Apple is reported to be working on the M2 chipset for next year, which will serve as the direct successor to the M1. Fortunately, just like the M1 Pro and M1 Max designed for the new MacBook Pro line, the company is also working on their direct successors, presumably named the M2 Pro and M2 Max.

Unfortunately, the M2 Pro and M2 Max will not launch in the same year as the M2, according to Commercial Times. Where the M2 will reportedly be ready in the second half of 2022, the M2 Pro and M2 Max will likely launch in the first half of 2023, with the higher-end variants codenamed Rhodes. Like the M2, the two upcoming custom silicon will be mass produced on TSMC’s 4nm architecture, leading to improved performance and power efficiency.
