OpenCL Oceanwave Bench and (new) CompuBench CL

374 posts in this topic

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).

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

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.

As we see, Windows is much faster. :(

I've been away for a while, but as OCL bench whore I couldn't resist Compubench :D, so here I am.

 

Sadly it doesn't support multiple cards, so I can only post single R9 280X (crappy MSI one BTW) result.

Only one test, which does work with more than one card (T-Rex) fails on 280X, at least on 10.10.3.

Mac Pro 4,1 firmware updated to 5,1 with a Gigabyte R9 280x v3 with resistor R17 modification and flashed with EFI. Underclocked to 1000Mhz and power limited to 225W to match maximum Mac Pro power supply.
