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

Question

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

All “energy used” is converted to heat. That is the end state for all energy.

If the CPU does X and draws Y watts of power to do it, X will happen and it will radiate Y watts worth of heat.
