OpenCL - when to use it? (help and benchmark oppose each other!)
ektorbarajas:
Great!!!
Kind regards

Which would be better in this situation:
Work size= 64
CPU= 600ms
GPU= 74ms
Work size= 512
CPU= 700ms
GPU= 150ms
The 512 GPU is still much faster than CPU. So would 512 be faster than 64 in this case?
Admin:
lower values is better.
use work size 64, work size is how much separate "threads/processes" run simultaneously, it doesn't directly related to performance, different devices have different optimum value. 512 doesn't mean better 64.
