E2010 Calculator, Megacycles, SPECInt2006, and Cores…Huh?

October 12, 2010

“…Since the release of v12.8 of the Exchange 2010 Mailbox Server Role Calculator, I have received several questions with regards to the changes in the processor input section.
In particular, the one question that keeps coming up is “Why doesn’t the CPU results change when I change the number of cores (e.g., change from 12 cores to 6 cores)?”
The answer is relatively simple: you didn’t change the SPECInt2006 Rate value when you changed the number of total cores that are in the system. Remember that the SPECInt2006 Rate value is a function of the server’s architecture, processor architecture, and the number of processors being deployed in the server. The same server with 1 processor versus 2 processors will have completely different SPECInt2006 Rate values…”
