Synthetics

As always we’ll also take a quick look at synthetic performance. Since R9 Fury is a cut-down and lower clocked Fiji part, what we’re expecting here is a significant shader/texture hit, with a much smaller hit to tessellation and pixel throughput.

Synthetic: TessMark, Image Set 4, 64x Tessellation

TessMark scores more or less perfectly scale with clockspeed in this case. The R9 Fury is almost precisely 5% behind the R9 Fury X.

Synthetic: 3DMark Vantage Texel Fill

Synthetic: 3DMark Vantage Pixel Fill

As for 3DMark Vantage, the performance hits are in-line with expectations. The R9 Fury takes a pretty significant hit to texturing performance due to the combination of lost texture units and the clockspeed reduction, while pixel throughput trails by just under 5%. This indicates that at least for the purposes of the 3DMark test, the R9 Fury series is ROP bottlenecked rather than memory bandwidth bottlenecked, a consequence of AMD’s excellent delta color compression.

    I'd love to see these two go at it again once dx12 games start showing up.

    Bingo... :-). I bet the whole Fury lineup will gain a lot with DX12, especially the X2 part (4 + 4 GB won't equal 4 as in current CF). The are clearly CPU limited at this point.

    I don't know...

    Getting dx12 performance at the cost of dx11 performance sounds like a stupid idea this soon before dx12 games even come out.

    By the time a good amount of dx12 games come out there will probably be new graphics cards available.

    They will probably circle around and optimize things for 1080p and dx11, once dx12 and 4k is at a good place.

    DX12 games are out now. DX12 does not degrade DX11 performance. In fact Radeon 290x is 33% faster than 980 Ti in DX12. Fury X just CRUSHES ALL nVIDIA silicon with DX12 and there is a reason for it.

    Dx11 can ONLY feed data to the GPU serially and sequencially. Dx12 can feed data Asynchronously, the CPU send the data down the shader pipeline WHEN it is processed. Only AMD has this IP.

    Kindly provide link to a single DX12 game that is "out now".

    In every single review of the GTX 980 Ti there is this slide of DX12 feature set that the GTX 980 Ti supports and in that slide in all the reviews "Async Compute" is right there setting in the open, so I'm not really sure what do you mean by "Only AMD has this IP"!

    I'd strongly recommend that you hold your horses till DX12 games starts to roll out, and even then, don't forget the rocky start of DX11 titles!

    Regarding the comparison you're referring to, that guy is known for his obsession with mathematical calculations and synthetic benchmarking, given the differences between real-world applications and numbers based on mathematical calculations, you shouldn't be using/taking his numbers as a factual baseline for what to come.

    You are an idiotic person, wishful think and dreams don't make you correct. As stated please provide a link to these so called DX12 games and your wonderful "Fury X just CRUCHES ALL NVidia" statement.

    As long as there is separate RAM in PCs, memory argument is moot, as contents are still copied and executed on in two places.

    Negative. Once Graphic data is processed and sent to the shaders it next goes to VRAM or video ram.

    System ram is what the CPU uses to process object draws. Once the objects are in the GPU pipes system ram is irrelevant.

    IN fact that is one of AMD's stacked memory patents. AMD will be putting HBM on APU's to not only act as CPU cache but HBM video ram as well. They have patents for programmable HBM using FPGA's and reconfigurable cache memory HBM as well.

    Stacked memory HBM can also be on the cpu package as a replacement for system ram. Can you imagine how your system would fly with 8-16gb of HBM instead of system ram?
