The new Macbook Air will feature the Apple M1 CPU, which is the latest in a line of higher-performance ARM CPUs introduced with the iPad Pro. M1 is a an 8-core CPU built on a 5nm process design, and features unified memory architecture, offering high-bandwidth low-latency memory access. Of its 8 cores, four are higher-performance aimed at demanding foreground tasks, and four are lower-power, higher-efficiency designed to complete less-demanding background tasks at a decreased power and thermal cost.
