How the M1 Ultra paves the way for the next ‘Extreme’ Apple chip
When Apple released the M1 chip at the end of 2020, we were blown away by the speed improvements over its Intel predecessors. A year later Apple did it again with the M1 Pro and M1 Max, and then in March 2022, Apple revealed the M1 Ultra, filling out the M1 chip line-up and dramatically altering our expectations for Apple’s roadmap.
