Retina MacBook Pro Graphics: OS X Is Okay, But Linux Breaks
Posted by Michael Larabel on August 08, 2012
While the Apple MacBook Pro with Retina Display is beautiful having a 15-inch display running at a resolution of 2880 x 1800 and 220 pixels-per-inch, Linux isn't ready for this high-performance, high pixel density notebook.
Details in full for running Linux on the Retina MacBook Pro will be published in the coming days along with benchmarks, but simply put, Linux isn't ready for this new high-end Apple notebook that's based upon Intel's Ivy Bridge processor with hybrid NVIDIA graphics and a retina display. Linux fails miserably at this point on the hardware for Linux desktop end-users, aside from the troubles with using an Apple Thunderbolt Display. This article will be along the lines of Linux Fails With The Apple Retina MacBook Pro.
The Linux desktop isn't properly ready for this high pixel density, Thunderbolt has the aforementioned problems, hybrid/switching graphics aren't yet properly supported under Linux, there's even simple mode-setting issues with this hardware, the battery power consumption is a disaster with Linux compared to OS X, etc. All the details will be revealed in this later article; I'm just waiting for the next round of August advertisements to get going, in order to support this extensive testing work and hardware purchases that were involved with this much sought after Linux hardware testing.

Anyhow, for those curious about what the retina display 2880 x 1800 graphics performance is like when the GPU drivers are working, here's some results under OS X 10.7 and OS X 10.8. As shared a few days ago though, Linux Isn't Alone With OpenGL Driver Issues.
Benchmarks were done of OS X 10.7.4 and OS X 10.8 from the 2012 Retina MacBook Pro with 2.3GHz Ivy Bridge CPU. These are just some random benchmarks to show what the OpenGL frame-rates are like for Apple's operating system when running at the impressive 2880 x 1800 graphics and using the auto-switching Intel HD 4000 / NVIDIA GeForce GT 650M graphics support.
Xonotic fairs pretty well at the 2880 x 1800 resolution even as the image quality settings are increased. OS X 10.8 "Mountain Lion" does appear to offer up some OpenGL performance improvements for this hardware configuration over OS X Lion. If you want to see how your system compares to these Xonotic results, with the Phoronix Test Suite installed it's just a matter of running phoronix-test-suite benchmark 1207314-SU-1207300SU41.
More data is forthcoming.
