Can't test mining when dev don't have the cards to update their mining softwares. It's RDNA, not CGN anymore.
Understandable...but i'd expect at some level openCL hardware abstraction would be able to hide
hardware and do it in unoptimized way...maybe those 4MH/s someone mentioned are
measured that way, but sounds way too slow
Based on reviews though the OpenCL compiler seems to have major issues so that could be part of the problem. (they probably did it on purpose to keep miners at bay until gamers buy them
