Its job in the formula

Approximately equal to; the equality is not exact.

The passage around this formula

read in full every step for every active request. Total bytes moved per step across a batch of b requests at sequence length s is therefore approximately B(b,s)≈Np+b Mkv(s)B(b,s) \approx Np + b\,M_{\mathrm{kv}}(s). and the achievable step rate is B divided into the device’s usable bandwidth. Two things follow immediately.
