How well will dolphin run on the m1 chip?

I'm sold, I've got an M1 Air coming in at the end of this month with the 8 core GPU (not that it will help too much).

IIRC running through Rosetta 2 knocks of 15-35% of performance depending on the application workload, so we could assume dolphin can squeeze out quite a bit more power with a native binary.
I think GPU performance is the same between native/Rosetta binaries.
