AI claims that Apple is moving to dual-core SGX543 graphics, up from the A4's single SGX535 GPU (also known as the PowerVR 535). What's particularly great about this move is that the graphical power improvement is rated at around 4X the current generation -- which makes a true 4X resolution iPad "Retina Display" upgrade seem much more of a possibility. We're also starting to see 1080p HDMI video output as a "default" spec in this year's generation of devices, so there's no reason Apple will want to be left out -- particularly in the Apple TV -- and these dual graphics cores could handle that easily.
