Actually, Intel didn't change anything about internal design to accomodate SSE. It wasn't until the AVX registers that they bothered to change from a data-ful ROB to a data-less ROB (the latter was used by the P4).

I'd also point out that AVX 3-op and FMA are much more distruptive to the core uarch than vectors. That definitely forces a change in uop format.

Yeah SW prefetch is really tough to get correct. That being said, it actually works for Java and other dynamic languages where the run time has a good deal of visibility into the programming.

I prefer Intel's approach to unaligned. Sure dealing with page crossing sucks, but it is even more problematic to make paging visible to programmers.

Transactional memory is harder to implement on relaxed ordering models (e.g., ARM, PPC), since it's technically stronger than processor ordering (i.e., x86).

Generally I'd agree with you. The problem is that quantifying those effects is very difficult. I've talked with Andy Glew, Bob Colwell, Mike Haertel and probably a dozen other architects. They all say that x86 imposes overhead, but nobody thought it was every >10% and many suspected 5% was a good guess.

I'd say it's worth about 5-10% performance on the CPU core - all things being equal. OFC, things are rarely equal in the real world.

I don't think comparing BDW or HSW, which target from tablets to servers, to Apple's phone/tablet SoC will necessarily yield a lot of information.
