vendor-reported conductor comparison for a stated 415 VAC → 800 VDC topology and loss basis
157% / ~61%observed
| 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. |

| Scope | Topology-, conductor-count-, route-, temperature- and loss-basis-specific; recompute for the project one-line. |
| Caveat | NVIDIA (2025-10-13): 800 VDC carries 157% more power than 415 VAC at the same wire gauge. The reciprocal copper saving is ~61% for equal power, not the ~45% previously paired with an ~85% figure from an earlier NVIDIA basis. Both are topology-specific vendor comparisons, not constants — compute your own from conductor count and route. |
