I'm curious about something. Does a processor use more power while its executing instructions than it does while idle? If its running at 50% CPU, does it use more power than at 0%, and less than at 100% busy?
Or, does it use the same power whether busy or idle.

On my home machine, which uses an AMD chip, I have a tray icon which shows CPU temp. I can watch the temperature rise when I run CPU-intensive loads and (more slowly) drop when those loads end.
