Newer processors do the same amount of work faster using multiple cores, so they burn same amount of energy in shorter period of time.

- clinta 6y agoBut newer processors use less power at idle, and doing work faster means it can spend more time at that idle, low-power state.
- drran 6y agoYes, of course. Processors are idle most of the time anyway, but single processor has more time to dissipate heat passively doing same amount of work (e.g. 2% work, 98% idle), while multiple processors, e.g. 4, will use same amount of energy 4x faster (0.5% work, 99.5% idle), so fan will kick in.
