I don't think Intel will beat ARM in power consumption. ARM chips are just one processing node behind, so when Intel will be at 14 nm, ARM chips will be at 20nm. Also Intel is still struggling to get just one Atom core to a low enough power consumption level. They can't improve the power consumption and performance in the same time. That means ARM chips will still be ahead for years in power consumption and performance (or performance/Watt). From what I've noticed right now an Atom chip is like twice as expensive as a similar performance ARM chip. So it will be interesting to see if they will ever overcome that, too. Intel has never really liked making Atom chips because they make so much less money on them than on their other chips.That's why they haven't really improved them since 2008 when they launched Atom. But they need to make SoC's, because ARM chips improve ~2.5x every 12 months, that's about 4x every 18 months, so twice as fast as x86 chips currently. That's why Intel is saying they want to start making SoC's and double Moore's Law. Because ARM is already doing that! But Intel won't have their 22nm 3D Atom until late 2013 or early 2014. The 32nm one won't be competitive. And I doubt the 22nm will be, too. It might be competitive in power consumption by then, but it won't be in performance, since ARM chips will keep the same low power consumption that they have now, but will increase performance 2.5x every year by then, while Intel can't do both in the same time.
