So the 65w is how much heat dissipates, not power consumption?
Sort of...most people use TDP as a power number, but of course they're completely wrong there. TDP is the guideline that the CPU manufacturer gives to OEMs for building cooling solutions.
AMD and Intel have 2 different philosophies on what the number should be (Intel gives TDP as the highest expected temp, and AMD gives the absolute theoretical maximum temp).
However, neither TDPs represent power usage...
The reason everyone quotes TDP as a power number is that it's the only spec they can find that actually has a power symbol in it (e.g. 65w)...it has nothing to do with actual power use, but people would rather quote something that's wrong than nothing at all...
The problem is that finding an actual power usage is quite difficult and it changes depending on what app you're running...
Fortunately, the people at Spec.org are currently developing a power usage benchmark that should be out by the end of this year...
Edit: As an interesting example, if Intel or AMD built a CPU that came with it's own phase change cooling built in overclocked it like mad (say a 3.6 GHz FX chip), it would obviously suck up a LOT more power but it's TDP would actually decrease...
