Retail AMD Phenom II X4 (Deneb) OC spotted

That is not what I said and yes I did anwser your question. The heat is generated by resistance. Resistance which SOI helps to alleviate now if you want to go on about how nice Intel is, fine. i7 is a great CPU no one disputes that but SOI does reduce TDP go look it up if you dont believe me.



Actually, ya they were. Not everyone lives in Denmark



By that arguement either all the money AMD and Intel spent on SOI was worthless or whomever packages Intel's processors needs to be fired because I have owned both AMD and Intel chips and by far since AMD went SOI their chips have been noticablly cooler running.

I guess the good results wit 45nm node are more due to Immersion Lithography technology along with overall well constructed process rather than the SOI.
SOI helps to decrease the power draw of the circuit, that is e.g:

Bulk 130W
SOI: 105W
(It does not mean that 130W SOI would generate less heat than 130W Bulk would!)

The only way to determine how "hot" a chip runs is to measure the wattage it draws from the motherboard. More watts translates to more heat.

If the practical max. power draw of PhII is 80W and the TDP is 125W(meaning that the stock cooler is rated for handling loads up to 125W), I'd understand how the PhII indeed "runs cool" - due to good stock cooler and "low" power draw.

It all sums to the power the CPU draws from the motherboard. If it draws 125W then it will run hot no matter what. If it will draw less, then it really might run cool.

Just a reminder: TDP rating is for cooler manufacturers mostly and does not really have anything to do with actual power draw of the chip - other than the fact that usually the power draw is more or less near the TDP.
