M1X vs M2X — What should Apple put in the next MacBook Pro?
(iMore iPhone)

Why would Apple put an M1X into the MacBook Pro and iMac Pro if M2 is just around the corner? Why not just wait and use M2X? Well... Numbers and letters If Apple sticks the naming conventions they`ve been using for… the last decade of silicon, then the number on the chip means the generation of the silicon, and whether or not it has an X grafted on the end means whether or not it has extra cores and other features grafted onto the package inside. That`s it, that`s all… Kinda. I`ll get to M2X in an intel TDP hot minute, but it`s a little more complicated than that. Why? Because Apple is currently on the A14 in terms of silicon generation, and yet, instead of using M14 for the exact same silicon generation on the Mac, they decide to restart the numbering with 1. M1. Even though A14 and M1 have the same Icestorm efficiency cores, Firestorm performance cores, and no such cool codenamed graphics and neural engine cores. The M1 just has more of the eCores and pCores than the A14....
