This article, from 2014 demystifies a lot of power related concepts and nomenclature regarding Intel hardware. It’s useful for when you’re looking what specific BIOS settings really do (“Package C State Support” for instance) and explains other things you might have come across, e.g. when creating a custom Linux kernel, stuff like “uncore”.
So while it is not an article of the Breaking News kind, it was an interesting read with a lot of useful information. As such, I couldn’t resist sharing it with the risk of Lobsters.
