CPU Throttling - definition

CPU Throttling is one of the most used items in CPU/GPU. We often see this term while gaming or talking about the peak performance of a device. It is also known as Thermal Throttling or Dynamic Frequency Scaling.

Basically, it is a power management technique in computer architecture where the frequency or clock speed can be automatically controlled based on the actual need, to continue processing when the heat gets generated during execution. Dynamic frequency scaling helps a device to provide the actual power needed in a specific moment by varying the clock speed.

i.e.: If a device is running a high-performance game that uses most of the CPU power and almost all possible cores then due to higher current flow inside the CPU cores it'll radiate more heat and cool it down we have cooling devices on desktop or laptop computer but in mobile devices, so what it does, it reduces the clock speed or the dynamic frequency for which the entire process of the system gets little slower then the average and it'll keep the state until the cores cool down properly and be ready to operate once again at full power and it'll keep happening unless or until the program is stopped completely.
