Evidence of Quad-Core Chips Shows Up in iOS 5.1 Betas


Submitted by Dan; January 06, 2012
9to5Mac reports that evidence of support for quad-core processors has shown up in beta versions of iOS 5.1, lending support to claims that Apple's forthcoming A6 chips will see a doubling in the number of processing cores. The references to quad-core iPhone and iPad chips come by way of a hidden panel that describes cores that are supported by iOS device hardware. The updated core management software includes an option of /cores/core.3, and this represents a fourth available processing core. The report notes that single-core processors such as the A4 found in the iPhone 4 and original iPad fall under a "cores/core.0" designation, while dual-core processors such as the A5 in the iPhone 4S and iPad 2 are covered by a "/cores/core.1" designation. The "/cores/core.3" reference thus suggests compatibility with a quad-core chip. Apple's A6 processor chip has been rumored various times to carry a quad-core processor, and has been presumed to be set for inclusion in Apple's next-generation iPad and iPhone models. It's unclear whether the production timeline for the A6 would support its inclusion in the iPad 3, which is rumored for a release around March of this year.
