Phoronix has published a 15-way Open-Source Intel/AMD/NVIDIA GPU Comparison
When running Fedora 19 with its updated open-source Linux graphics drivers, 15 different Intel, AMD Radeon, and NVIDIA GeForce GPUs were compared when looking at the open-source Linux OpenGL performance. The tested graphics processors span from the Intel HD Graphics 4600 "Haswell" integrated graphics to the AMD Radeon HD 7950 "Southern Islands" graphics card to the vintage Radeon X1800XL.15-Way Open-Source Intel/AMD/NVIDIA GPU Comparison
With the stock Fedora 19 KDE RC2 installation, which provides the Linux 3.9 kernel, Mesa 9.2-devel, and the latest X.Org DDX drivers, the 15 different graphics configurations were benchmarked in their stock configurations and settings. All OpenGL benchmarking was handled via the Phoronix Test Suite.
