   Wow, that's old.  65nm die.  They're now down to about 8nm.   
      
   I'm surprised it runs Rosetta so quickly though, it thoroughly beats my Q8400   
   which is the next level up, although mine is a 4 core so it does twice as many   
   things although at half the speed.  I have noticed some projects run better on   
   some CPUs and some    
   better on others - I guess they keep changing the instruction sets and   
   altering what they're best at.  Graphics cards are even worse - I deliberately   
   bought some that are several years old, because they're really fast at high   
   precision calculations,    
   which they've all but removed from the newer ones.  But it's what the Milkyway   
   project needs.  But not what games need, which is what most are marketed at.

   I only put it on if I want to see what it's doing.
