This is a 32nm part....the Apple A5X is from Samsung at 45nm. Did Samsung save their 32nm capacity for its own smart phones? Did Apple choose to take the A5X in 45nm from Samsung. -----
Apple is already using Samsung's 32nm process for some A5 production. It's only a matter of time before all the A5 family move to 32nm. As for the A6 (in the iPhone 5), it's too early to use either Intel's process or replace the ARM core with Atom. Expect Samsung again (@32nm).
