i mean with full speed on. 2700x does 4.35 so its not that much extra is it ? so to expect 4.5 stock no i think that is more than expected from this revision of cpus.
Of course it is, you forget its not just about if its stable, but also if it can run at those clocks all core whilst within TDP limits.
4.5 is a massive jump.
Do you expect zen2 to be able to do 4.5 at below 1.2 vcore?
