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.

I thought it was great as well.. It had a lot more meat to it then I was expecting. Ryan might have been late to the party but he's getting more feedback than most other sites on his review so that shows that it was highly anticipated.B3an - Saturday, July 4, 2015 - link
I don't understand why the Fury X doesn't perform better... It's specs are considerably better than a 290X/390X and it's memory bandwidth is far higher than any other card out there... yet it still can't beat the 980 Ti and should also be faster than it already is compared to the 290X. It just doesn't make sense.just4U - Saturday, July 4, 2015 - link
Early drivers and perhaps the change over into a new form of memory tech has a bit of a tech curve that isn't fully realized yet.Oxford Guy - Saturday, July 4, 2015 - link
Perhaps DX11 is holding it back. As far as I understand it, Maxwell is more optimized for DX11 than AMD's cards are. AMD really should have sponsored a game engine or something so that there would have been a DX12 title available for benchmarkers with this card's launch.dominopourous - Saturday, July 4, 2015 - link
Great stuff. Can we get a benchmarks with these cards overclocked? I'm thinking the 980 Ti and the Titan X will scale much better with overclocking compared to Fury X.Mark_gb - Saturday, July 4, 2015 - link
Great review. With 1 exception.Once again, the 400 AMP number is tossed around as how much power the Fury X can handle. But think about that for one second. Even a EVGA SuperNOVA 1600 G2 Power Supply is extreme overkill for a system with a single Fury X in it, and its +12V rail only provides 133.3 amps.
That 400 AMP number is wrong. Very wrong. It should be 400 watts. Push 400 Amps into a Fury X and it most likely would literally explode. I would not want to be anywhere near that event.

The operating voltage of the Fury chip is probably around 1V, so 400A sounds correct (1V*400A = 400W).meacupla - Saturday, July 4, 2015 - link
okay, see, it's not 12V * 400A = 4800W. It's 1V (or around 1V) * 400A = 400W4800W would trip most 115VAC circuit breakers, as that would be 41A on 115VAC, before you even start accounting for conversion losses.

Anyone hear about Nvidia lowering thier graphics quality to get a higher frame rate in reviews vs Fury? Reference is semi accurate forum 7/3 (Nvidia reduces IQ to boost performance on 980TI? )sa365 - Sunday, July 5, 2015 - link
I too would like to know more re:bugsy1939 comment.Have Nvidia been caught out with lower IQ levels forced in the driver?
