Nearly two weeks after the product’s official release, Chipworks has updated its earlier Apple Watch teardown to note several significant details, most notably that Apple’s latest processor uses a 28-nanometer building process that has already been leapfrogged by newer technology. The discovery reveals that the S1 — believed to be roughly equivalent in processing power to Apple’s A5 processors — can be readily evolved using the smaller 20-nanometer process used in Apple’s current A8 processors, as well as the cutting-edge 14-nanometer process that’s reportedly being used in the upcoming A9. This is good news for next-generation versions of the Apple Watch, as they will be able to easily fit faster or more power-efficient processors in the same space as the S1.

As highlighted in separate chip teardown and X-ray analyses released today by Chipworks and iFixit (partnered with Creative Electron), the S1 packs over 30 components into a resin-covered package, including everything from wireless chips, wireless charging, audio processors and sensors to the CPU itself. The CPU is again said to be Samsung-fabricated, continuing the unusual frenemy relationship between Apple and one of its chief consumer electronics rivals. Several of the beautiful iFixit/Creative Electron X-ray images of the Apple Watch are included below…
