Itanium was primarily developed by Intel, Itanium 2 primarily by the HP team that also was responsible for the competitive PA-RISC chips. (Or so they say). In any case, Itanium 2 still outperformed much later AMD Opterons and Intel Xeons running at twice the clock in numerical workloads. That’s pretty impressive.
- twoodfin 2y agoThat’s my point: If the demand for high-end compute at the turn of the millennium had looked the same as the demand for high-end compute in 1992, Itanium probably would have conquered the world. But Tim Berners-Lee had a NeXT and some good ideas…

- hapless 2y agoYou have it backwards. Itanium 1, which had x86 and some limited hppa compatibility, had a ton of HP input. Itanium 2 dropped a lot of the broken ideas from Itanium 1 in favor of .... slightly better than the worst performance in the industry. re: numerical workloads, they achieved high performance on SPECfp exactly the same way as late-generation HPPA chips -- just throw more L3 cache at it until the number looks good. Not exactly engineering genius.
