post #51 of 203
even if half of what's nvidia claiming is true..i should see significant improvements on my old Q6600 + GTX460

Wow. If they can really deliver on those claims...

Looks like we're getting a taste of DX12 a lot sooner than expected. I guess X-mas 2015 is coming early, eh?

Thanks Nvidia! thumb.gif

I tested a bunch of different reps with vishera FX (not sure if 8320 or 8350) @4ghz and 4.5ghz against my Haswell@4.5 and from that and previous observations i can be pretty sure that the difference between a phenom II @3.7ghz and Haswell @4.5ghz would be way, way more than +50% in sc2. Matching clocks, Vishera can't hope to compete in an engine that's extremely reliant on a single thread (to the point of sub-30% load on a quad core in a big fight when choking) that responds to memory and cache performance, nobody expects it to come close - it's a worst case scenario for the architecture

Considering SC2 is using 2 Core i can easily see 2 full Haswell core being 50% faster then 2 FX core.

More like 1.2 - 1.5 with a fast cpu

This is bad for linux frown.gif

If Mantle gets pwned, the only hope for a multi platform API will be lost. (not looking at you, Mr OpenGL)

That means no killer games for Linux. frown.gif
post #56 of 203
Signs that this is all about pr rep talk, considering true;
-Nvidia is suddenly playing nice with customers, extending compatibility of previous generation gpus to future features. Doubtful.
-Nvidia is not gaining any advantage from this efficiency trend while the most of the enhancement is for the lower spectrum of cpus, contrary to its brand positioning. Defaults on current knowledge already.
-If successful, AMD would actually benefit more: Atomic operations allow AMD to inherit multiarray approach that is faster on AMD hardware. Gtx 680 cannot use this path, the fastest is "persistent mapped". Notice, Nvidia has stated that the uav functions that defaulted their 11.1 support status do not relate to their 3D performance in any way. I find that hilarious.
GDC 2014 - OpenGL Conference
Just take a look at the slides 34 and 66 please. Clearly, Nvidia does not support building data structures on the gpu as the "fastest" approach, as persistent mapped relies on the cpu to do the job. Ergo, I safely claim that Nvidia's achievement will never be as efficient as AMD's. Haha, Nvidia.biggrin.gif I have got you this time.

Why are you dismissing OpenGL? It's the poster-child for cross-platform graphics APIs. Mantle was never going to become the primary graphics API on Linux.

its not all about pure performance at the very top end. the majority of gamers arent in that demographic. They key to openGL's success is in being a cross platform API meaning Linux, Mac, Windows, ,xbox360, Xbox-one,PS3,PS4 etc.. anything that supports OpenGL (which is everything) can get a port and the management team can satisfy their shareholders.

OpenGL needs better programmer support if it ever hopes to be taken seriously again.

We will find out how it actually plays out soon enough. Contrary to some people, iv'e been getting better & better performance with my tri-sli+surround with recent nvidia driver updates.
