BioShock Infinite was a few frames faster on the tested graphics cards when using the AMDGPU DRM driver over the default Radeon DRM.

The HD 7950 was faster on AMDGPU with Deus Ex: Mankind Divided while the R9 270X and R7 370 GCN 1.0 hardware was unchanged.

While Dota 2 was slightly faster switching over to AMDGPU.

The Dawn of War III OpenGL performance was roughly the same on these Southern Islands GPUs.
