It combines four performance cores and four efficiency cores that work together to tackle demanding multi-threaded tasks, resulting in a quantum leap in performance at a fraction of the power - and a significant boost to battery life.įour performance cores Our high-performance core is the world’s fastest CPU core when it comes to low-power silicon 3 - and M1 has four of them combining their efforts for a massive boost in performance. 8-core CPU The 8-core CPU in M1 is the highest-performing CPU we’ve ever built, by far.
