Qwen 2.5 7B Instruct on the NVIDIA GeForce RTX 5090: VRAM by quantization
| Quant | VRAM needed | Fits 32 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 16.5 GB | ✓ Yes | 128K | — |
| Q8_0 | 9.3 GB | ✓ Yes | 128K | — |
| Q6_K | 7.5 GB | ✓ Yes | 128K | — |
| Q5_K_M | 6.7 GB | ✓ Yes | 128K | — |
| Q4_K_M | 5.9 GB | ✓ Yes | 128K | — |
| Q3_K_M | 4.5 GB | ✓ Yes | 128K | — |
| Q2_K | 3.8 GB | ✓ Yes | 128K | — |
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 32 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 GeForce RTX 5090: 8K 5.9 GB · 32K 7.3 GB · 128K 12.9 GB. Every window this model publishes still fits 32 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.
