The second page of http://www.overclockers.com/articles913/index.asp talks
about the possible strategies behind Intel's own implementation of x86-64
in their Xeon line (http://tinyurl.com/2lnhg).
Do you have a personal opinion about the hardware technology direction
with respect to the two competing architectures (x86-64 vs. Itaniums)?
