blauboad,
If the HP announcement pushes Intel to release its x86-64... or at least announce it... what exactly would that do to AMD stock? Any guesses?
Let's consider Intel alternatives:
1.) stick to Itanium
The best for AMD, less likely after today's HP rumor
2.) Go with AMD64 compatible extentions
2nd best alternative for AMD. Much more likely after today's HP rumor. 2 to 3 vendors (or 4 including Fujitsu Siemens) selling Windows AMD64 will make it less likely that Microsoft and these OEMs will support Intel's effort to push non-compatible instruction set. (As a colateral damage, Itanium suffers mortal wound)
3.) Intel releases non-compatible x86
Worst for AMD, and much less likely after today's HP rumor.
So #2 is the most likely scenario, which happens to be a decent scenario from AMD's perspective. It remains to be seen how much lead AMD has, how far along Intel is on this road. I hope that Intel has been faithful to the Itanium mirage for a very long time.
