Expectations had been that the iPad 3's new processor would be called A6, considering that the original iPad shipped with the A4 SoC, and the iPad 2 shipped with the A5 SoC. If this photo is correct, that would mean the A6 will still be a quad-core processor, but that the iPad 3 will ship with a dual-core processor as rumored, the A5X.
The A5X chip, as shown in a forum post at the Chinese website WeiPhone, has a date code of "1146," which indicates that it was manufactured in the 46th week of 2011, or the week of November 14 - 20.
There are other details visible on the logic, board, including what appears to be a rectangular Apple-branded power management chip, corresponding to those found in prior iPad teardowns but with a higher part number, indicating an upgrade. Also seen are a pair of 16GB Hynix flash memory
In addition to an upgraded processor and a HD "retina display," the iPad 3 is expected to sport LTE support on both the Verizon and AT&T networks, and perhaps an upgrade 8MP rear-facing camera.
The form factor will be relatively unchanged, perhaps thicker (yes, about 1mm thicker, according to earlier reports) and maybe somewhat more tapered.
All will be revealed on March 7, at 10 a.m. PST, if everything holds are predicted.
