It's unclear to me what would have likely happened had AMD stayed on IA32 and Netburst been uncontested. Itanium was far too expensive for consumer machines and it seems very possible that Intel would have fumbled IA64 in a way similar to more recent AVX-512 and their big.little efforts. Easy enough to port XP to Itanium, hard to get those machines into Best Buy or the Dell catalog in any way that makes sense. Had AMD continued Athlon performance improvements and Intel still responded with a P6-derived Pentium M (which even in our timeline was 32-bit) it still seems like there would have been no volume market for IA64 and we still would have eventually ended up with an evolution of IA32 even if it came from Intel instead of AMD.
First thank you for generously understanding my post despite the vandalism that autocorrect did to it.
WindowsNT is remarkably well suited to porting to other arch. This was done on purpose to hedge against x86. Dead one day, reactivated the other. MS needed to brake the 4Gb barrier and they would have done anything to get consumer priced 64bit chips.
Itanium was a dog. We had an Itanium SGI "supercomputer". Everything about it that SGI designed was amazing (hot swapping cpus). The cpu was a dog.
