CPO power efficiency gain vs pluggable optics (NVIDIA silicon photonics; ≈70% optical-interconnect power cut, Broadcom Davisson)
~3.5xobserved
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Caveat | Vendor comparisons on different measurement boundaries, not interchangeable installed-system guarantees: ~3.5× is NVIDIA's March 2025 silicon-photonics claim against pluggable optics; the ≈70% lower optical-interconnect power is Broadcom's separate October 2025 Davisson claim. |
