| Value kind | forecast — Forecasts are time-bound outlooks, not specifications; test decisions across plausible scenarios. |
|---|---|
| Caveat | NVIDIA targets H2 2027 for Rubin Ultra / Kyber; SemiAnalysis reported in July 2026 that it slips to 2028. The earlier points come from different OEM and reference-design profiles, so they do not trace one platform's progression. The 330 kW figure is the reference design's sizing basis, not a measured operating load. |
