Geek Patrol has
benchmarked the new (Core 2 Duo) MacBook Pro against the old (Core Duo) model.
"Moving from the Core Duo to the Core 2 Duo means 32-bit MacBook Pro performance is up 10% without an increase in processor clock speed. That's impressive! Even more impressive is the Core 2 Duo is 20% faster (when executing 64-bit code) than the Core Duo (when executing 32-bit code)."
