The dynamic power ( switching power) dissipated per unit of time by a chip is C See also: Processor power dissipation § Sources Automatic overclocking (boosting) is also technically a form of dynamic frequency scaling, but it's relatively new and usually not discussed with throttling. Processor throttling is also known as "automatic underclocking". The combined topic is known as dynamic voltage and frequency scaling ( DVFS). after poor overclocking).ĭynamic frequency scaling almost always appear in conjunction with dynamic voltage scaling, since lower frequencies require lower voltages for the digital circuit to yield correct results. Dynamic frequency scaling helps preserve battery on mobile devices and decrease cooling cost and noise on quiet computing settings, or can be useful as a security measure for overheated systems (e.g. JSTOR ( September 2021) ( Learn how and when to remove this template message)ĭynamic frequency scaling (also known as CPU throttling) is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to conserve power and reduce the amount of heat generated by the chip.Unsourced material may be challenged and removed.įind sources: "Dynamic frequency scaling" – news Please help improve this article by adding citations to reliable sources.
