Phoronix posted a comparison review of the AMD Catalyst drivers on Ubuntu 12.10 and Windows 7
For those wondering about the performance of Ubuntu Linux 12.10 versus Microsoft Windows 7 when using the same system and the Catalyst graphics driver, here are new Phoronix benchmarks of an AMD Radeon HD 6870 graphics card when running a variety of OpenGL workloads from Ubuntu 12.10, Kubuntu 12.10 (the KDE desktop version of Ubuntu 12.10 to avoid the Unity desktop overhead), and Microsoft Windows 7 Professional x64.AMD Catalyst: Ubuntu 12.10 vs. Windows 7
Back in September I delivered new OpenGL Linux vs. Windows performance benchmarks when using Intel graphics and then a NVIDIA graphics comparison with multiple graphics cards. In this article are the AMD Catalyst results from the competing operating systems. This time around a Radeon HD 6870 graphics card was used for testing, but due to problems between the packaged fglrx driver and the Unity desktop, only this graphics card was tested and not a range of graphics cards as done in previous multi-OS comparisons.
