Last year, Apple distinguished the iPhone 13 Pro and Pro Max from the iPhone 13 and iPhone 13 mini in three areas: cameras, ProMotion displays and RAM.
However, Pu believes that Apple will be doing away with two of those elements for the iPhone 14 series.
Supposedly, Apple will return to 64 GB as the entry-level storage configuration for the iPhone 14 and iPhone 14 Max too, but this seems rather unlikely in MacRumors' opinion
