Not that it's for sure, but M3 is probably coming out late this year/early next year and will be on 3nm, so once again having a huge node advantage. Just seems like Apple will have the latest node before everyone else for the foreseeable future.
Next year it’s likely all iPhones (plus possibly iPads) will also be on the new process.
It looks like Apple sells around 200 million iPhones a year, and the two pro models are somewhat more popular combined than the non-pros.
So even if we assume 2/3rds of Apple sales are older models, the pros would still need around 40 million chips on the new process in the first year.
For comparison it looks like AMD sells about 80 million chips a year, across all CPU models.
