The part ID # ends in BA, BP, or BN. All rated at 71C case (heat
spreader,
not die). Voltage is either 1.35 or 1.4V, and you can't tell which
until you
install and run the part (no joke)!

BA = Palermo. Has 256K L2 cache (or 128K for marketing reasons). 62W
TDP.

BP = Venice. Has 512K L2 cache. 3500+ and down, 67W TDP. 3800+ and
up, 89W
TDP.

BN = San Diego. Has 1M L2 cache.

TDP = Thermal Design Power aka "guaranteed never to exceed power". In
the
case of these newish 90nm CPUs, TDP has been _politically_ assigned,
not
technically. In every case, with no exceptions, the TDP exactly
equals the
TDP of the previous .13u CPU with the same performance rating.
Strictly
speaking, we can only be assured that the new 90nm parts will not have
_higher_ power dissipation than the previous .13u models. ;-)

Well, not really. Look at the 3500+s - Newcastle with TDP of 89W and the
Winchester & Venice with 67W.

I can assure you that the Winchester 3500+ runs much cooler than a
Newcastle... nearly 10C cooler at full tilt with stock cooling and similar
case.

I knew that George, hence the smiley face. I hear Venice is even
cooler than Winchester!

AMD's Thermal and Electrical Spec mentions BN and BP:
