An ARM-based system-on-chip (SoC) family from Apple that provided most of the processing in iPhones, iPads and iPod touch devices until 2021, when Apple began switching to the M1 (see
Apple M1).
Using the RISC-based ARM CPU architecture, the Apple A series chips provide the equivalent processing power of desktop computers launched only a year or two earlier than the mobile product. Following are all the A series SoCs Apple has used since 2007, including models prior to the A series. The "X" suffix denotes a higher-performance version of the chip. See

Apple S, W and T series
The S chips are dual-core processors in Apple Watch. The W series refers to wireless chips in AirPods and the Apple Watch. The T series deals with Touch ID and security in MacBooks and iMacs.
