More Darktable GPU/CPU Benchmarks - 27 Different Setups

[finalzone]

Benchmark on ASUS X550ZE using Radeon R7 M265DX seen as Radeon R6 and running on Wayland session:

Thank you Michael for all the testing, i think darktable and opencl deserve this attention.
if you want to burn you cards in a heavier test: You could take a BIG raw like one from Hasselblad medium format:

http://www.rawsamples.ch/raws/hasselblad/h3d-39ii/RAW_HASSELBLAD_H3D39II.3FR

and then apply my xmp-file with this raw. Maybe the ranking is the same, maybe not. Looks like it takes 6 times longer than the raw from my Samsung on a GTX 1060. Which is a lot.

Finally let's hope that we get soon some numbers with the open source drivers.....

Michael this!

Any idea why a i5-6500 is nearly twice as fast as a i5-6600k?

Also GTX 980Ti being 10x faster than a GTX 980? Obviously can these numbers not be used in any meaningful way outside this particular test and setup, making the benchmark about as remarkable as a doorstop on a motorway.

A little less numbers and more factual reporting would have made it a much better article.

It would be helpful to post the full output of darktable-cli. Then we could see the needed time of CPU and GPU for _every_ module. The big difference between the two i5 are only possible at either denoise or equalizer module (or both together). No idea about testcase 2 and 3, because i don't know which modules are used there.

Very interesting, thank you!
About the Intel HD problem: for some reason it is also necessary to install intel-opencl in addition to beignet to make the intel integrated graphics work (7th gen).
Here some results on my t470s with 7500U (ntel HD620):

The integrated graphic is about 1/3 faster than cpu only. Still to slow to use darktable regulary.
