Why do CPUs and GPUs run hotter when doing more intensive tasks?
In your last statement I could see it making sense where the CPU actually halts, but did prior CPUs always run at about the same temperature? Or do these idle processes throw fewer instructions at one time so it's not as overwhelmed?
- semi-extrinsic 10y ago> did prior CPUs always run at about the same temperature? Basically, yes. But then they typically produced so little heat they had passive heatsinks, up to and including the Pentium II (~20 W TDP) and ATI Rage 128 that I used back in '99.
- caf 10y agoModern CPUs, GPUs and SOCs have power management states that disable entire submodules when they're not in use, by actually gating off the clock to them. If you run without power management enabled, you'll find that they run hot all the time.
