Silvermont supports OOE (at least for integer...FPU is in-order).
I'm kind of shocked that ARM has done: A12/A17, A57, A72, A53 in the same time it has taken Intel to bring out Airmont.
What is Intel spending all of that mobile R&D money on?
It's a bit easier to make small iterations of your architecture, and then go and license it, without ever actually having to worry about the timing of fabs and holidays and such.
All of those are fairly minor revisions to preexisting designs. They're still in low-hanging fruit paradise, so those minor revisions can bring them good boosts in performance and performance/watt.
That's not to say that Intel isn't taking their sweet time. They need to figure out how to lower their TTM without impacting their legendary QA. ARM seems so nimble in comparison, even (or especially?) Apple. Intel cannot afford to stray from reiterating once a year.
They're probably pretty strained, though. They're moving a lot of products to 14 nm -- Broadwell, Skylake, Cherry Trail, Broxton, SoFIA LTE-2, XMM 7460 -- and that's just what they've stated thus far. There hasn't been any point in the past where they've had so many products on their leading edge node. While individual product lines may be moving slow, as a whole, they've become much more aggressive.
All of this will have very positive implications on their cost structure. Intel had previously been missing the rising handheld tide that was lifting all of their competitors' boats. They're doing just about everything the need to be doing... but Cherry Trail and Broxton are definitely behind schedule. Merrifield and Moorefield were super late too.
Also, yeah, Cherry Trail is just unacceptably slow for the year and a half wait. Maybe they were planning on clock speed boosts from 14 nm to be larger in magnitude...
It seems like Intel has invested a lot more in pushing its big cores down the stack than in improving its small cores. I'm starting to think we are more likely to see a Core-M derivative in a flagship smart phone before anything Atom based.
Atom may be forever the cheapo-brand.
That's fine, as long as they make Atom cheap. They've burned over a billion as a result of not doing so -- you'd think accelerating Cherry Trail's introduction would be of high importance.
