Using this formula (tdp*(ocmhz / stock mhz)*(oc vcore/stockvcore)^2

and this underclocked voltage of .93v (stock 1.18):

Applying a 700MHz clock, I get 118.52Watts.
Yeah, the calculation works, but you can't really take a random post from a random guy on a random board as the basis for how 10 million+ dies are going to run. Hell, even the info there is incomplete. .93 at what clock? What mem clock? Stock? Is that with at least 24 hrs testing in 3dmark or something so that its validated stable? The voltage of 1.18 stock isn't even reference voltage(he also says 1.175, not 1.18), so it must be an OC board that is higher binned. The voltages in his sig don't jive with the numbers he claims either. Tomshardware did a test with actual stability testing on 6970s, and as far as confirmed stable goes, the best they got was 1.1v at stock 890/1375 and 0.98v downclocked to 500/1375. Barely over a tenth of a volt, nearly clock dropped in half.

This is all besides the point, 10 million+ console chips aren't going to be tweaked and overclocked and undervolted to their limits. If anything, they are going to be more conservative than video card reference voltages/clocks to ensure low rate of failure.
