Core clock speed, alone, is an irrelevant factor in the overall performance. It typically only makes a difference based on chip architecture, bus speed, memory access, and chipset performance. The Sun box is a RISC platform, right? I'd be interested in your comparison specs, if you can dig 'em up. I'd bet a few bucks that a dual Opteron(2.0Ghz-2.4Ghz) would smoke a Dual Xeon-MP of any current speed. I've never put them side by side with exactly the same peripheral hardware. A Xeon is basically just a Pentium on steroids. Have you looked at the Opteron whitepaper and architecture specs? The potential bandwidth those things have, as n-way configs, is totally awesome. I'm sure even a single 100 series, on a dual-board, will smoke a single Xeon. Check out the 800 series - if you've got a bottomless wallet, you can run an 8-way Opteron. *drool* > > You can probably imagine what the Sun engineers reaction to that was!
