AMD Radeon R9 Fury reviews

Civilization: Beyond Earth used it for a cleaner take on split frame rendering for multi-GPU setups. It doesn't really help the framerates, but it keeps the latency down.

There won't be any more of a line with DX12/Vulkan than there was with DX11/OpenGL. Developers are still going to find new and exciting ways to hang themselves, and driver teams are still going to work on game specific optimizations since it's in their best interest to deliver the best possible performance for their customers.

 

Well then, enlighten us!

 

I don't believe it's defined as TrueAudio has in the PC space. There are specialized resources with many shared hardware traits to the PC blocks, and the console platforms utilize them for their needs.
However they tweaked them, how the IP is exposed, or all the use cases are not openly discussed as TrueAudio has been.

Relative to DX11, Mantle exposed the existence of the specialized queues like DMA and compute. The actual engines for them would have been abstracted or not utilized. Asynchronous compute apparently runs into the hard ordering limits of DX11.
Indirect operations and GPU-side occlusion queries were documented in the Mantle guide.
DX12 changes things, but its revealing them to the world at large has a chronological disadvantage.

 

But the draw back in the exposure and giving more control to the developer is more things can go wrong, and drivers might have to be tweaked more so then before. All depending on the API programming rules.

This has always been the case of low level programming, and the reason why high level programming was introduced. I am not saying its a bad thing, I think its good that the programmer has this type of control but because of the two different IHV's programmers might have affinity to a programming style that is better for one of them. Which actually is there right now too when shaders are concerned.

 

Indeed, watching some of the AMD fans celebrate it as removing nvidia advantage with regards to earlier driver optimizations due to closer developer relations, it very amusing.

 

Apparently the disabled shaders can be partially unlocked on Fury cards. Complete unlocking is a no-go since some of the shaders are defective and artifacts result.

What's SE symmetry?

 

Fiji has 4 Shader Engines and they should have the same number of enabled shaders or the slowest will limit the performance of the others.

Asus R9 Fury Strix (unlocked to Fury X) achieves 40%(45% non-unlocked) core & 100% memory overclock, using LN2 extreme cooling and physical voltage mods.
48% higher 3DMark Fire Strike Extreme result.

Impressive OC on the ram.. 500>1000mhz and so this mean 1024GB/s of bandwith.

 

What is the life expectancy of these being highly overvolted and overclocked?

 

Probably not much, but likely more than the uptime permitted by the capacity of the LN2 tank.

 

Voltage was bumped from 1.35V to 1.55V for HBM which considering LN2 cooling shouldn't be a problem even after several runs. I would be more concerned with effects of cooling stacked dies and heating them up again. It's a bit of uncharted territory with first signs being very promising for extreme cooling applications for HBM. I was worried memory would just cold bug below certain temperatures.

Wonder what you could do with that 1TB/s memory if not for other architectural bottlenecks in Fiji!

 

Maybe the overclocker's dream was meant for LN2...
Pretty insane how people mod the cards to OC in LN2 tho.

 

Interesting, but 40-45% core bump on LN2 is still pretty disappointing IMO - especially when GM 204 / GM 200 are approaching a 100% core OC under the same cooling (BTW: that 3DM 10K score is almost as high as the best GTX 980 result). Granted, the GPU+HBM package in all likelihood makes overclocking trickier, but the LN2 results seem of more academic interest since I doubt the Fury/Fury X will be grabbing any world record headline marketing gold (I'd assume that the OC-friendly 980 Ti (Kingpin, Lightning, Matrix Platinum, HOF LN2) results will continue to rise as competition heats up.
