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.
