    strange, why should darktable care about the type of GPU? As far as I know, darktable tests whether the GPU has enough memory and whether it is fast enough. Based on that it may disable OpenCL support. I have an old Intel HD 4000, which is slower than the CPU

    Nice.
    Perhaps once Gimp 2.10 is ready could be made another OpenCL test for it.

    It is unfair, because 'better' is very relative:
    - For some 'better' means faster, no matter the cost
    - For others, it means bang for buck
    - For others, Open Source drivers...

    It all depends on what you're looking for...

    Thanks for including only the CPU results. Makes the graphs much more interesting.

    I think the main thing one cay say for sure is that OpenCL is pretty much a second-class citizen for Nvidia, they prioritize CUDA much more (in terms of performance, tooling, etc).

    No, they are HEAVELY multithreaded. Lots of CPUs take more than a minute for the "boat" test.
    Ok, maybe Michael could edit the article to mention this? Along with the number of threads used.

    Time to release the OpenCL code AMD?Just yesterday we were talking about how useless is the FOSS driver in that regard.
