What is the question exactly?? I have AMD Athlon XP 1700+, it runs at 1.6Ghz and can work in Dual Processor mother boards just fine.
AMD also makes the Athlon MP processors for Multi-Processor systems and they run at about the same speeds as the Atlhon XPs. These chips have the new internal architecture to make them more PPC-like.
I'm waiting on the shipping of my iMac.... can't wait.... I ordered it on 1/7/2002.
