The AMD Athlon XP, MP, and mobile Athlon4 are based on the Palomino
core.  The 1Ghz+ Durons are based on the Morgan core, a Palomino
derivative with less cache.  The previous generations of Athlons were
based on the K7, K75, and Thunderbird cores.  What is a bit misleading
about the naming of AMD's processors is that at present they are all SMP
capable.  You can use dual Thunderbirds or Durons or XPs without a
problem, generally.  In fact, you can even use processors of different
clock speeds in an SMP configuration fairly successfully, though it is
not recommended.  What you pay for when you buy Athlon MP processors is
AMD's SmartMP technology.  SmartMP includes a more advanced cache
coherency protocol and an inter-processor "snoop" bus that allows the
processors to exchange data from their caches instead of going directly
to main memory all the time.
