SoCs
Starting with A6X, Apple added island/place codenames to SoCs, according to John (@nyan_satan) on the Hack Different Discord.

Starting with the M1 series, Apple additionally uses a suffix to indicate the multiplier of chiplets in the design. The "Chop" variant removes some portion of the "1C" design - for instance, M1 Pro (Jade Chop) is identical to M1 Max (Jade 1C), but with 16 fewer GPU cores. This is further explained with diagrams by John Siracusa on Twitter.

CPU cores
Since the A6, Apple SoCs have Apple-designed CPU cores. This table lists their names.


 * Swift: A6 CPU core design
 * Cyclone: A7 CPU core design
