Designation Apple Silicon brings together all SoC, SiP and other chips designed by Apple. These chips use the ARM architecture and equip many devices and wearables of the brand. The production does not take place within Apple since the company does not have a foundry. This is TSMC, often ahead of the downsizing of transistors and theapplication of Moore’s Law, which is responsible for producing Apple’s chips, but the Cupertino company also called on the expertise of Samsung in the field several times.
The A series is probably the best known to the general public, it is she who equips the iPhone, iPad, iPod Touch, Apple TV as well as Homepod first generation. It will use a BIG.little ARM architecture, that is to say with powerful cores but consuming a lot and more economical cores but with lower performance as well as several graphics cores. Due to its presence in theiPhone, Apple’s flagship product, it is often the one that benefits from the latest innovations from TSMC and Apple engineers.
The M series was introduced in 2020 when Apple announced the transition of its Macs fromIntel towards its own architecture. It is also based on the ARM BIG.little architecture which serves as the basis for the A series but remains more powerful because the chip has access to moreenergy. All of Apple’s Mac range will be equipped with it by the end of 2022.
Mainly dedicated to Apple Watch, the SiP (System-in-Package) of the S series also equips the Homepod Mini. It includes processor, graphic heart but also RAM, storage and others modems dedicated to connectivity Bluetooth, Wi-Fi and cellular.
Apple also produces other chips with various uses:
- The T2 chip that equips Mac and Macbook since 2017 and fills the security gaps of processors Intel. It encrypts and manages the biometric information necessary for the operation of FaceID.
- The U1 chip which allows the use of ultra wideband on various Apple devices such as AirTags
- The H series that equips wireless audio devices from Apple and Beats such as Airpods Max, Airpods Pro but also Powerbeats.
