  • Publication number: 20220147127
    Abstract: Techniques for allocating power budget to a central processing unit (CPU) of a computing device are described. According to an example of the present subject matter, a CPU is operated at default power level corresponding to a thermal design power (TDP) of the computing device. Thereafter, an unused power of the computing device is determined at run-time. The unused power is a difference between an allocated power budget of the component and current power consumption of the component, wherein the allocated power budget is an amount of power allocated to the component based on the TDP of the computing device. Based on the unused power the CPU is operated at a high-performance power level. The high-performance power level is a power level above the default power and up to a maximum power level of the CPU.
