figure of merit
quantity used to characterize performance
utilization factor
ratio of the time that a piece of equipment is in use to the total time that it could be in use
instructions per second
measure of a computer's processing speed
Fusion energy gain factor
Ratio of fusion power produced in a fusion reactor to the power needed to keep it running
coefficient of performance
ratio of useful heating or cooling provided to work required
clock rate
frequency at which CPU chip or core is operating
power usage effectiveness
indicator: ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead)
performance per watt
type of figure of merit describing computer energy efficiency
Shock factor
figure of merit for the amount of shock by a naval target from an underwater explosion
