Thunderbird vs. Athlon XP processors...

[Tom]

I have an older A7V133 with an Athlon Thunderbird 1GHz processor. What is
the difference between this older processor and the newer Athlon XP
processors? (other than speed, of course) Do the XP processors run cooler?
Just curious....

Full support for Intel's SSE instructions (Opteron supports SSE2)
An improved hardware data prefetch mechanism
Enhancements to the Athlon's Translation Look-aside Buffers
Smaller die size (.13 vs .18) = Lower power consumption
On-die thermal diode

Bartons may run even a tad cooler due to more core surface area
contacting the heatsink.

Yes and no. The original Athlon XPs with the Palomino core were still
0.18µ parts, but did run cooler than the TBirds do to various other
improvements. The move to 0.13µ with the Thoroughbred allowed using
lower core voltages, wheich in turn reduced the power consumption for
clock cycle again. Without lower core voltages, you'd only get higher
leakage currents (which are generally relatively low with Athlons as
opposed to 0.13µ Pentium IIIs and 4s, but have increased with the die
shrink).

Yep your right, I forgot the Palomino was still a .18, things sure move
slow in the tech world! ;p
