Intel HD 2000/2500/3000/4000 Linux OpenGL Comparison

Starting with Doom 3 at 1920 x 1080, the results are to not much surprise. The biggest leap in performance comes with the Core i7 3770K. Besides having the HD 4000 graphics, the i7-3770K is clocked slightly above the i5-2500K CPU with its HD 3000 graphics. With the HD 4000 graphics, however, the Doom 3 frame-rate was still below 60 FPS.

With the Quake 4 game, at least the Core i7 3770K "Ivy Bridge" is nearly at 60 FPS. It will be interesting to see how Haswell performs once the processors are officially unveiled.

Ivy Bridge does much better than Sandy Bridge at handling the Unigine Engine on Mesa 9.2. The Core i5 2400S (HD 2000) graphics were sub-1FPS and so were the HD 3000 graphics. The Core i5 2500K was running, but with sub-1 frames per second and needing to meet deadlines, the Unigine tests on that CPU were ended prematurely. With Core i7 3770K with HD 4000 graphics on Mesa 9.2 / Linux 3.10 was only putting out 12 FPS at 1920 x 1080.

If lowering the resolution to 1024 x 768, the HD 4000 graphics frame-rate nearly doubled.
