While for the most part the Catalyst driver performance for the Radeon HD 7950 graphics card was close between Windows 7 and Ubuntu 12.04 LTS, there were some OpenGL performance differences. The performance should largely be the same since the Catalyst code-base is mostly shared across AMD’s supported operating systems with the driver weighing in at millions of lines of code. However, there were some differences, including when the NVIDIA Linux driver would be faster than its Windows counterpart, the AMD Catalyst Linux driver would struggle in comparison. At the end of the day though, the differences are not likely to make or break your decision in choosing between Windows and Linux when using the company’s proprietary graphics drivers.
