Nice. Do you mind doing a benchmark spanning every FFT? It might give us an idea of how infinity cache scales. If you can run bash scripts with WSL then this might do the trick executed from the...

Awesome, so gpuowl has been greatly optimised in the past year as I thought. It does yield an interesting data point, the 6900XT has ~84% the throughput at 79M but only ~66% the throughput at 332M....

If we're bandwidth limited there's a chance it might scale down better than that, although binning will pull it back the other way and probably then some.
