Specs would be somewhat out-of-step with recent competitors
For its A8 processor, Apple is planning to boost clock speeds to 2GHz or higher, but stick to just two cores, says Chinese site cnBeta. The A7 used in the iPhone 5s, iPad Air, and Retina iPad mini is a dual-core 1.3GHz chip. On top of the speed boost, the A8 is expected to upgrade from 28nm manufacturing to 20nm.
Some rumors have suggested that Apple might make the jump to a quad-core processor in 2014. Many rival Android and Windows Phone devices do use quad-core chips; the A7, though, sports an optimized 64-bit architecture, which may reduce the incentive to add more cores. In many cases, iOS apps still aren't fully leveraging 64-bit support.
The A8 should appear in new iPhones and iPads due this fall.
