Can I Run Qwen 3.5 4B on NVIDIA RTX 6000 Ada Generation?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 21 lipca 2026
Yes. Qwen 3.5 4B needs 3.5 GB at 8K context (2.4 GB weights + 1.1 GB KV cache/overhead) at Q4_K_M and the NVIDIA RTX 6000 Ada Generation has 48 GB, leaving about 44.5 GB of headroom, at roughly 196 tok/s (estimated) with room for up to 32K of context.

Qwen 3.5 4B on the NVIDIA RTX 6000 Ada Generation: VRAM by quantization
| Quant | VRAM needed | Fits 48 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 9.1 GB | ✓ Yes | 32K | — |
| Q8_0 | 5.3 GB | ✓ Yes | 32K | — |
| Q6_K | 4.3 GB | ✓ Yes | 32K | — |
| Q5_K_M | 3.9 GB | ✓ Yes | 32K | — |
| Q4_K_M | 3.5 GB | ✓ Yes | 32K | — |
| Q3_K_M | 2.8 GB | ✓ Yes | 32K | — |
| Q2_K | 2.4 GB | ✓ Yes | 32K | — |
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 RTX 6000 Ada Generation: 8K 3.5 GB · 32K 4.3 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.
