Can I Run Nemotron 3 Super on NVIDIA H100 80GB (PCIe)?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 15 sierpnia 2026
Yes, but it's tight — Nemotron 3 Super 120B-A12B at Q4_K_M needs 76.1 GB at 8K context (72.5 GB weights + 3.6 GB KV cache/overhead), leaving ~3.9 GB of the NVIDIA H100 80GB (PCIe)'s 80 GB, at ~136 tok/s (est.), with room for up to 16K context.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 80 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA H100 80GB (PCIe): 8K 76.1 GB · 32K 84.7 GB ✗ · 128K 118.9 GB ✗. Past 32K it no longer fits 80 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
