MacRumors forum member commander.data spotted a part number on the A8 revealsing that the package-on-package contains Hynix RAM.
Based on Hynix's part number format, the character in the eighth position reveals the amount of RAM in the package, with an "8" denoting 8 Gb (1 GB) and a "B" denoting 16 Gb (2 GB). While it is a bit difficult to read the part number clearly given the distance and angle in the photo, our staff and several posters in our forum agree that the character very much appears to be an "8", indicating 1 GB of RAM.
Check out the photo below for a close up look at the part number. If you haven't already seen the leaked logic board photos click here. Feld & Volk has also managed to combine leaked parts to assemble an iPhone 6 that powers on. Watch that video here.
