any chance you will begin to work on nvidia and cuda? amd is reaching is limit already i don't think it's possible to do high improvement anymore
on the other hand a 1070 is stuggling to have 125 sol and it should be 160 at the very least, and i think it might be higher, up to 180...
I still can improve speed, though it requires more and more efforts and time. It seems about 300H/s on stock 390X is possible. So it's not over for AMD yet and therefore I don't have time for NVidia.
I am curios why older cards perform better then new ones..my 280x have more hash then my rx 470 and rx 480 even 470 and 480 should have more horse power
