Intel Haswell HD Graphics 4600 vs. AMD Radeon Graphics On Linux

As the Reaction Quake 3 game batters the R600 Gallium3D driver quite well, the Core i7 4770K on Intel's open-source driver beat out all of the AMD Radeon GPUs on their open-source driver but obviously came up short of the Catalyst performance.

By default the rendering of the R600 Gallium3D driver is incorrect for Unigine (without setting separate environment variables), but between the Intel Haswell graphics on their Mesa driver and Catalyst, the i7-4770K performance was about twice the speed of the Radeon HD 5450.
