Current Apple Watch Lineup
Apple Watch Series 12 and Ultra 4 both use the S11 SiP, which keeps the 64-bit dual-core CPU and 4-core Neural Engine of the S10 but adds on-device Audio Intelligence for Live Rewind, Siri Recap, Shazam, and Sound Recognition. Only the SE 3 remains on the S10. As ever, the chip is not what separates Series from Ultra — case material, display size, sensors (depth gauge and dive computer on Ultra), and battery life are.
