For all the hate those Atom chips are often underestimated - clock for clock they can match desktop Core 2 (as long as the cooling is upto scratch) while using a fraction of the power and producing a fraction of the heat which is actually quite impressive - sure they aren't going to compete (with all the extra baggage) against stripped out ARM cores in specialised application but you can run a full Windows experience in pretty tiny devices now.
But that itself isn't any kind of achievement in reality. Take out I/O and you can half the power of a lot of chips. The first bobcat core(again done on a tiny tiny fraction of the budget Intel put into Atom) was 10W and aimed at low end laptops, just turning off all but one sata and one usb port and they got the chip down to 5W. How many generations ago was that and bobcat while more efficient than Bulldozer, wasn't a brilliant core, just not bad. If that had gone through two die shrinks where would that be? The fact is most people don't want windows on a small device, it's too bloated and most windows type software is simply too big and not efficient enough for a phone so the ability to run it belies the actual demand to run them which is why windows phones aren't at all popular. Consider how many people actually have windows on a laptop or desktop, so theoretically a windows phone would be perfect, easy to sync everything and everything familiar, yet despite utter domination of home computing Windows isn't liked on phones.
The fact is Intel spend more on Atom than most mobile companies do on their chips, what it can or can't do is basically irrelevant, how successful the chip is in the market they are targetting does, everyone is doing FAR more for FAR less than Intel. Also what success Intel has had in tablets/mobile, is seemingly mostly down to buying design wins and subsidising chips to the point companies basically would be mad to not at least offer the devices for sales because the few they would sell would be at better profit due to effectively free chips.
Intel could make an ARM device, they could make an x86 chip with zero support for windows and fund the development of their own android like ecosystem for phones with ease on their R&D budget yet what they've achieved is chips no one wants, devices no one wants and they've spent billions to subsidise what sales they have achieved.
Clock for clock matching Core 2 on a fraction of the power multiple process nodes and many technology steps down the line isn't impressive, it's pretty much the bog standard chip they should have. How good would bobcat be with 2x the clock speed and on 14nm without any architecture improvements over the past what, 7 years or so? It could easily be 1-2W with the ability to run windows and have pretty decent performance.
