Intel HD 2500 Ivy Bridge Graphics On Linux
The four Intel Sandy/Ivy Bridge processors were tested in their stock configuration and then when the HD 2500/3000/4000 graphics were all tested when the CPUs were running at 3.2GHz, no Turbo Boost, and all four cores enabled without Hyper Threading -- to look more closely at the graphics performance by eliminating most of the major CPU differences.
This Intel Ivy Bridge Linux graphics testing is being done from Ubuntu 12.10 with the Linux 3.5 kernel and then pulling in the latest Git code of the xf86-video-intel, libdrm, and Mesa 8.1-devel components. First up are the Linux OpenGL benchmark results when the i5-2400S, i5-2500K, i5-3470, and i7-3770K processors were running in their stock configuration. The software stack and other components were maintained the same throughout testing.
OpenCL benchmarks couldn't be run in this article since the open-source Intel Linux graphics stack has yet to support OpenCL on the GPU.
