Citing sources, AppleInsider claims Apple is not only going dual-core for their rumored iPad 2 and iPhone 5-bound Apple A5 chipset's CPU, but also its PowerVR GPU as well.
the company will not only be upgrading its video core, but also going to multiple cores, a feature that is designed into the SGX543 design. The most likely configuration of Apple's next custom chip is reportedly the SGX543MP2, which pairs two SGX543 cores to work as one, offering around four times the capability of the previous A4 in graphics and video tasks.
The SGX543 core is designed to parallel as many as 16 cores together, in a way that is transparent to higher level software, meaning that apps don't have to be rewritten specifically to benefit from the new speed boost. Imagination supplies intelligent core management that automatically determines the number of cores available and accelerates the graphic tasks by distributing them across the available cores.
Hey, all that power certainly would come in handy if iPad 2 really does have a 2048x1536 Retina Display...
