Qwen3.5 9B needs ~6.4 GB VRAM. GTX 1060 6GB has 6.0 GB. With Q2_K quantization, expect ~18 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.

Offload
30%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.2 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, GTX 1060 6GB can run Qwen3.5 9B at Q2_K quantization (Runs with offload (needs ~0.2 GB host RAM)). The recommended Q4_K_M requires 8.3 GB which exceeds available memory, but at Q2_K it needs only 6.4 GB. Expected decode speed: 17.6 tok/s.
Qwen3.5 9B (9B parameters) requires approximately 8.3 GB at Q4_K_M quantization. On GTX 1060 6GB, it fits at Q2_K using 6.4 GB.
The recommended quantization is Q4_K_M, but on GTX 1060 6GB the best fitting quantization is Q2_K, which uses 6.4 GB.
On GTX 1060 6GB, Qwen3.5 9B achieves approximately 17.6 tokens per second decode speed with a time-to-first-token of 11014ms using Q2_K quantization.
For coding workloads, Qwen3.5 9B on GTX 1060 6GB receives a F grade with 7.3 tok/s and 4K context.
On GTX 1060 6GB, Qwen3.5 9B can safely use up to 10K tokens of context at Q2_K quantization. The model's official context limit is —, but available memory constrains the safe maximum.
