This photo, originally posted at Chinese site WeiPhone, shows what is claimed to be the iPad 3's logic board, including an "A5X" system-on-a-chip. We're expecting a new processor in the next iteration of the iPad—though we thought an A6 would be the next logical step. If this photograph is real, the A5X model name may suggest that this piece of silicon is a bridging step.
According to MacRumors, the date code on the chip—"1146"—indicates that it was "manufactured in the 46th week of 2011, which would have corresponded to November 14-20". Elsewhere on the board are a pair of 16 GB flash memory chips from Hynix and a rectangular Apple-branded chip similar to the power management chips found in previous iPads.
