|---|---|
| Scope | NVIDIA's July 2025 demonstration instrumented a GB200 rack carrying the new GB300 power shelf and ran a Megatron workload; it is not a comparison of a GB300 rack against a GB200 rack. One workload and one instrumented setup — qualify the installed load and smoothing controls at L4 rather than budgeting the reduction from a rack choice. |
