this says nothing about the maximum OC headroom - can u not get into amd bashing right away? the i5 8400 has a baseclock of 2,8 ghz and everyone loves it, although in all honesty that 2.8 ghz baseclock is ridiculous - and its there for a reason.
and this ryzen is an engineering sample - the good thing is that apparently amd was able to increase clocks by 200mhz in the same tdp range, although the node was switched from "low power plus" to "leading performance" - i was afraid ryzen was going to lose its awesome efficiency around the baseclocks, but apparently this is not the case.
all in all this is very good news in the boundries of which we know for sure - better efficiency around "non oc" clock ranges.
now - lets put the big picture togehter - gigabyte offered a 6 phase vrm for ryzen on their highest end boards, which isnt that great. the new gigabyte board offers a properly doubled 5 phase vrm, ergo 10 phase, with a real heatsink + finstack.
if ryzen+ was going to hit a clockwall at 4,2 ghz paired with the better efficiency proven by this processor the 10 phase vcore vrm would be a HUGE waste, since at 4,2 ghz ryzen+ would pull roughly the same like ryzen 1 at 4.0 ghz - the gigabyte 6 phase is plenty sufficient for that.
the big question is: WHY then does gigabyte put a ridiculous 10 phase with real finstack-heatsinks on their board, which in fact makes it one of the most powerful desktop boards of all time?
this is likely because ryzen+ will put a huge strain on the vrm - and this en. sample is more efficient than ryzen, which translates into quite some OC headroom.
