OpenCL: AMDGPU-PRO vs. Crimson?

[zacdiggum]

Hi there,
could anyone with a dual-boot machine provide some benchmark results comparing OpenCL performance of AMDGPU-PRO and Crimson (on Windows)? I read the 'Blender is crazy slow' article but that's a Blender thing, right? Anyone doing GPGPU and could give his/her impression?

BMW benchmark, Blender 2.77, R7 Spectre CCN 1.1 GPU (A10-7870K)

GPU (OpenCL) render:

• Linux 4.7-rc6 + AMDGPU-PRO 16.30.3.306809 == 713 sec. (11:53 min)
• Windows 8.1 Pro + Crimson 16.3.2 == 573 sec. (9:33 min)

CPU render:

• Linux 4.7-rc6 == 602 sec. (10:02 min)
• Windows 8.1 Pro == 901 sec. (15:01 min)

GPU render is slower on Linux at this moment, but CPU render is much faster than on Windows.

16.3.2 is the latest windows 8.1 driver for APU.
