Does Mountain Lion do graphics faster?

Originally posted Friday, July 27th, 2012, by rob-ART morgan, mad scientist

We, like many of you, wanted to know if graphics intensive apps run faster or slower after upgrading from OS X Lion to Mountain Lion. To help answer that question, we chose to test three GPUs using seven graphics intensive tasks.

Retina MacBook Pro =
'mid 2012' Retina MacBook Pro 2.7GHz, NVIDIA GeForce GT 650M GPU

MP Radeon HD 5870 = 'mid 2010' Mac Pro 3.33GHz Hex-Core, AMD Radeon HD 5870 GPU

INSIGHTS
The gain or loss in graphics processing speed when upgrading to OS X Mountain Lion depends on what GPU you have and what apps you run. Some app functions run faster. Some run slower.

One notable gain by the Retina MacBook Pro's GeForce GT 650M was the Heaven 3.0 OpenGL Benchmark. Notable losses in speed included Dirt 2 hi-rez, Photoshop CS6 Liquify, and Motion 5 RAM Preview.

The Mac Pro with the Radeon HD 5870 gained speed running Photoshop CS6's OpenCL effects and Motion 5's RAM Preview. It lost ground running Premiere Pro CS6's Fast Color Correction and all but one 3D OpenGL scenario. The Mac Pro with the GeForce GTX 285 had signficant speed lost rendering the Premiere Pro CS6 and Photoshop effects we chose.
