64 bit processors (combined with 64 bit capable operating systems) have 
the ability to address more RAM than 32 bit processors because 64^2 is a 
much larger number than 32^2... lots more RAM addresses).

This does not speed things up, though, until you run out of RAM, and 
start having to access the swapfile.

The processor's speed... MHz, GHz, etc., will determine how fast the 
processor itself can process instructions.
