"Last week I posted some AMD proprietary vs. open-source AMD Linux driver benchmarks using the very latest code. Left out of that earlier comparison was the R9 Fury series with Fiji GPU as well as newer graphics cards using the Tonga GPU. These graphics cards are supported by the AMDGPU DRM driver rather than the long-standing Radeon DRM driver. As I've been mentioning a lot this week, Linux 4.5 will bring the PowerPlay power management / re-clocking support to AMDGPU. In this article are showing benchmarks of the Fiji and Tonga GPUs under Linux 4.4 and Linux 4.5 DRM-Next along with the Catalyst 15.9 driver as shipped by Ubuntu 15.10."
