Recently we got a picture of Apple’s latest chips, this might be upcoming A5X chip.
Apple calls this a component a single-core version of the A5, but microphotography reveals the presence of two complete cores, with one apparently disabled. What’s much more revealing is the discovery that this A5 appears to manufactured on a 32-nanometer Samsung process, rather than the 45-nanometer used for the normal dual-core A5 and A5X.
The theory goes that Apple’s been testing the reliability of this process by making these single-core A5s with a hidden, disabled core.
Assuming things have been going well, we’d be likely to see 32nm chips in a lot of upcoming Apple gear.
