With all this 64 bit talk and hanging on Microsofts every word, it appears a lot of people expect Intel and Microsoft to drop a bomb on AMD64 in the next few months if not sooner.
Do you honestly believe that MS is generating an AMD64 OS that has nothing to do with Intel?
<Do you think it is AMD64 compatible? A superset of AMD64?>
Intel? Compatible? Are you joking? A superset? At least. Totally different? Why not?
<Do you think it is IA-64 compatible?> I don't even understand this question. Why would it be? That wouldn't compete with AMD at all in this market. IA-64 is a totally different market.
<Do you think it will be active in Prescott? Tejas?> Yes.
<What will its impact on Itanium be?> Nothing. Separate market. Your question should have been, "What will be its impact on AMD"?
