Qwen 2.5 VL 7B Instruct on the NVIDIA L40S: VRAM by quantization
| Quant | VRAM needed | Fits 48 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 17.8 GB | ✓ Yes | 64K | — |
| Q8_0 | 10.1 GB | ✓ Yes | 64K | — |
| Q6_K | 8.1 GB | ✓ Yes | 64K | — |
| Q5_K_M | 7.1 GB | ✓ Yes | 64K | — |
| Q4_K_M | 6.3 GB | ✓ Yes | 64K | — |
| Q3_K_M | 4.8 GB | ✓ Yes | 64K | — |
| Q2_K | 4 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 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 L40S: 8K 6.3 GB · 32K 7.7 GB · 125K 13.1 GB. Every window this model publishes still fits 48 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.
