20-Way NVIDIA/AMD GPU Darktable OpenCL Photography Performance

@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.

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!

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

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

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

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.

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

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.
