The Apple S2 is the integrated computer in the Apple Watch Series 2, and it is described as a "System in Package" (SiP) by Apple Inc. It was revealed in September 7, with very little info about specifications. Apple says its two cores deliver 50% higher performance and the GPU delivers twice as much as the predecessor, the Apple S1.
It uses a customized application processor that together with memory, storage and support processors for wireless connectivity, GPS, sensors and I/O constitute a complete computer in a single package. This package is filled with resin for durability.
The device integrates discrete components like Wi-Fi, Bluetooth, GPS, NFC, touch controller, accelerometers and RAM into a single package.
