Found an interesting review of the new Intel Quad Core CPU at tweakers.net:
Quad Core Review
They've also got some great reviews from earlier last year:
Xeon Woodcrest vs. Opteron Socket F
Sun UltraSparc T1 vs. AMD Opteron
Their database tests are read mostly, running a forum I believe. They list TPC, but I'm not sure they test the different database versions on each one or what.
