“ARM chip” is a pretty broad umbrella. Apple’s M-series is based on the ARM ISA, the microarchitecture is Apple’s own design, and the SoCs are built with very different cache hierarchies, memory bandwidth, and custom accelerators. I was simply using Apple as an example of another big player.

Well so is the snapdragon X elite, including the older snapdragons (anyone remember scorpion cores on QSD8x50?)
