I couldn't find it in the thread (hope I didn't just overlook it), how does the speed of ECM on GPU generally compare to CPU? Say a GTX 1660 or similar.

And is it so that only small B1 values can be used? I found this paper and they also only seem to have used B1=50k. With a 2080 Ti they achieved "2781 ECM trials", I guess curves, per second for B1=50k. That is very fast, but if the B1 size is severely limited, a CPU is still required for larger factors?
