Apple's M2 chip will reportedly use TSMC's enhanced 5nm node (N5P), an incremental upgrade over its predecessor. While its exact core configuration is anybody's guess, Apple will very likely be sticking to the big.LITTLE architecture. We're probably looking at a mix of four (or six) performance cores and four efficiency cores. Anything more would effectively render the older M1 chip obsolete less than a year since it has been around. We can expect some GPU/NPU improvements, along with some IPC gains, too.
A Bloomberg report from last year talked about Apple working on twelve-core and sixteen-core chips. The former is likely intended for consumer devices, while the latter could be earmarked for enterprise-grade applications. This sits in line with earlier rumours which talked about some new MacBooks coming out later in the year.
