Plot3D and Furmark also saw big boosts in performance for the Radeon HD 7950.

More wins with the triangle test except for the Radeon R9 290 still in a broken state.

From this initial testing of drm-next-4.7, the Radeon DRM driver is looking to be in good shape except for a significant regression affecting the Radeon R9 290 and then also BioShock Infinite and DiRT Showdown breaking on this setup. The R9 290 saw its performance fall significantly compared to Linux 4.6, but with this only being the drm-next period and the Linux 4.7 merge window not even being open yet, it should get addressed in time for Linux 4.7. For the other three graphics cards, their performance was either the same or higher with Linux 4.7. With several of the tests, the HD 6950 / HD 7950 / R7 370 saw significantly better performance under this newer kernel code.

Stay tuned for the AMDGPU tests tomorrow with Tonga and Fiji.
