Can H200 141GB SXM5 run Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16?
NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth ·
NVIDIA · 30.0B (active 3.0B) · MoE · model ctx up to 256K
Yes — the H200 141GB SXM5 (141 GB HBM3e) can run Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16. At Q4 with the default 8K context it needs ≈ 18.1 GB VRAM (weights 16.5 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 141 GB. Decode at Q4/8K: ≈ 1018.2 tok/s (estimated, batch 1). FP16 (≈ 61.6 GB) also fits, at ≈ 280.0 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
