    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.

  3. 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

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