Xeon vs Opteron?
The Xeon 5600 series is either 4-core or 6-core.
The Opteron 6100 series is either 8-core or 12-core.
It would seem that the Opteron is the better compute server,
especially since most SuperMicro chipsets support 50% more memory in
the Opteron than Xeon. But then why is the Xeon more expensive?
Are there some features I don't know about that make the Xeon that
much better than the Opteron?
we find that a given clock speed the Xeon is about 75-100% faster for
heavy math and memory intensive operations. Also the dynamic CPU speed
adjustment and under-clock for unused parts means you can get another
~40% boost through the use of the TurboBoost facility.
However, if you need more CPUS for more throughput, the Opteron may
still be a good choice. It depends on your application.
