For the roughly 150M New iPhone Unit sold every year, Apple needs just one SoC. One. And it could be reused next year.

For the roughly 25M Mac sold every year, Apple needs lots of design with different TDP. Fanless TDP sub 10W for MacBook, 15 - 25W for MacBook Air like. 35W for MacBook Pro, Upto 100W for iMac, and up to 200W for iMac Pro and Mac Pro. That is around 5 design variation for the 25M unit.

I still don't see how Apple would do it. Especially for the Pros, why would you design CPU aimed at 100W+ when they represent less than 2.5M unit per year. A lot easier just switch to AMD Zen 2 when the timing is right.

You forgot the 15-inch, so make that six.
