The latest and greatest number - 200 W - is supposed to be the total heat output for the R600 core. Fudzilla states this number as coming from "reliable" sources - and this time, I am inclined to say that I think they are right.

As we know, there are two versions of the R600 card - the "big gun", measuring in at 12.5 inches, and the "pocket sized" 9.5 inch version. The big card will probably be branded as Radeon X2900XTX and will end up with OEMs only. The bigger cooler should prolong its lifespan, and keep it cooler overall. The shorter card has a massive dual-slot cooler with heatpipes.
