The passage around this formula
TOPS , tera-operations per second, measures raw throughput: how many multiply-accumulate operations a chip can, in principle, perform in a second. It says nothing about power, and by itself it is close to useless for comparing edge hardware, because a processor is free to spend arbitrarily large power to hit a large TOPS number. The metric that actually matters for a battery-powered or thermally constrained device is efficiency — operations delivered per unit of energy, conventionally reported as TOPS per watt : . Because a watt is a joule per second, measured this way is numerically the same quantity as operations delivered per joule. That equivalence matters because…
Learn the underlying idea
A fraction a/b means a divided by b. The top number is the numerator; the bottom number is the denominator, and it cannot be zero.
