at least i remembered correctly.

edit: yeah i totally forgot. some people can't reach 24 FPS so they can't use dx9 <-> openCL for any realtime program. i call this a bug and i'm talking about GPU like r7 or r9 series.

Could you please relink that benchmark?

doesn't work with nvidia.

if i remember correctly someone has written a version for nvidia(was it cyberbeing? sorry i can't remember) but yeah this is the original version from madshi from his server for AMD GPUs (works fine for intel).

i use it with every new AMD driver version just to see nothing has changed...

[aufkrawall]

Thanks. Since I'm with NV, I hope that the author of the compatible version will read this or maybe someone else still has it.

It's a synthetic benchmark, so don't read too much into the result.

[huhn]

and it's a copy benchmark the really important part is the processing that's done on the frame later at openCL.

but numbers like 37 fps slow some real problem...

[Zachs]

I meant the Nvidia benchmark.

[aufkrawall]

With your benchmark 11, I'm getting 1278fps (GTX 980). Seems to be CPU limited. Cuda wrapper overhead?

[Zachs]

I think it's gpu memory bandwidth limited.

[huhn]

just run it with gpu-z.

[aufkrawall]

I get lower fps when I have Process Hacker opened, which consumes CPU power. But probably it could also be due to its way of GPU polling?
It's definitely bandwidth limited. When I OC VRAM from 3.6 to 4.0Ghz, I get an increase to 1380fps.

I get 164 fps for v11, AMD A6-5400K APU (HD 7540D). Haven't test on my laptop yet.

[Zachs]

Hi guys,

Thanks for all the help so far. I'd appreciate it if I could get you guys to run version 12 of the test app to see if it still runs and report back the new frame rate.

Thanks again!

Cheers.

Test version 12 on Optimus (Intel HD 4600 + nVidia 880M), 249 fps, with previous version 9, the fps was 366.

At the time, all I did compile a build with DirectCompute-only so I could see the results on my NVIDIA card. I never attempted to fix the OpenCL tests. It doesn't appear I ever shared the DirectCompute-only build back then, so here it is if anyone wanted it: https://www.mediafire.com/?u6x778w7odoaqdi

It is somewhat reassuring to see that NVIDIA has made some improvements to DirectCompute performance improvements since then though. A nice +65% increase (172fps->285fps) in DirectCompute Error Diffusion performance with 350.05 compared to the 321.10 driver I initially tested one year ago. Still quite poor compared to AMD cards though, considering even madshi's HD7770 could break 300fps in that DirectCompute test.

Version 12 gives 400-404 on my Optimus system.

Zach, you need to clear your inbox.

750 Ti 440 FPS build 12, we've dropped some performance.

[burfadel]

187.039 fps this time, AMD R9-280X.

[aufkrawall]

Gives me a performance gain with GTX 980, 1343fps.

On my GTX 560, it's gone up from 640 to 716fps. On the Intel, it's gone up from 315fps to 370fps.

*cough* 540 *cough*
