Use Quartz Debug for this purpose.

Does someone can help me to configure MSI Twin frozer and  Saphire Dual X 7950?

I am having correct test results with GL Wiev about 4100 points but Ocean  open CL is 85 points with reduced bandwidth.  Luxmark was about 2000 points but now it keeps crashing.

wWth booth cards it is worse and T am having random reboots.

 Thanks in advance.

@ gils83

 

you should have better results with your config + vsync=disabled

 

here's what I have with my old P5KPL-AM / E8400 / GTX 570  config

hello fantomas,

I already disabled V-Sync, the HD 7850 is an average card, the results of 570 compares with HD 69xx / 79xx, the results for the HD 7850 are consistent, it is a lowcoast model  860 Mhz / 1024 I should get to 480 FPS in Mavericks. the R9 270X (equivalent HD 7870) has a score of 550 fps

well... I believe you   :)

 

but it still is a bit strange, since both cards have pretty similar performance

Found interesting OpenCL (vs. CPU) Benchmark CompuBench CL - to have other OpenCL Benchtools beside this and Luxmark (2.0, 3.0 has major bugs in OS X).

http://compubench.com/result.jsp

 

Test select, default is CPU, check OpenCL (GPU) to measure GPU OpenCL

MY GT 440 (Nvidia) Results 

attachicon.gifBildschirmfoto 2015-04-07 um 13.08.46.jpg

hello ,

 

I do not think that this test reflects something serious, at least for AMD graphics card almost falling asleep (46 ° C max), it is optimized for Nvidia certainly and I had a fail test T-Rex and Bitcoin result is bad. Luxmark the test shows the true potential of OpenCL graphics cards.

 

When I see the final results of the different graphics cards, I still doubt, knowing that Titan X is less than in most of the areas facing an AMD 295 X

thanks :)

 

test in vidéo and music !   :D

You are not rigth, that the CompuBench CL is Nvidia optimized. Look for each test results and you find some test were AMD is faster than Nvidia!

Example the TV-L1 Bench: AMD 290 is much faster than Nvidia Titan there:  30 vs 20 in the result list. (Tab results in Compubench, TV-L1)

So i think , the bigger OpenCL test set of Compubench is serious because it runs not only one task and so shows results of more different gpu compute tasks than Luxmark.

Luxmark is good and serious but head dev has only AMD gpu to dev and test. Overall newer AMD have advantages over Nvdia (more by its better gpu compute hw design than drivers),but not in all OpenCL code conditions. Some conditions are better for AMDs advantages, like TV-L1 Bench others show not its adantages or even run faster on the Nvidia gpu hw design.

 

So its good to have    more than one OpenCL bench. If you compare all results its more real life than only one.

 

By the way, ist also interesting , in Compubench CL to see the diff between CPU and GPU tests. 

Last but not least: In all OpenCL benches, luxmark &.... , the CPU speed (GHz, cores, L1, L2 Cache size,..) does matter also for GPU OpenCL speed!

The faster the GPU the more the cpu speed does matter.

Because of the overhead transfering data + results to/from gpu to the cpu and OpenCL driver overhead.

Like OpenGL cpu+driver overhead heads into OpenGL speed diffs  for same GPU but different CPUs.

IMHO CompuBench is showing real world results
