By all accounts I can find Itanium performance was good, perhaps even great when writing assembly. It seems to reinforce the point that ISA doesn't really matter.
But let's be clear: Of course ISA matters. It's just as trivial to make a bad ISA as it is a bad syntax. But does the ISA of modern superscalar processors matter? Probably a bit, but certainly not a whole lot.
