AMDGPU vs. Radeon GCN 1.0/1.1 Benchmarks With Linux 4.10

With the Linux 4.10 kernel there remains experimental Kconfig switches for being able to build the Linux kernel with GCN 1.0 "Southern Islands" and GCN 1.1 "Sea Islands" support in the newer AMDGPU DRM driver rather than the mature Radeon DRM driver. For your viewing pleasure today are benchmarks of a few GCN 1.0/1.1 GPUs when testing the Linux 4.10 Git kernel with Radeon DRM and then the experimental AMDGPU DRM driver while both kernel drivers were tested in conjunction with the same Mesa 13.1-dev snapshot as of this week.
