Next-generation iPhones likely to focus on internal improvements.
Intel's 'Haswell' Desktop Processors Detailed for Spring 2013 Launch
Haswell will bring a number of enhancements to Intel's chip lineup, including faster performance and significant integrated graphics improvements delivered by the new Intel HD 4600 graphics package.
The Haswell desktop chips are likely to only make their way into Apple's iMac family, as the Mac mini uses mobile chips while the Mac Pro takes advantage of Xeon-branded server chips. Still, progress on Haswell sets the stage for further improvements to Apple's just-redesigned flagship desktop Mac, and mobile chips that will power most of the rest of Apple's Mac lineup should follow relatively soon after.
