I can't seem to find this info anywhere. It would be logical that the blockchain driver defaults to the compute mode and not even be any option anymore. But after quite a few iterations it seems that my RX580 8GB card has hit a limit that is more than 30% below all reported performances.
MSI Armor RX580 8GB OC
BIOS memory strap
Memory OC
Max hash rate 23MH/s
reported max hash rate 30MH/s (with exactly the same setup)
Anyone with experience of info is greatly appreciated.
