AMD s AMD Tips On Dual Core Performance

A two-processor dual-core system clocked 5 clock speeds down from AMD’s
fastest part will generate performance of approximately 125 to 140 percent
performance of the dual-processor unicore system. A dual-core, dual-processor
system clocked at only three grades slower than the fastest AMD chip will
perform at between 130 to 160 percent of the performance of the base system.
Future versions of the dual-core Opterons/Athlon 64s may contain two or more
memory controllers to keep the processors fed with instructions. The problem is
that processor speeds have outpaced memory clock speeds, meaning that the
processor can be forced to wait for the rest of the system to keep up.

that processor speeds have outpaced memory clock speeds, meaning that the
processor can be forced to wait for the rest of the system to keep up. To solve
the problem, processors like Intel’s Montecito have added massive amounts of
level -2 and level-3 cache to store frequently-used data close to the processor.
