I wouldn't say they are "quite" different. It's not like comparing Netburst to Core2, or I believe even original Core2 to Sandybridge. I may be wrong, I've not followed Intel cores from a micro-architecture POV too closely. If anything it's typical for a newer micro-architecture to perform the same at a lower clock speed. > I'm sure we're > looking at different cache sizes, different behavior for the > hyperthreading, Is there something specific you are thinking of? The Xeon E5-4650 has 20M "smart" cache organized as ??? The Xeon X5690 has 12M "smart" cache organized as ??? I know the AMD cache hierarchy for L1 I&D, L2, L3; but I'm not seeing this as clearly spelled out for these Xeons. > etc. I'm sure others would be greatly interested in you > providing the same benchmark results for a recent snapshot of HEAD as well. 10-CURRENT results were in http://people.freebsd.org/~obrien/jbm/vanitygen/vanity-perf-graph.png as "fbsd10".
