While companies like Samsung, Qualcomm, MediaTek, and Huawei make their own chipsets for mobile devices, if there is one competitive edge that Apple has over the rest is the manufacturing process where thanks to their partnership with TSMC, Apple has managed to churn out chipsets built on a smaller process compared to the rest.
In fact, come 2022, Apple could hold a serious lead over the rest because according to a report from DigiTimes, they claim that 2022 could see Apple introduce 4nm chipsets. As it stands, the A14 used in the iPhone 12 lineup is built on the 5nm process, and it is expected that the 2021 A15 will maintain it.
For those unfamiliar, building a chipset on a smaller process essentially means an increase in the chip’s efficiency. This is one of the reasons why the M1 chipset used in Apple’s first Apple Silicon Mac computers seem to be performing so well, especially when compared to Intel’s processors which are built on the 10nm process.
We can only assume that the A16 will probably take advantage of the 4nm manufacturing process, along with whatever new Apple Silicon Apple will use that year. Right now it’s almost impossible to speculate what this translates to in terms of battery life or power, but it is most definitely a good thing.
