Re <<Given where we are now, do you have any concerns in the future for T-bird at say 1.5GHz with on chip 256K L2 cache. Is this a non issue for Athlon for the remainder of the .18um generation.>>

Keep in mind that the interface between the die and heat spreader plate is a major barrier. Both AMD and Intel use some sort of silver filled epoxy at high pressures which gives h=35000 w/m^2.k, even at such high numbers there is large delta temp (not good), since the die is so small. Silicon itself has high thermal conductivity, so big die is good for thermal consideration.

My point is that since the T-bird will have a larger die, it makes life easier for the thermal engineer. I don't know what the power will be but I think up to 85 Watts would be no problem.

WatsonYouth based on Dan3's evidence that T-bird is on 100nm gates compared to Al Athlons at 120nm gates doesn't it appear T-bird is more of a .15u process under the .18 guidelines..

Your more of a expert on this than I.. Please comment.
