for texture fillrates, the performance here is outstanding, though not unexpected. R9 Fury X has 256 texture units, the most of any single GPU card, and this increased texture fillrate is exactly in line with the theoretical predictions based on the increased number of texture units.
Finally, the 3DMark Vantage pixel fillrate test is not surprising, but it is none the less a solid and important outcome for AMD. Thanks to their delta frame buffer compression technology, they see the same kind of massive pixel fillrate improvements here as we saw on the R9 285 last year, and NVIDIA’s Maxwell 2 series. At this point R9 Fury X’s ROPs are pushing more than 40 billion pixels per second, a better than 2x improvement over the R9 290X despite the identical ROP count, and an important reminder of the potential impact of the combination of compression and HBM’s very high memory bandwidth. AMD’s ROPs are reaching efficiency levels simply not attainable before.

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.

oh believe me i remember they felt bad lol but im not ragging on amd but nvidia stole their thunder with the 980 tiKateH - 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.

To be fair the 5950 ultra was actually decentMorawka - 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.

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.
