Comparing that to the Z270 Xpower Gaming Titanium gives some interesting perspective on Ryzen's OC potential.
This is all pure speculation, of course. But:
-We know the average 7700K
might reach 5GHz. But most likely the "6" step is as far as it will go with an automatic OC. The "4" step should work for most chips. The same goes for the 6700K - more than 4.7GHz is a stretch, while 4.6 isn't uncommon.
-Given that MSI is trying to make things equal across their boards, that should give stable auto OCs in the ~4.2 GHz range. And I take this to mean for all cores, of course.
I'd be
more than happy with that.
