Athlon MP vs Athlon XP

[Rayson Ho]

I found something interesting from AMD's developer site:

...processor also features the advanced _MOESI_ cache coherency
protocol to ensure efficient cache integrity in a multiprocessing
environment.

MOESI provides better performance in MP configurations, due to the
added O (owned) state. In theory, this can provide better cache
performance.

Also, please read the section "Why No Dual-Processing Support with
Thunderbird?" in the following web page:
