It's actually remarkable how far AMD has come so far, and how single thread performance isn't as important as per core performance(there is a difference between the two). Without the i7, AMD would have been competitive with Intel per clock for most apps.
I know for the sake of the buyer, that site isn't too impressive considering they disable features like Turbo Mode, but its perfect for architectural comparison.
Some notes:
-It's a 4-thread optimized game seeing Hyperthreading does nothing for performance and its scaling reasonably well for clock.
-Core i7 is 25% faster clock for clock over Core 2 family
-Quad core gain over dual core is an impressive 45%
-Considering gains in IPC and SMT enabling 4 threads, Clarkdale at 3.0GHz should be playing with the Q9650
