Official CPU TDP values don't match real-life CPU heat output and power consumption. Real-life power usage found in professional CPU reviews is a much more reliable metric than official TDP values.
7. TDP (Thermal Design Power) Generally, lower CPU power consumption corresponds to less heat generation and better energy efficiency. TDP stands for "Thermal Design Power" and reflects the maximum ...
a CPU may have a fixed minimum power consumption and a variable consumption dependent on dynamic traffic load. Secondly, by varying the number of active resources on a granular basis – for ...
