BlueFin Research Partners analyst Steve Mullane cites the supply chain, notably Samsung, in the report, which claims the manufacturer was not properly equipped to produce the 28nm A6.
Reads the note: "[Samsung's] Austin logic fab - supports the mass production of the 45-nanometer AAPL A5 processor, and is ramping on a 32-nanometer process. Since the A6 processor is based on a 28-nanometer process, we believe the 32-nanometer ramp validates the recent rumors that the iPad 3 will likely use a higher speed, die-shrink version of the A5 dual-core processor, named the A5X processor, as opposed to the next-generation A6 quad-core processor."
If accurate, the A5X will certainly be powerful (perhaps even with a clock speed of 1.8GHz or higher) but with Android devices already out with quad-core chips, and more coming, Apple may need to step up its other features.
