Core i7's static PMOS is quite voltage tolerant too, just that it didn't matter that much probably because the uncore section is a powerhog anyway.
Lostcircuits measured it I think and got 44W for the uncore alone.
I read their i7 Power Plays article.The article is quite an eye opener since they concluded that total chip power draw is near 204W(that's including uncore part).205W-210 for a stock 965EE with turned-off over-current protection is a lot,and there needs to be a change how review sites measure power draw from now on,since methods used up until now can't be applied to core i7 anymore since "the entire Uncore is uncoupled from the CPU’s main power supply coming in through the auxiliary 12V rail".

They didnt measure anything. They took max values and made a dumb conclusion from that. Its abit like saying a 230V/10A outlet always pumps out 2300W nomatter what you plug in.

Crunching for Comrades and the Common good of the People.
indeed, they even mention in there articel themself, that intel said no commercial available software is able to utilize all parts of the cpu at once, so that 210W figure is just a (fictive) worse case.
It would be the same if they would use the AMD Max power specs.
I/O is rated at ~7W, NB somewhere around 23W and the highest IDDmax i have seen is 106A, but amd reated every TDP segemt on its own, intel on the other hand only lists the max possible for the whole family.
So if you take the worse cases:
30W uncore part
106A*1,25V=132.5W
--------------------------
162.5W at a max frequency of 2.6ghz
add a higher frequency and amd would be in the same range as intel.... worse case figures are useless.
