Around the time of K8 being released, I remember reading official intel roadmaps announced to normal people, and they essentially planned that for at least few more years if not more they will segment into increasingly consumer-only 32bit and IA-64 on the higher end
Itanium was bonkers in lots of ways—very cool in others.
But this market segmentation idea just seems absolutely insane to me in a way I’ve never had anyone satisfactorily explain.
It requires Intel to voluntarily destroy the commodity economics that put their CPUs on a rocket ship to domination.
It’s as if they actually bought into the RISC FUD from the 1990’s that x86 was unscalable, exactly when it was taking its biggest leaps.
