15-Way Open vs. Closed Source NVIDIA/AMD Linux GPU Comparison
All of this benchmarking for the two earlier articles happened from and AMD FX-8350 "Vishera" system so unfortunately there are no Intel Linux OpenGL performance results to share within this article. Benchmarking happened on Ubuntu 13.04 with the Linux 3.9 kernel and Xfce 4.10 desktop.
All benchmarking was handled in a fully automated and streamlined manner using the open-source Phoronix Test Suite framework.
