Which wouldn't be so bad if the Pentium 4 being discussed was a 64 bit one.
Unfortunately it is a 32 bit one. Assigning no extra value to the Athlon 64's
64 bit mode doesn't seem to make much sense. In 2005 many of those
who bought a high priced 32 bit processor in '04 might become upset
that they didn't use foresight and buy a 64 bit processor. I wonder what great
64 bit applications we will see in 2005. I wonder what 32 bit applications will
be ported to 64 bits and show tremendous improvements in performance
when the 64 bit is run compared to the 32 bit version on an Athlon 64
or Opteron. Here is a link to one application already out in 64 bits whose
64 bit version runs 25% faster than the 32 bit version on an Athlon 64.

Other applications might show a much greater performance increase.
