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:
