The passage around this formula
That is a clean, falsifiable test in principle. In practice, computing L for the Photonic Fabric Module runs into a wall immediately, and the wall is worth describing precisely rather than waved past. B is at least partially available — the module’s 7.2-terabit-per-second optical connectivity figure and the appliance’s 32-terabyte pooled capacity are both disclosed, even if the realized random-access figure specifically (as opposed to the module’s headline peak) is not. is not available at all. Not in the chiplet-marketplace technical summary, not in Celestial AI’s own Hot Chips 2025 presentation, not anywhere on the corporate site that now forwards to Marvell’s.…
