  Well, same clockrate, ~99% same architecture, same cache, same memory...
You can't expect miracles.

  In most other 32/64-bit processors (such as UltraSparc and Mac) you
actually get something like a 5% slowdown when you compile the exact same
program to 64-bit compared to the 32-bit binary (this is because pointers
take twice as much space and thus caches fill a bit faster).
