The passage around this formula
…Using the whole-package figure as therefore overstates the copper baseline’s energy cost relative to memory bandwidth alone, which means it understates and, mechanically, would inflate any L computed against it. Even the “easy” side of this ratio is a biased proxy, not a clean measurement — and the bias runs in the direction that would make the optical case look better than it may actually be, which is exactly the wrong direction to lean on for a piece arguing that headline…
