Nearly at 4,5 Ghz on the Ryzen 9

Benchmarked it with SciMark for Single and FFTE for Multithread max frequencies. In lack of the k10temp, I have choosen the fan speed as a measurement. Highest temperature of 80° would be 3600 rpm:

So far those CPUs seem to perform very well on Linux. The temps are way lower than on my R7 2700X, its stable idling at 40° and I can get easily in the 4,5 Ghz range on liquorix kernel. So with new Agesa drivers the 4,6 ghz comes closer .

In the test nothing is OC'ed, except for the RAM @ 3200 Mhz.

I found this quite interesting article on reddit, I don't know what's the case with Zen 2 but this guy (an experienced overclocker from hwbot) measured what are the temps and voltages where Zen+ starts to see some degradation.

Apparently, in the case of Zen+, if the max temp goes above 58ª C (under common load), and the voltage above 1.375 then your CPU is going to degrade a lot faster.
