This is just out of curiosity, but how much faster is Phenom II than Athlon 64 at the same clockspeed, same core count? And for that matter Phenom II to Phenom I? Besides die shrinks, what specifically makes it so much faster clock for clock (depending on how much faster it actually is)? And also (this is just pure speculation so dont get all mad with me) how much faster clock for clock do you think Bulldozer will be compared to Phenom II?
