Whhhhhhyyyyyyyy would Apple release a new model of MacBook Pro where the only update is its power? ....
Until they can start using a 4 or 3nm chip, there’s no valid reason for refreshing the MacBook Pro other than greed. And given we always hear on MacRumors how they’re taking weeks to source components and ship custom MacBooks, it’s silly that they’re adding more demand to the strained supply chain. Not to mention, the practise is contradictory to Apple‘s “earth loving“ tenet.
Who says they can't do M2 Pro/Max on TSMC N4.
2020 --- A14 on N5 , M1 on N5
2021 -- A15 on N5P , M1 Pro/Max on N5P
Spring 2021 -- M2 on N5P ( which is just catching up on process. This SoC has volume since spread over part of iPad range as well as over 50% of Mac volume. )
2022 --- A16 on N4 , Pro/Max either N5P (do nothing on fab tech) or N4 ( do something )
The Pro could be riding the volume that the A15/16 are providing to pay for the R&D in a similar fashion as in 2021. N4 is in the same common design rules of the "N5 family". There is a some work to do but not major overhaul to shift to newer process. If the additions are small then Apple gets to make more chip/dies per wafer. [ Initial long backlogs of MBP 14/16" laptops isn't going to help Apple much. ]
The Max if targeted at laptops only could possibly go with N5P . A "max" that was suppose to be used in a dual , quad configuration would be more problematical if it doesn't get smaller. Pro and Max don't have to be on the same node anymore than the 'plain' M2 does.
A full 4 E core complex could actually lead to some battery savings in some contexts where didn't need any P core 'horsepower'. Small graphic core bump will help with better system longevity. Better RAM capacity options also.
I just hope a new model creates a trickle down price reduction for the M2 MacBook Pro so I can get a bit more power and the right amount of storage (1tb).
Probably not from Apple directly. Probably old models disappear. Temporary pragmatic sales by retail folks besides Apple (that will unload inventory stockpiles ) , but there is about zero need for Apple to keep making two sets of high end laptops for more than a month or so.
