Throttling is a term used to describe the act of down-clocking an integrated circuit to decrease power usage, heat generation, or both. The typical symptom people notice is a drastic reduction in game performance, and the typical reason for throttling is a lack of sufficient cooling of the chip being throttled, whether it be...
