AMD 12-core opteron versus 6 core xeon

I'd like to have seen a larger set of tests thrown at this one, but you have to love all the auto-enthusiast references in this anandtech.com review of the new 12-core Opteron versus the newer 6-core Xeon.

That's two, 6-core Instanbul chips bolted together. Reminds me a bit of the Pentium D with a much larger cache coherency problem (imagine how much of a problem this is going to be as we keep adding cores to chips).
