What is an ARM processor and how does it differ from x86?

Question

Accepted Answer

ARM processors use a reduced instruction set (RISC) architecture that prioritizes power efficiency, while x86 processors use a complex instruction set (CISC) optimized for raw performance. ARM dominates mobile devices and is rapidly expanding into laptops and servers — Apple Silicon and AWS Graviton proved ARM can compete with x86 on performance while using significantly less power.
