The iPad 3 was an influential and successful tablet, but an excellent example of an unbalanced system. In particular, the superb Retina display was not adequately matched by the GPU of the A5X, and represented a step backwards in terms of graphics capabilities. This article explores the challenges of designing innovative products given the underlying technical constraints, through the lens of the iPad 3 and its successors.
The new ARMv8 architecture is classically British; a clean and elegant 64-bit instruction set, with compatibility for 32-bit software. The 64-bit mode eliminates many complicated and awkward features and will foster a larger and more diverse ARM ecosystem with new licensees and applications.
Rumors aside, Apple will not switch their laptops to ARM any time soon. Despite Apple’s previous migrations, there are too many technical and business challenges and too few benefits. Moreover, Apple’s chip designers are better suited to enhancing the iPhone and iPad to fend off commodity Android systems. We look at the reasons Apple will stay with x86 notebooks for now, and how they might consider using ARM in the future.
