power efficiency
Output per watt
Power efficiency measures how much useful output a system produces relative to the energy it consumes.
A power-efficient device wastes less energy as heat or noise: The new chips improved power efficiency by forty percent.
In electronics, this often means accomplishing the same task with fewer watts.
The term appears frequently in discussions of batteries, processors, and appliances where energy conservation matters.
