During the recent PC Perspective Podcast, you may have heard us mention the evolution of C-states in the CPU while we were discussing the Nehalem’s ability to shut off power to certain cores while cranking up the speed of those remaining powered.  If you were scratching your head about how that applied, or just need some reminding about what what each of states represents, drop by Hardware Secrets for a refresher.

“In order to save energy when the CPU is idle, the CPU can be commanded to enter a low-power mode. Each CPU has several power modes and they are collectively called “C-states” or “C-modes”. In this tutorial we will explain what these modes are, what they do and the modes supported by each processor.”
