From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For more power savings, you can undervolt your CPU if it supports it. On some CPUs, it can result in significant power savings.
Undervolting requires a lot of testing to make sure each core is stable under all conditions. There is no guarantee that a CPU will undervolt well though. Two identical CPUs can have significantly different results.
undervolting can also improve performance, depending on boost behaviour. it feels like you got a better binned chip.
I don't see how undervolting would result in power savings on modern CPUs if you're not up against clock limits as the CPU would simply boost higher.
