Earlier, it was reported that Apple planned to continue using TSMC's 5nm process in a16. today, Guo Mingxuan forwarded the news and released a roadmap of TSMC's release time** According to the roadmap, TSMC's 4nm and 3nm processes will not start mass production until 2023, so the new a16 processor can only use the original 5nm process.
Access:
Meanwhile, guomingpei revealed that TSMC's 4nm process is not significantly improved compared with 5nm, so it is reasonable for a16 to choose 5nm instead of waiting for 4nm**
However, although a16 has no chance of 4nm, it does not mean that it has no improvement compared with a15.
Apple will support lpddr5 memory for the first time on a16, and enhance CPU and GPU myocardial infarction, thus bringing some experience improvement**
It is worth mentioning that some users believe that Apple plans to "hold back a big trick" on A17 and directly adopt the 3nm process, but there is no substantive evidence for this speculation.
