To be slightly pedantic here: Power is energy per second, so power consumption itself would go down. Total energy consumption, which is power*time could go up.

- morelisp 7y agoThe correction is welcome - I am just a little sad we trained a cohort of developers to care about power, but not well enough to understand that race-to-sleep is usually the best way to achieve that.
- marcosdumay 7y agoHum... Race to sleep is usually not the best way to save power. Undervoltage is. Race to sleep just gets the spotlight once you have an extremely optimized CPU that can not be undervolted anymore in a practical way. The rule of thumb you learned is useful for optimizing PC software, but has no place in CPU architecture discussions. Also, "usually" leaves a lot of important cases out.
