Mr. Anon - I think what the most suited than SMP is supposed to mean is that since the single chip contains multiple cores (hence like 4 chips squeezed into one) and the fact that they can all access each others mem is more effecient (programing / space / cost / heat / power - wise) than having to manually handle multiple CPU's all seperate and having to move data to external memory for other's to get their hands on it.
This is not true... AMD originaly thought about using dual cores for the Sledgehammer, but this will not happen until they get their 0.09micron fabrication online.. This will be in the second half of next year.
Btw, Clawhammer will be out in October this year, and Opteron(Clawhammer DP and Sledgehammer) will be out in Q1 2003.
