The difference between THAT figure and the figures shown in the review is the true power draw for the card.
Performance per watt statistic should be based on this figure.
statistic = performance / (draw - draw at dead idle)
I think that may fundamentally change your charts. (And is much closer to the truth).
not true, while it may work for idle, it will not work for under load.
if you look at the idle power draw chart you see that the system with 4670 consumes 179W in idle. according to the numbers at a ht4u review where they measured just the card's power draw a 4670 consumes 8.3W in idle. under load we see 203W where ht4u sees 64.2W power draw for that card. our perf/watt scores include a 150W system power draw offset for this. sufficiently accurate in my opinion to reflect power draw
