Can H100 80GB SXM5 run NVIDIA-Nemotron-3-Super-120B-A12B-BF16?

NVIDIA · 80 GB HBM3 · 3350 GB/s bandwidth · NVIDIA · 120.0B (active 12.0B) · MoE · model ctx up to 256K

✅ Yes — H100 80GB SXM5 (80 GB) can run NVIDIA-Nemotron-3-Super-120B-A12B-BF16 at Q4 (8K)
VRAM: 67.12 GB needed of 80 GB
Speed: ~177.7 tok/s (estimated)
BB · GoodComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K context.
