My understanding is the unified RAM on the M-series die does not contribute significantly to their performance. You get a little bit better latency but not much. The real value to Apple is likely it greatly simplifies your design since you don't have to route out tons of DRAM signaling and power management on your logic board. Might make DRAM training easier too but that's way beyond my expertise.
