Can I Run Nemotron 70B on NVIDIA A100 80GB (PCIe)?
Written by Jakub Rusinowski · Last updated July 21, 2026
Yes, comfortably — Nemotron 70B Instruct at Q4_K_M needs 46.1 GB at 8K context (42.6 GB weights + 3.5 GB KV cache/overhead), leaving ~33.9 GB of the NVIDIA A100 80GB (PCIe)'s 80 GB, at ~26 tok/s (est.), with room for up to 64K context.

Assumes an 8K-token context with an f16 KV cache. 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 A100 80GB (PCIe): 8K 46.1 GB · 32K 54.2 GB · 125K 85.4 GB ✗. Past 125K it no longer fits 80 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Nemotron 70B Instruct on 256 GB of system RAM, CPU only: runs, but too slowly to be worth it.
