AMD Radeon R9 285 Tonga Performance On Linux

A variety of OpenGL and OpenCL Linux benchmarks were carried out on all of these GPUs from the Core i7 5960X system while running Ubuntu 14.04 LTS with the Linux 3.15 kernel and with fglrx 14.30.4 and NVIDIA's 343.22 binary driver. All benchmarks were done in an automated and fully repeatable fashion with the Phoronix Test Suite. Following the raw OpenGL/OpenCL results are some performance-per-Watt, power consumption, and thermal numbers.
