Can I Run Nemotron 3 Super on NVIDIA RTX 6000 Ada Generation?
Written by Jakub Rusinowski · Last updated August 15, 2026
No — 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), and the NVIDIA RTX 6000 Ada Generation's 48 GB leaves it ~28.1 GB short. The cheapest card that runs it is the NVIDIA A100 80GB (PCIe) (80 GB).

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 48 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 RTX 6000 Ada Generation: 8K 76.1 GB ✗ · 32K 84.7 GB ✗ · 128K 118.9 GB ✗. Past 8K it no longer fits 48 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
