[Split] PowerSpectrum Unit Test

<< < (58/62) > >>

Jason G:
Cheers,
  BTW: average roughly represents overall improvement, Peak represents speed change in the fastest Kernels, and Min is the speed change in the slowest Kernels ... So I regard 'Avg' & 'Min' as most important, with Peak being mostly just a possible indicator of remaining headroom.

[Edit:] Similarish looking deal with the 480
