- In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. Performance (unlike watt) isn't an objective thing, it depends on what the computer is working on, but the Green500 list ranks the most efficient computers, according to one benchmark.
System designers building parallel computers, such as Google's hardware, pick CPUs based on their (other than Green500) performance per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. [1]
