I think it's tough to discuss only a subset of the vector extensions. It's true that AVX might be irrelevant for phones, today. But I doubt it will stay that way forever and you might see direct comparisons in tablets.

Do you mask out the lanes?

You're still using a single address right? It looks like they probably handle cache line crossing loads, which is nice.

I seem to recall from talking with one of the architects at ARM that they really got rid of all >2 cycle load/stores. I think the main motivation was simplifying exceptions, pipeline control and consistency.

That's probably OK because ISTR they now have 128b registers to deal with double precision.

It's all a matter of degrees. AVX will eventually hit low power chips, it's a question of when. Also, you will see VFP/Neon chips that are hitting higher power levels. So I think the comparison is quite informative.

I'd liken it to Bobcat vs. Atom. They are really different designs, aimed at different markets. They overlap in some areas, thus there is room for comparisons. But we all know that Atom doesn't hit 20W and Bobcat doesn't go under 4.5W. So they each have 'unique' areas.

Brands don't matter much, price points do. There are SNBs available for around $100. I'd expect that to drop with IVB.

Besides, with Jen-Hsun Huang talking about how Kal-El is faster than Core2...it's not crazy to compare it against Sandy Bridge : P

It's unrealistic to expect ALL of Intel's products to have AVX 1 year after the first SNB. There are still folks who want less expensive parts.
