Under Windows 10 Pro x64, the Radeon Software Crimson Edition 16.6.1 driver was used for benchmarking. Under an updated Ubuntu 16.04 stack, tested first was the AMDGPU-PRO Beta 2 (16.20.3) driver. After testing this hybrid driver, the Linux 4.7 Git kernel was installed along with Mesa 12.1-dev and LLVM 3.9 SVN via the Padoka PPA for providing a very bleeding-edge look at the open-source AMD/Radeon Linux graphics driver performance.
