According to a reported roadmap, Apple will move to 3nm chips in 2023 for both its Macs and iPhones. The third generation laptop chips are codenamed “Ibiza”, “Lobos”, and “Palma” and are expected to be variations of the M1, M1 Pro, and M1 Max.
Apple will stay with 5nm process for its SoCs in 2022, but they’ll tune the manufacturing process slightly. Additionally Apple is expected to produce a chip with two dies in 2022, likely meant for a Mac Pro.
The current fastest Apple Silicon chip, the M1 Max, is made on a single die – so we can expect essentially a dual M1 Max chip with support for as many as 40 CPU cores to be ready for a potential Mac Pro in 2022.
The report claims that the iPhone will follow in Mac’s footsteps – with upgraded 5nm chips in 2022 and new 3nm ones in 2023.
