Was there ever a point in the Itanium's history where there were Itaniums that ran mainstream software with better performance than equivalently priced x64 processors?
- zlynx 9y agoThere were hand-coded assembly loops that were 3-4 times faster than x86, using Itanium's predicates and rolling register windows. But I guess you said mainstream. So unless you count database engines, I suppose the answer is "No." Today you can get the same vector performance using SSE4 and AVX. Almost all of Itanium's good stuff has been rolled into Xeon.
- gh02t 9y agoAs far as I know (which isn't very far, admittedly) they only really managed to reach parity with some performance gains over x86 in a few niches, but it's also a bit chicken-and-egg. It never had enough attention to really get the optimization and porting efforts it would have seen if it had been successful.
