Compile in Xcode in significantly less time. This results in a quantum leap in performance - even while drawing much less power.įour performance cores Our high-performance core is the world’s fastest CPU core when it comes to low-power silicon 4 - and M1 has four of them, combining their efforts for a massive boost in performance. It combines four performance cores and four efficiency cores to deliver the world’s best CPU performance per watt 3 for both single-threaded and multithreaded tasks. 8-core CPU The 8-core CPU in M1 is the highest-performing CPU we’ve ever built, by far.
