Dynamic 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.

What is dynamic voltage frequency scaling?

Dynamic voltage and frequency scaling (DVFS) is a technique that aims at reducing the dynamic power consumption by dynamically adjusting voltage and frequency of a CPU [33]. ... These frequency/voltage settings depend on the CPU and it is common to have ten or less clock frequencies available as operating points.

How is frequency scaling done?

In computer architecture, frequency scaling (also known as frequency ramping) is the technique of increasing a processor's frequency so as to enhance the performance of the system containing the processor in question. ... Increases in frequency thus increase the amount of power used in a processor.
