As expected, Apple today announced its first Arm-based laptops, the MacBook Air, Mac mini and Macbook Pro, and, with that, it also announced its family of Arm-based Apple Silicon chips. When it first announced Apple Silicon, the company didn’t provide a lot of details, but in today’s presentation, we learned quite a bit more. The first chip in this family is the M1, based on a 5nm process.

“We’ve been making Apple Silicon for more than a decade. It’s at the heart of iPhone, iPad, and Apple Watch – and now we want to bring it to the Mac, so the Mac can take a huge leap forward with the incredible performance, custom technologies and industry-leading power efficiency of Apple Silicon,” Apple said.
