Citing code found in a beta version of iOS 5.1, a new report claims that Apple is simultaneously developing its next-generation A6 processor, as well as an “A5X” variant of the A5 processor that currently powers the iPad 2 and iPhone 4S. 9to5Mac reports that the code makes reference to both an “S5L8950X” chip—said to be the A6—and an “S5L8945X” chip, which is said to be the A5X.
For reference, the original A4 was referred to as “S5L8930X”, and the A5 “S5L8940X”. A later report from the same outlet suggests that the A5X will find its way into the next-generation Apple TV, while the A6 will power the next-generation iPad.
