Can I Run Qwen 3.5 on RTX 4060 Laptop (8 GB VRAM, 16 GB RAM)?

Written by Jakub Rusinowski · Last updated February 24, 2026

Yes, but it is tight

Yes, but it is tight — Qwen 3.5 9B at Q4_K_M needs about 7.4 GB of the 8 GB usable on RTX 4060 Laptop (8 GB VRAM, 16 GB RAM), leaving only ~0.6 GB before the runtime starts swapping. Expect ~31.4 tok/s (estimated), with room for about 8,192 tokens of context.

Confidence: low · Recommended quantization: Q4_K_M · Estimated speed: ~31.4 tok/s

What to watch out for

Only ~0.6 GB of headroom at Q4_K_M: a longer context or a second application can push this into swapping.
4 larger variants of Qwen 3.5 do not fit and would need CPU offload or different hardware.
This model does not publish its full attention configuration, so the KV-cache share of these figures is inferred from its parameter count rather than computed exactly.

RTX 4060 laptop limitations

8 GB VRAM limits you to 7–8B models at Q4 with a short context.
System RAM is usually upgradeable on this class of laptop even though VRAM is not.

Recommended setup

Ollama or llama.cpp (CUDA/ROCm) — vLLM if you need concurrent serving

How these numbers are calculated

Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
8 GB of VRAM on the NVIDIA GeForce RTX 4060 at 272 GB/s.
16 GB of system RAM available for CPU offload when a model exceeds VRAM.
Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
KV cache is inferred from the parameter count because this model does not publish its full attention configuration.
