Throttling is a processor feature that helps reduce power consumption dynamically by adjusting the processor’s performance based on current workload and temperature conditions. When the CPU detects that it is running at high temperatures or that it is not being fully utilized, it can scale back its clock speed and voltage. This decrease in performance leads to lower power consumption and heat generation, which helps maintain system stability, prolong the life of the hardware, and improve overall energy efficiency.

This feature is especially useful in laptops and mobile devices where battery life is crucial. By implementing throttling, systems can effectively manage energy usage without the user having to make manual adjustments. In contrast, overclocking increases performance but can lead to higher power consumption, whereas caching improves data retrieval speeds without affecting power dynamics directly, and scheduling deals with task management rather than power reduction.
