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. -- "Never put off until tomorrow what you can do today.
