DailyTech's got photos of the benchmark results. Looks like AMD had better hope for some clock speed increases at launch time, else they'll still be lagging quite a bit behind the seemingly dominant Core architecture.

"Cinebench completed the default benchmark in 27 seconds for the 1.6 GHz K10; 17 seconds for the Intel Xeon X3220. The Kentsfield Xeon was 58% faster with a 50% higher clock frequency for Cinebench."
