The latest 1080p-capable Apple TV uses an A5 processor but it is based on 32nm architecture, the Chipworks crew found when they dissected the media player. The part number, APL2498, thus mainly differs from the previous-generation A5 chip (part number APL0498) used in the iPhone 4S by being based on Samsung Semiconductors' 32nm high-k metal gate LP CMOS process technology. The older chip used Samsung's 45nm LP CMOS process.
