I’m confused. I did some research online, and learned that cpu’s can essentially double has a hotplate, because 99-100% of electricity consumed is turned into heat. how? doesn’t the cpu use energy to make calcuations and render things? I’m real confused.

Answer 1

The calculations are done by turning electricity into heat in various different ways.

Or to put it another way, an electric hotplate has exactly one way of turning electricity into heat. A CPU has many ways to turn electricity into heat.
