Cannon Lake is a weird red herring to bring in to the discussion, because it was only a real product in the narrowest sense possible. It may have technically been the first CPU Intel shipped with LPDDR4 support (or was it one of their Atom-based chips?), but the exact generation of LPDDR isn't really relevant because both Apple and Intel have supported multiple generations of LPDDR over the years and both have moved past 4 and 4x to 5 now. What is somewhat relevant as the source of confusion here is that Apple puts the DRAM on the same package as the processor rather than on the motherboard nearby like is almost always done for x86 systems that use LPDDR. (But there's at least one upcoming Intel system that's been announced as putting the processor and LPDDR on a shared module that is itself then soldered to the motherboard.) That packaging detail probably doesn't matter much for the entry-level Apple chips that use the same memory bus width as x86 processors, but may be more important for the high-end parts with GPU-like wide memory busses.
