The "M-series" refers to a line of high-performance processors developed by Apple. These chips are designed for use in Mac computers and iPad devices, offering improved speed and efficiency compared to previous Intel-based models. The M-series utilizes a unified memory architecture, allowing for faster data access and better multitasking capabilities. The first chip in the M-series, the M1, was introduced in November 2020, followed by the M1 Pro, M1 Max, and M2 in subsequent years. Each iteration brings enhancements in processing power, graphics performance, and energy efficiency, making them suitable for demanding tasks like video editing and software development.
