Inside a modern phone chip, explained

A modern phone chip is a tiny city. Billions of switches share one square the size of a fingernail, and each one has a job. In this guide we call the example chip Orbit-X, made by the invented firm Northlake Silicon, with about $n = 8$ cores¹.

Think of cores as workers, cache as a desk, and memory as a far-away cupboard. The closer the data, the faster the work.
