AMD's very good with tweaking and speed binning a high TDP chip. Look at when 90nm matured, people were wailing 2.8GHz tops until later they released 3GHz and then a little later you see 3.2GHz which does 3.5GHz (seen with 5000+ BE as well). They do scale with those speeds as well.

This is why AMD's buying time with K10h. No one, and no one, wants to release above 130W TDP, they try their best not to even get close to that. Industry hates the sound of that, to them it means power/heat "problems" and reminds them of Prescott completely. Even Tejas did hit 5.3GHz in Israeli labs but power/heat:performance ratio was just too ineffective to be retailable.

Just keep in mind that TDP is what the thermal solution must be able to disspiate to stay below the Tjunction of a chip and ensure no damage. It is one part of the power consumed which is wasted as heat and the other part is what the IC's use up efficiently for their work. The CoolIt Freezone could only handle 175W maximum and did only around 3.3GHz with B3 QX6700 (~55C stability testing), so these chips with high TDP's are worthless for me on air to keep stable. Like I said elsewhere, max screnshots and benches, even I can run my E6750 at 1.35V for 3.76GHz, but stable inside a case 20C ambient? I don't think so, not even for 10 seconds under Prime95 torture. In fact it needs 1.454V BIOS and much more VMCH and VFSB to be stable, which is far hotter and more power demanding, open air, let alone summer and inside a case with 30C ambient. I would never buy a CPU that costs me more to cool than to buy another and have its equal or better performance.

And yeah, for those waiting to see power and temps of Phenom, I can show you that pretty damn soon, stock and overclocked.
