TDP stands for Thermal Design Power, which is a specification measured in watts that tells us the maximum amount of heat generated by a computer chip or component that the cooling system in a computer is designed to dissipate under any workload. TDP is often used as a basic indicator of power consumption, and it is calculated according to the amount of power the computers fan and heatsink need to be able to dissipate while the chip is under sustained load. TDP is usually measured in watts and categorized into low-power, medium-power, and high-power. It is important to note that TDP is not a measure of the peak power consumption of the processor, but rather an upper bound on heat dissipation by the package when operating near its base frequency. TDP specifications for some processors may allow them to work under multiple different power levels, depending on the usage scenario, available cooling capacities, and desired power consumption. Technologies that provide such variable TDPs include Intels configurable TDP (cTDP) and scenario design power (SDP), and AMDs TDP power cap.
