That is expected to change in 2022 because according to the latest DigiTimes report, Apple’s 2022 lineup is expected to be using chipsets built on the 3nm process. This might sound rather technical to most, but the gist of it is that the smaller the process is, the smaller the distance is between the processor components.
This is like a driving route, where if the distance to your destination is shorter, you’ll spend less time driving and also use up less fuel. In the case of processors, it means that they will be able to perform more efficiently while being more energy-friendly. Whether or not the differences can be felt in real-life usage is a different story, but from a technical standpoint, it’s a good thing.
Next year is also where along with the A16 chipset, Apple could debut the M2/M2X/M3, so it should be rather exciting as far as technology developments are concerned.
