Where the article explains it
On a device it is primarily a bandwidth and energy intervention : halving the bits per weight halves W in the bound above and halves the bytes crossing the most energy-expensive interface in the system.
The passage around this formula
…and showed how latency, throughput and cost trade off under different sharding strategies, with generation and prefill behaving as different regimes [ 3 ] . The bound that matters on a device follows immediately: if W bytes of weights and cache must cross the memory bus for each token and the sustained bandwidth is B , then the time per token cannot be less than
