CPU Power Management
Corey Gough, Ian M. Steiner, Winston A. Saunders · Apress eBooks · 2015
The CPUs and memory inside of a data center consume only a fraction of the overall power, but their efficiency and built-in power management capabilities are one of the biggest influences on overall data center efficiency. Saving power inside of the CPU has multiplicative savings at larger scales. Saving 1 watt of power at the CPU can easily turn into 1.5 watts of savings after power delivery efficiency losses inside the server, and up to 3 watts in the data center. Reducing CPU power reduces the cooling costs, since less heat must be removed from the overall system. These keywords were added by machine and not by the authors.
