We know that Apple will use new A16 Bionic processors for the iPhone 14 Pro models this year. A new leak Ming-Chi Kuo has emerged claiming that TSMC will use the same 5nm manufacturing process for A16 Bionic chips that it has been using for the past few months. It is the same one that was used for A15 Bionic processors meant for the iPhone 13 lineup.
TSMC is reported to have 3nm and 4nm processes under development but they are not ready for prime time yet. It is speculated that it will take at least until 2023 before we can see these under mass production. This is the reason chipmaker has decided to stick with the 5nm process for one more year.
The move means one should not be expecting huge upgrades between the current iPhone 13 models and the upcoming iPhone 14 models. There will surely be minor performance and power efficiency improvements but nothing huge. Another thing to keep in mind is that the A16 Bionic chip is said to be limited to iPhone 14 Pro and iPhone 14 Pro Max. The other two non-Pro models in the family will come with the current-gen A15 Bionic chip.
Kuo further says Apple will continue with the same CPU architecture from the M1 processor for new MacBook Air models. This is because the newer M2 chip is reportedly not yet ready for release. There is also a possibility that the company may use the same M1 chip under a new name for marketing purposes.
