Different versions of Radiate report different numbers. This in itself is troubling. To further complicate matters, some sites calculate a CPU's wattage with an equation that is a ratio of stock to overclocked speed and voltage. So for example a TBird 1.4 at 1.75V will have a different output than a TBird 1.0 with its bridges adjusted to run at 1.4 and 1.75V. Troubling again. Further complication is the assumption that fsb doesn't affect anything and only raw MHz matters in heat output. Is this valid? I dunno (any takers?). There is a pretty good read at benchtest.com on this topic:

Look at the Stress Test section. His estimate is around 88% of theoretical load (not so far off from Cathar's 81%). My new and improved diode reader should be here next week with 0.125C resolution. I will posthaste compare different "100% CPU load" programs.
AMD has programs that will actually load a CPU to 100% (their words not mine) but they aren't sharing.
