Its pointless..theres no reason for the home user to use 64 bit right now... as far as will it beat the P4... well probably the latest northwood but i dont think so against Prescott.. theres too many tweaks to the arch. plus smaller process and more L2 cache... and if the 64 can only beat intel @ less than 9% ... Its not that good. Im not a fan boy but AMD needs to perform better than 9% cause a simple cache increase will close that gap ...only reason why it won was because the 64 has a On Die Memory controller that runs at core frequency ... new tech (Athlon 64) vs. Not as new (p4) ... which doesnt have an on die memory controller... put that in a P4 and im sure u would see things change.
