> Intel and AMD refer to their systems as SoC since Apple started doing custom SoC
Intel and AMD refer to their systems as SoC since they integrated the north bridge (which includes the memory controller) into the chip, has nothing to do with Apple.
> CPU’s main I/O ports
That's a weird definition. Most architectures don't have "I/O ports" and use memory-mapped I/O exclusively. And even if we read that as "any kind of I/O pins" and go back to the

part: the vast majority of mobile SoCs in the 2010s use external RAM (and storage). The memory controller is onboard and the external connection is directly to DDR3/4/.. chips.
