Very much. I did run a test yesterday in the german newsgroup dcoulh [1] with a simple testcase (including denoise and equalizer for heavy GPU-use) and the difference was huge: My old Phenom II 840 needs 68 seconds, a new and expensive i7 6700k still 36 seconds. The i7 with activated GTX1060 needs only 5 seconds. So: Forget the CPU, take a cheap one, the GPU matters. If someone wants to compare, take these two files: http://www.mirada.ch/bench.SRW http://www.mirada.ch/bench.SRW.xmp and then run: darktable-cli bench.SRW test.jpg --core -d perf -d opencl for testing the CPU only run: darktable-cli bench.SRW test.jpg --core --disable-opencl -d perf If you want to post your results here, maybe add: grep "model name" /proc/cpuinfo && free -h && lspci | grep "VGA" && uname -a I would be interested in the numbers of a RX460/70/80 with working openCL... regards Patrick [1]| https://groups.google.com/forum/#!topic/de.comp.os.unix.linux.hardware/K2mXwGyrdrM ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
