The more expensive intel processors also have L3 caches of 1-4MB.
Since intels processors are built with inclusive caches (data in L2 
cache is also present in L3) shouldn't the value used be that of the 
largest cache be it L2 or L3?

How much effct on performance does a wrong cache size value have?
