I=WQI = \frac{W}{Q}

Why this formula appears here

Define arithmetic intensity I as the ratio of arithmetic operations performed to bytes moved between the accelerator and its off-chip memory: I=WQI = \frac{W}{Q}. with W operations and Q bytes. Let Pmax⁡P_{\max} be the machine’s peak arithmetic rate and β\beta its achievable memory bandwidth. Then attainable performance is bounded by
