Can I Run Llama 3.2 1B Instruct on NVIDIA H100 80GB (PCIe)?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 21 lipca 2026
Yes. Llama 3.2 1B Instruct needs 1.8 GB at 8K context (0.7 GB weights + 1.1 GB KV cache/overhead) at Q4_K_M and the NVIDIA H100 80GB (PCIe) has 80 GB, leaving about 78.2 GB of headroom, at roughly 362 tok/s (estimated) with room for up to 64K of context.

Llama 3.2 1B Instruct on the NVIDIA H100 80GB (PCIe): VRAM by quantization
| Quant | VRAM needed | Fits 80 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 3.5 GB | ✓ Yes | 64K | — |
| Q8_0 | 2.4 GB | ✓ Yes | 64K | — |
| Q6_K | 2.1 GB | ✓ Yes | 64K | — |
| Q5_K_M | 1.9 GB | ✓ Yes | 64K | — |
| Q4_K_M | 1.8 GB | ✓ Yes | 64K | — |

| Q2_K | 1.5 GB | ✓ Yes | 64K | — |
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 H100 80GB (PCIe): 8K 1.8 GB · 32K 2.6 GB · 125K 5.7 GB. Every window this model publishes still fits 80 GB.
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.
