M1 also features our unified memory architecture, or UMA. It’s also the first personal computer chip built using industry‑leading 5‑nanometre process technology. And with incredibly small transistors measured at an atomic scale, M1 is remarkably complex - packing the largest number of transistors we’ve ever put into a single chip. With M1, these technologies are combined into a single system on a chip (SoC), delivering a new level of integration for more simplicity, more efficiency and amazing performance.

Until now, a Mac needed multiple chips to deliver all of its features - including the processor, I/O, security and memory. The result is the best battery life ever on a Mac. macOS Big Sur features advanced power management that intelligently allocates tasks between the M1 performance and efficiency cores - automatically optimising for lightweight tasks like reading a note or performance‑intensive tasks like playing the latest game. But the chip itself is only part of this incredible power efficiency story. M1 extends battery life even while bringing a massive increase in performance. And your hardest-working apps all have access to the power they need. Everyday tasks from flipping through photos to browsing Safari are faster. The M1 chip and macOS Big Sur work together to make the entire system snappier. Altogether, you’ll have access to the biggest collection of apps ever for Mac. And for the first time, you can use your favourite iPhone and iPad apps directly on macOS Big Sur. All your existing apps work thanks to Rosetta 2. With incredible performance, custom technologies and industry-leading power efficiency,2 M1 is not just a next step for Mac - it’s another level entirely. Packed with an astonishing 16 billion transistors, the Apple M1 system on a chip (SoC) integrates the CPU, GPU, Neural Engine, I/O and so much more onto a single tiny chip. Our first chip designed specifically for Mac. This much power has never been this ready to go. The longest battery life ever in a MacBook Air. Our most advanced Neural Engine for up to 9x faster machine learning. Our thinnest, lightest notebook, completely transformed by the Apple M1 chip.
