System-in-package in Apple Watch Series 2
From Wikipedia, the free encyclopedia
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 on September 7, 2016, with very little info about specifications.[2] Apple says its two cores deliver 50% higher performance and the GPU delivers twice as much as the predecessor, the Apple S1.[3] The S1P SiP shipped in the Apple Watch Series 1 is a stripped down version of the S2 that lacks the GPS functionality, it is otherwise identical.[4]
