how does a cpu convert virtually 100% of energy to heat when it uses energy to do calculations?

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.

I look at it the same way you would look at an air conditioner. All it is doing is moving heat- by the mechanism of evaporation and condensation. The energy used by the air conditioner is purely utilitarian work; its job isn’t to create heat, but rather it’s what’s expelled as the device operates.
Similarly, a cpu MOVES data- which happens to be in the form of electricity- by the same concept. It consumes energy by manipulating those electrical charges inside the computer. The fact that those electrical charges are the same kind of energy as what powers the CPU is incidental.
