    Phoronix: 20-Way NVIDIA/AMD GPU Darktable OpenCL Photography Performance

    With the holiday season in full swing, whether you are just a casual photographer or professional, Darktable is easily one of the best photography workflow applications and it's free software! Darktable has offered OpenCL acceleration for providing faster performance on GPUs and with the imminent Darktable 2.2 release there is even better OpenCL results. For those curious about the OpenCL performance of Darktable, I've done some Darktable 2.2-RC1 benchmarks on a variety of NVIDIA GeForce and AMD Radeon graphics cards under Ubuntu Linux.

    I love darktable, though i wish the ui was as simple as lightroom. definitely powerful though

      i doubt that nvidia has a problem with opencl. They simply don't what that the beginner and middle class cards perform well with opencl.

        Cool! I like this test suite and hope to see more of it - Well done Michael !

          Really nice test. Hopefully soon we will be able to see OpenCL tests with the open AMD driver.

            Very interesting results. It's great to see AMD cards performing that well.

              That increases my longing for an OpenCL implementation in the free stack. Or a more modern AMD GPU. I use Darktable quite often and this benchmark really shows the possibilities of OpenCL for certain tasks.
              Very interesting test!
              Stop TCPA, stupid software patents and corrupt politicians!

                @Michael: Are the CPU tests single-threaded? I couldn't find this information in the article (or maybe I just missed it)

                  No, they are HEAVELY multithreaded. Lots of CPUs take more than a minute for the "boat" test.

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