Can I Run Llama 4 Scout 17B on NVIDIA A100 80GB (PCIe)?
作者： Jakub Rusinowski · 最后更新： 2026年7月21日
Yes. Llama 4 Scout 17B needs 68.2 GB at 8K context (65.8 GB weights + 2.4 GB KV cache/overhead) at Q4_K_M and the NVIDIA A100 80GB (PCIe) has 80 GB, leaving about 11.8 GB of headroom, at roughly 87 tok/s (estimated) with room for up to 64K of 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 68.2 GB · 32K 73.1 GB · 128K 92.4 GB ✗. Past 128K it no longer fits 80 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
