Open-Source Linux Graphics: A10-7870K Godavari vs. i7-4790K Haswell vs. i7-5775C Broadwell

To no surprise, the Core i7 5775C with the Iris Pro 6200 graphics that boast eDRAM blow the A10-7870K Kaveri graphics and Haswell HD Graphics 4600 out of the water. The i7-5775C was 70% faster than the i7-4790K and 2.15x the A10-7870K.

The peak frame time for the i7-5775C with OpenArena on its highest settings was also much better than the Haswell and Godavari/Kaveri systems.

With the SuperTuxKart racing game, the Broadwell Iris system running Fedora 22 with the open-source drivers continued dominating Haswell and Godavari.

Tesseract is one of the more visually demanding open-source game engines and here the i7-5775C performance was double that of the Intel i7-4790K and AMD A10-7870K.
