What the article says around this equation
where is the number of operations one inference requires. This is the arithmetic that determines whether a given model can run a given number of times on a given battery before it needs replacing or recharging, and it is why a headline TOPS figure on a datasheet, quoted without the power draw it was measured at, tells a reader almost nothing about whether a part is suitable for a battery-powered product.
