AMD Radeon R9 285 Tonga Performance On Linux

Thanks to Xonotic running well on the Catalyst Linux driver, when looking at the performance-per-Watt of the AMD Rx 200 series GPUs they come out ahead of the GTX 760 and even the GTX 780 Ti.

The performance-per-Watt of the LuxMark OpenCL workload was also good for the Radeon GPUs given the good Catalyst driver GPGPU performance with these GCN GPUs.
