“So far, the new $399 iPad 2 (iPad 2,4 in Apple nomenclature) and third-generation Apple TV have been confirmed to use the new chip, but it’s also possible that there’s a new generation of the iPhone 4S with a 32nm A5 at the helm,” Anthony reports. “The original A5 SoC (system-on-a-chip), found in the first iPad 2 and iPhone 4S, was built on Samsung’s 45nm process. The A5X SoC in the iPad 3, which has four GPU cores instead of two, is also 45nm.”
Anthony reports. “By moving to Samsung’s 32nm High-K Metal Gate (HKMG) process, the new A5 processor (S5L8942) is 40% smaller than its predecessor, uses around 30% less power, and is significantly cheaper for Samsung to produce — thus, no doubt, allowing Apple to retain its fat profit margins on the cut-price iPad 2.”
