AMDGPU-PRO Beta 2 vs. Mesa 11.3 + Linux 4.6: Very Competitive For Linux Gamers

Following last week's AMDGPU-PRO 16.20.3 "Beta 2" driver release of AMD's new hybrid driver stack for Linux that makes use of the AMDGPU open-source kernel DRM driver with the closed-source OpenGL driver derived from Catalyst / Radeon Software, I set out to do a fresh open vs. closed-source driver comparison. For the Radeon R9 285, R9 290, and R9 Fury, I compared the performance of this new AMDGPU-PRO driver against Mesa 11.3-devel Git and Linux 4.6 for the latest open-source driver stack.

Intel's P-State Driver Does Seem To Be In Bad Shape On Linux 4.6~4.7

A few days ago when delivering benchmarks of the new CPUFreq "Schedutil" governor in Linux 4.7 the P-State comparison results on this Git kernel looked particularly terrible. I've since done some P-State tests on the same system using the Linux 4.5 and 4.6 kernels that further point towards a regression having taken place.

Linux 4.7 CPUFreq Schedutil Testing vs. P-State

With the in-development Linux 4.7 kernel there is a new CPUFreq governor that leverages the kernel's scheduler utilization data in an attempt to make better decisions about adjusting the CPU's frequency / performance state. Here are some benchmarks of that new CPUFreq governor, Schedutil, compared to the other CPUFreq governors as well as the Intel P-State CPU frequency scaling driver.

Intel Is Getting Very Close With Its Last Extension For OpenGL 4.3

For Broadwell hardware and newer, this week marked the milestone of the Intel Mesa driver exposing OpenGL 4.2 support. However, they are only one extension away from OpenGL 4.3 compliance for the newer Intel graphics hardware and a new version of that patch-set was just posted.
