I'd be seriously impressed if one could get such monsters to 4.5 GHz on all cores using only water cooling.
EDIT:
@Gasaraki
I don't think EPS uses all wires for power. Bunch of them are probably grounding and signal, just like with PCIe power cables/connectors. Which means your formula doesn't quite work there...
First, the 7890XE boosts to 4.4 GHz on two cores, and 4.2 GHz on all the other cores. 4.5 GHz isn't much of a stretch, honestly. It's more about your board's VRM being able to handle the 350W+ power draw at those clocks on all cores. My 7980XE sample draws almost 285W at stock with boost enabled.
Also, EPS connector is 4x 12V, and 4x ground. PCIe power does have signal wiring, but not CPU EPS.
I'll have an article on these CPUs soon... waiting for new PSU, unfortunately.
