Come on Apple, improve your 3d drivers

October 27th 2015 Posted to Apple,ATI

Few tests with same config (R9 290x, MP3,1, 2×2.8 GHZ cpu) in Unigine Valley. I know this cpu sucks for valley, but it’s enough to compare different OS/drivers.

OSX 10.11.1
OSX

And opensource driver is getting very close to OSX, that’s very surprising
Ubuntu 15.10 + Mesa 11.0.4 (opensource driver for radeon)
Linux_Gallium

Both are far from windows tho.
Windows OpenGL
Windows_OGL

In case of 3840×2160 and noAA the scores are:

OSX: 840
Linux: 709
Windows: 950

A bit better story for Radeon.

    I’ve seen other Unigine comparisons that put OS X very close or faster than Windows. Usually on a different GPU or OS version than what’s used here. The 290X is not sold in any Mac, and the 3.1 Mac Pros have issues with power management on certain GCN cards. I doubt that explains the results though.

    Wow.

    Got a score of 1313 with a 3.33Ghz 6-core mac Pro on 10.10.5 and a radeon 7970. Maybe your processor is not fast enough for the video card, or apple gpu driver are badly optimized for the 290x

    With a slow CPU performance is constrained by driver optimisation. With a fast CPU, performance is more limited by the GPU hardware. So differences between OS X and Windows start to decrease at very high resolution or with a slow GPU and/or fast CPU.

    Glad I am not the only one that saw El Capitan Unigine (and Cinebench) graphics benchmarks tank in comparison to Yosemite. Even in gaining I am getting stuttering.

    System: Z77X-UD5H, i7 3770K, 2x HD7950 3GB
