Where the article explains it

” Neither $P_{\text{active}}$ nor $t_{\text{active}}$ is fixed by the model architecture alone; both depend on the accelerator the model runs on.

The passage around this formula

This identity is trivial algebraically, but it is exactly the trade a systems designer is making when choosing between “a bigger, slower model that runs less often” and “a smaller, faster model that still meets the same detection latency.” Neither $P_{\text{active}}$ nor $t_{\text{active}}$ is fixed by the model architecture alone; both depend on the accelerator the model runs on.
