Recently, I accidentally fried my athlon xp 1700+ (palomino).
Needing to buy a new cpu (Arrrggghh... ) I started looking around for the cpu (AMD - palomino or Thoroughbred) with the lowest thermal demands, in order to cool it easier.
Here's some stats for the 1700+ cpu:
Code: Select all
Palomino Thoroughbred
-------- ------------
Manufacturing Process 0.18-micron 0.13-micron
Die Size 128 mm^2 80 mm^2
Voltage 1.750V 1.50V (For the 1700+)
Maximum Thermal Power 64W 49.4W "

Given this figures, one can see that the Thoroughbred core dissipates ~30% less power\heat.
HOWEVER, the die size has decreased by roughly 40%.
One can also see that the voltage has been also decreased (undervolting, anybody ?) by ~15%.
Now, the question is:
How does all this add up ? which is cooler (ACTUAL temp. wise) ?
Or, in a simpler phrase:
Does the 30%+15% decreases makes up for the -40% die shrinkage ?
PS:
I know this matter is a bit more complicated then that - just wrote it loosely for easy reading.
My guessimate is that the palomino larger die size prevails...
Anybody knows (preferably 1st hand info\experience, or some article\review on the web) the same\any differently ?
