Currently, iPhones with A14 Bionic chip are made with the 5nm process, so the IC manufacturing process is good but can be improved. Now a recent report talks about By 2022, the Cupertino company could start adopting the 4nm manufacturing process.
The current Apple processor is really powerful but having this option on the table is good for boosting performance in every way. The A13 Bionics, for example, are processors that have 89.97 million transistors placed in the same space and in this case the new ones built in 5nm by Apple and TSMC would reach up to 171.3 million transistors for each square mm
All this would be from A16 by 2022
These new processors are not expected to arrive until 2022 and so this is something that is relatively far away. In current models the 5nm A14 Bionic adds 11.8 billion transistors, this already looks really good for Apple equipment, imagine if they get the 4nm digits.
The current A14 Bionic and the processor of the new MacBooks introduced by Apple with M1 processors are the first to use a 5nm architecture, so imagine what will happen. It is not clear that all of this will be implemented safely as there is still a lot of testing to be done today, but Apple’s path in this regard is clear and what TrendForce is saying is that the company seeks to move forward in this regard. There is no doubt that they will continue to improve their processors over time and this is just the beginning,
