    This iPad A4 chip from what I hear is an A9 cpu. The diagram shows it can be multicore. Anyone know if it is a single or multicore A9 inside this A4.

    Anyone know what kind of GPU is it running?

    The A9 is either a two core or four core chip, the A8 that the Snapdragon and the iPhone CPU is based on is single core.

    Cool that makes sense. Two CPUs one to handle the foreground UI and the other could handle other stuff. Would make for a speedy interface.

    I got this from the ARM site.

    Mali-400 MP GPU - Targeting up to HD performance on mobile phones, set top box as well as portable and console gaming, Mali-400 MP delivers multicore graphics processing scalable from 300 million to over one billion pixels per second

    Mali-200 GPU - the most widely licensed GPU from ARM today, using programmable shader capabilities to deliver stunning user interfaces, browsing and navigation on a broad range of devices in multiple product markets.

    Mali-55 GPU - the world’s smallest and most power efficient GPU brings hardware graphics acceleration to the most cost-sensitive markets.
