I have deliberately avoided all the "platorm security processor" infested stuff, meaning newer Intel and post 2013 AMD. For video editing the old AMD Bulldozer chips are surprisingly good peformers, though they are said to suck for single-threaded work. Under full load its a hot power hog but as soon as the render jobs are done it idles at maybe 2/3eds what the Phenom II was claimed to idle at.
Anyway, whatever the governors are called on a particular chip, the point is to be able to control them.
