zoltanpl Posted March 18, 2015 Share Posted March 18, 2015 Hi I'm new here. Thanks for your hard work on AMD dev. Few question about performance AMD machine. My spec is: FX 8120@4.125 fsb 250 Asus m5a99x evo SSD + few HDD and most important 2x GTX 680 (EVGA 4GB) PCIe: x8 on both problems with FSB reading but no impact to work. Now i'm using Yosemity 10.10.1 (from yosemite zone). I'm a little bit noob about advanced configuration but i'm able to change required kext and change kernel. Earlier i was using maverick. Performance problems exists in maverick and yosemite (equally same). I change kernels, IO kext and no luck. 1) performance of opengl is around half of performance on Windows (Cinema benchmark) 2) CUDA work very well on both gpu (Blender) - simillar or a little bit better than Windows 3) Most important for me - Apple Motion - Ram preview stuck around 12-14 fps on HD video(but if i remove physically secondary GPU) works ok. 4) After Effects - oh there are strange things - when playing from ram preview there are few things if i change view in active camera to 100% drop to 11fps, 50% 15-16 fps; 1,5% realtime preview 14fps - it's strange becouse secondary display (mercury preview) display full HD size with full speed (of course if active view is resized to 1,5%) Please Help Chrome is also slow in Yosemite in maverick Work ok. ahh and playing full HD video by QT or other soft works also ok, even 60 fps.

gils83 Posted March 18, 2015 Share Posted March 18, 2015 hello , cinebench opengl does not reflect the truth of the potential of said graphics card, test to be performed with Geek3D OS X and compare the results with those of windows http://www.geeks3d.com/20140304/gputest-0-7-0-opengl-benchmark-win-linux-osx-new-fp64-opengl-4-test-and-online-gpu-database/#download Link to comment Share on other sites More sharing options...
