I don't think those are 'obscure'. The EV8 was supposed to. There's no telling how far they got in designing the EV8 but it will never ship. >>The Itanium doesn't get higher ILP from x86 code.

We were talking about Intel's design of its x86 processor, so I assumed you meant "smarter" designs that run x86 code. If you threw out the x86 restriction, Intel could easily and dramatically increase IPC (thus giving you your smarter chip). -Tom
