Furius92,
Sorry if I offended you or made you furious (pun intended
)
I believe that the wafer size was reduced to the .13 micron allowing for lower vcore settings, thus lower temperatures. Unfortunetly, AMD reduced the die size by roughly 38% which does not allow lower heat dissaptation compared to the XP core size,. plus AMD did not increase the amount of transistors in their design (although the .13 design will allow an increase in transistors in future designs for the Barton and Clawhammer). It is well known that AMD is concentrating on the formentioned designs rather than the Thoroughbred
The link you provided does not include detailed comparisions about CPU temperatures. Nor can I derive any actual reduction in CPU temperatures from data provided.
Anantech stated that there is a 12% reduction in heat based on the "Typical Thermal Power" of the Thoroughbred of which I believe is derived from the vcore rating. I highly doubt that the size of the die was ever computed in this calucation.
Maybe this accounts for the reason the Northwoods are running so cool because they are based on the .13 micron technology PLUS they running off a much larger die size (heat spreader) allowing better heat dissapation.
