After gating the clocks of every one of the cores, what other techniques can you use to get even more power savings. Here’s a trivial and admittedly flippant example of what you could do: unplug the processor. You’d be using no power, though the disadvantages of pulling the power plug are pretty obvious. A better idea is to selectively shutdown the more global components of the processor in such... Last updated on 09/06/2013 - 18:26

C-States, P-States, where the heck are those T-States?

Authored by Taylor Kidd (Intel)

I had an interesting question come across my desk a few days ago: “Is it still worthwhile to understand T-states?” My first response was to think, “Huh? What the heck is a T-state?”
