I hate to sound like a conspiracy theorist, but with regards to benchnmarks, I am now at the point where I want to know what compiler a commercial program was compiled with.

Cinebench is highly Intel optimated thats not new, at least for 64 Bit operating System Cinebench is forced to use SSE2 on every processor. Thats one explanation the Phenom does much more better with 64 Bit in Cinebench except the better 64 bit implemetation on AMD CPUs

For example (Cinebench)
32 to 64 Bit on a Intel system gives you an extra boost about 10 %
32 to 64 Bit on a AMD system gives you an extra boost about 20 %.
