There is speculation, informed speculation and then there are people running at the mouth spewing crap. Semiwiki seems to be built around spewing more than anything.
One issue that always stands out when I see these sorts of articles is the glowing assumption that ARM devices are some how stuck on an old process technology and won't shrink anymore like Intel hardware does. That is rather foolish if you ask me.
Consider this, ARM processors Apple uses are built, apparently on a old process technology. This implies that Apple has to do nothing other than to shrink the process to get even lower power dissipation. Or they can add additional capability.
In any event I suspect there is a long term strategy to the move to ARM for all iOS devices. We may not know what that is but one thing is pretty obvious Intel will be trailing performance per watt for some time.
As to the multicore solution (better stated as a multi ISA) I don't buy that either. Intel would be able to easily emulate an ARM if power wasn't an issue. Power is an issue which is another reason not to go to two different processors on a chip.
Beyond all of that the referenced article was talking about Intel processors in the 3 to 7 watt range in the future. That is way way to much for Apples devices, ideally the SoC used in Apples devices need to be sub one watt. Right now it is understood that the processor int eh iPad can max out at seething over two watts which I'd suggest is a little too much for that machine. All of this suggest to me that Apple will aggressively drive down power usage in future devices. I would not be surprised to find out that Apple has a target of a quarter watts for a maxed out iPhone X processor of the future.

The multi-core solution will run both iOS and MAC OS. These processors will be built in 14nm and out the door late 2013 or 1H 2014. Intel will build a family of A6/x86 combo processors to allow low to moderately priced CPUs. Apple will have sole rights to the chips and can hide from its competitors the true cost of the CPUs. Apple MAC based PC will drop in price. On Intels side, they can continue to serve legacy x86 markets without a price conflict.
