Apple's RAM isn't on the CPU die. They make the CPU and attach it to a substrate with RAM chips sourced from other manufacturers. Two separate dies (or three, dual channel RAM).
Most modern high end CPUs are like that now. It's more efficient to make the sub parts separately, often on difference processes so that the highest end ones are reserved for the things that need them and other stuff can use older nodes. They can then bin all the parts separately and reduce waste/down ranking further down the manufacturing process.
