Mobile processors have reached the point where they are so powerful that there's rarely an app or task that uses their full capacity, not to mention the 64-bit A7's prowess that will go largely underutilized for now. The next step, however, are the super-frugal dedicated processors of the future that can power supplementary always-on endeavors like speech recognition or movement sensitivity. Motorola used a dedicated low-power chip for the speech telling abilities in its X8 chipset, while Apple made a separate M7 one for the always-on motion sensing tasks in the A7, for instance...Source: http://www.phonearena.com/news/Intel-demos-mobile-chip-so-frugal-it-can-be-powered-by-wine-still-recognize-you-by-the-way-you-walk_id47482
