The 7 Levels of How a CPU Works

How does a CPU actually work?

In this video, we break down 7 levels of CPU understanding — from tiny transistors flipping on and off, all the way to modern multi-core, pipelined system-on-chip monsters like Apple’s M1.

You’ll learn:

👉 How transistors & logic gates form the basic building blocks

👉 What the ALU really does (and why it’s just a tool)

👉 Why registers, cache, and RAM are like a memory pyramid

👉 How instructions & programs turn simple operations into apps

👉 The fetch–decode–execute cycle that runs billions of times per second

👉 How pipelining & multiple cores massively boost performance

👉 And finally, CPU architecture & SoC design at the highest level
