Answer 1

ELI5 answer:

x86 is 32 bit CPU, and x64 is 64 bit CPU

More bits isn’t always better; it depends on what you’re doing. Think of it like using a cup vs a bucket. Cups are better for drinking, but buckets are better for moving large volumes of water.

ARM can be 32 or 64 bits, and it’s like CPU-lite. Less functionality, less energy, less heat, better for mobile devices.
