Energy Efficiency And Speed Of CPU

[chewy0914]

I'm curious what happens to the energy that goes into a cpu?(gpu?)
Is it eventually grounded out? Does the electricity get reused? Same with a gpu?(ram/other)

If not currently reused would there be a reductions in cpu power use if it was?


I posted on blocks and vacuums in the power lines of motherboards/cpu's/other.
I'm curious if the build up points and vacuums were removed, or some type of vacuum was created to pull the electrons how fast could a cpu/gpu operate?
Speed of electrons/faster?

The energy powers the transistors (gates) and logic circuitry of the CPU and GPU. A great deal of the energy is converted to heat. THat's called "inefficiency" and is a major consideration in circuit design.

Vacuum does not operate on electrons - or at least now as you envisage. For all practical intents and purposes, the current flow in an integrated circuit operates at the speed of light. What controls it is the switching mechanism (clock) that determines when the various gates and junctions have to be sampled to determine their state. THat is the speed we commonly refer to in CPUs, eg. 3.4 GHz.

well..i like your question...
everything occurs due to electron movement.the work and the energy depend on that(that is E=qv,where E=energy,q=charge,v=potential difference)
during the movement of electron,it experiance some resistance. it causes energy loss in the form of heat.so the gpu/cpu get heated.
