Pre test new Benchmark for Blender 2.79

Support Technical Support

Hi, YAFU and me prepare a new benchmark for Blender 2.79 but we don´t have AMD GPU to test.
We need help from AMD user to get the best tile setting and if all is OK with the file for OpenCL kernel.
The file is prepared for NVIDIA so big tiles.
I spoke with the split kernel developer Hristo Gueorguiev (nirved) and he told me 64x64 is now best setting for AMD.
Please test the file and report render time and your GPU, OS is fine to but not needed.
I will add image how it look.
It is important to use official buildbot, most additions for OpenCL are not in 2.78.

File was created from YAFU with small changes from me.

Cheers, mib

AMD r9 390x 8GB

Loading render kernels time: 01m29s

These renders are without the kernel calculation time.

64x64:04m27s

One big tile: 03m33s

Hi bigbad, thanks for testing.
I wait another 2-3 user results then I talk with Nirved again about 64x64. :wink:

Cheers, mib

ubuntu 16.04
amdgpu-pro 17.10
R9 290
tile 256x256
04:36.79

This particular file likes bigger tiles, so we should use something like 256x256.

BTW principled slows down current split kernel, f980e859 (just before principled): 03:26.83

I am very grateful because a few months ago AMD gave me a FirePro W9100 32GB but it does not work well in Blender for now.
I hope I can help you.
