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.

On modern CPUs they’re designed to “race to idle”. Consequently when they’re not idle they’re not very efficient. The biggest change that improves my battery life is adjusting how I do certain things. Instead of trying to slow things down even more to save power I just try to get them to finish quicker so my CPU can get back to idle (and efficient) faster.
Intel is really awful with this. AMD is better but slowly getting to Intel levels. E cores might change things up a bit, but I don’t have experience with them yet.
I don't follow, I thought AMD was less efficient. You say it's the other way around but it's getting worse? Or I'm reading it wrong?
AMD has been far more efficient at load for years
Hasn't been the case since Zen launched in 2017.
Although it took them 2-3 more years on laptop to overtake intel in efficiency, because of less sophisticated sleep stuff.
