What the article says around this equation
The roofline model’s ridge point, = / , says whether a kernel’s arithmetic intensity is high enough that memory bandwidth is not the binding constraint [ 7 ] . It says nothing about whether the array can actually deliver once that bar is cleared, because itself assumes every cell is doing useful work on every cycle — and a real systolic pipeline spends some of its cycles filling and draining rather than computing.
