Where the article explains it
with the peak arithmetic rate, B the achievable memory bandwidth and I the operational intensity of the kernel.
The passage around this formula
with the peak arithmetic rate, B the achievable memory bandwidth and I the operational intensity of the kernel. If I is small, the second term wins and the accelerator’s headline throughput is irrelevant.
