I did some testing on the best tiles size for rendering with cycles in blender 2.8. I thought I would share my findings to help others to optimize their renders.

Thank you. Excellent information.
2.8 and 2.79 definitely have inverse performance relationship to tile size..
If it is to remain this way this ought to be communicated to users.
Thank you for this "Cycles tile size in blender 2.8" Article it highlights a very important issue.
I was curious, so ran some tests:
980ti
- 512 x 512: 3:32.07, 3:27.98, 3:28.58, 3:28.59
threadripper 1950x
-32 x 32 3:40.43, 3:37.69, 3:27.44, 3:34.30, 3:39.22, 3:35.86, 3:37.06, 3:38.85, 3:35.22, 3:36.28, 3:35.46
-64 x 64 3:39.01, 3:34.61, 3:33.08, 3:34.83, 3:33.27, 3:32.45, 3:33.89, 3:34.80, 3:32.60, 3:35.44, 3:36.85
I'm wondering now if I misread the time for the 32x32, although I did check; it seems odd.
I would suggest, anyone with a higher core CPU to not presume 16 or 32 is the best; 64x64 slightly edges the 32x32.
