How many work items A10-7850A's GPU runs the fastest

Goal to the faster calculation, I try to change

clEnqueueNDRangeKernel API's parameter "*local_work_size".


I think the more "local_work_size" the faster processing.

But actually processing speed is saturated at

  local_work_size = 8 to 16,

gradually slowdon more than local_work_size =  20.

I think it strange because A10-7850A has 512 stream processors.

What wrong?
