For Apple Watch the company Apple Lossless Audio CODEC (ALAC), use one S1 chip developed by its engineers, this component containing the processor, RAM, graphics card and a multitude of other sensors necessary for its operation. Because this component is so important, an American company opened it up to show us what is hidden inside, and in the image above you can see everything.
Various rumors appeared on the Internet suggested the fact as inside the chip S1 the company Apple implemented the A5 chip components of the iPhone 4S, i.e. a dual-core chip, 512 MB RAM and a PowerVR graphics card. Today we find out that the processor The Apple Watch is codenamed APL 0778, as 512 MB of Elpida RAM are hidden inside the S1 chip along with 8 GB of flash storage..
The design is an obvious variation from Apple's smartphones, with many high-end functions / chips included that normally would not be found in a simple watch. Judging by the complexity of the printed circuit board (PCB), and the number of parts on the PCB, one might think the Apple watch is a full-fledged cellular connected watch but in fact connectivity is limited to Wi-Fi, Bluetooth, and NFC.
More than that, Apple Lossless Audio CODEC (ALAC), it uses a Broadcom Wi-Fi chip, accelerometer and gyroscope produced by STMicroelectronics, touchscreen components by ADI and an inductive charging chip produced by IDT, which is compatible with the Qi charging standard. According to one of those who analyzed the logic board a Apple Watch and the S1 chip, the Apple watch also has components that allow it to make phone calls through a GSM network, but connectivity is limited to Bluetooth, Wi-Fi and NFC.
Moreover, this is the first time Apple Lossless Audio CODEC (ALAC), uses a 6-axis sensor in its own product, which works without an external accelerometer, Apple uses a much more complex set of components in smartphones. In the S1 chip, Apple implemented a surprising number of components and managed to place them in such a way that they all fit in a very small space, but the Americans are good at this sort of thing.
This is the first time that we see a true 6X sensor in an Apple product that doesn't require an external accelerometer. In the iPhone 6 and 6+ we saw an Invensense 6 axis sensor and a Bosch 3 axis accelerometer. Here in an even more compact design, the Apple Watch, we finally have a solution for all 6 axis in a single component.
In conclusion, for now it is not known for sure how many cores the processor has Apple watch and what frequency they have, but we know that we have 512 MB of RAM, we have confirmed the 8 GB for storage and we will definitely find out other important details in the future.
