The Socket 754 Sempron is an Athlon64 (Newcastle?) with half the cache
and 64-bit extensions disabled. It's a completely different beast to
the Socket-A Semprons, which are just Athlon XPs with a different name
and a higher model number (and hence a higher price).

reading a bit more web stuff, i see:
sock a is k7
sock 754 is k8

[seems Sempron 3100+ is still the only semp k8]

Socket A Sempron will eventually be targeted at the extreme budget line of
computing with the Sempron 2200+ clocked at 1.5GHz and priced about where
we can find 1.2GHz Duron processors... looking forward to testing some
extreme budget systems based on these processors.


[looks like retail k7 semps are mostly 2800+ already. 2200 is gone? 2400
going.]
