Can you run Qwen3.5 9B Instruct (Q8) on RTX 3060?
Qwen3.5 9B Instruct (Q8) Q8_0 on the NVIDIA GeForce RTX 3060: verdict, VRAM math and estimated speed.
Yes, the NVIDIA GeForce RTX 3060 runs Qwen3.5 9B Instruct (Q8). 10.7 GB weights at Q8_0 vs 10.8 GB usable VRAM; ~24 tok/s est. (ModelFit, 2026).
VRAM math and speed are ModelFit engine estimates, not measurements. Commands are registry-verified Ollama tags.

What limits this combo
The four constraints the fit engine checks for Qwen3.5 9B Instruct (Q8) on the RTX 3060, in order of what usually breaks first.
Where the RTX 3060 sits for Qwen3.5 9B Instruct (Q8)
The RTX 3060 is the cheapest tracked card that runs Qwen3.5 9B Instruct (Q8) fully in VRAM (~24 tok/s est.). Every cheaper card in the table forces partial offload. The next step up, the RTX 4060 Ti, reaches ~19 tok/s est. with a 64k context ceiling.
Same engine as the verdict above: 90% of VRAM usable, KV-cache at fp16, bandwidth-derived tok/s. Verdicts of the other cards are computed for Qwen3.5 9B Instruct (Q8) Q8_0 exactly.
Quant explorer
Switch between the quality-gated builds tracked for this exact combo. Q4_K_M stays the default recommendation; heavier Q6/Q8 builds only appear when their exact Ollama tags are registry-verified.
Why no 2-bit builds: Q1/Q2-class quants can look attractive in a memory table, but their quality loss is large enough that ModelFit excludes them from rankings instead of inflating the catalog with junk options. Usable VRAM: 10.8 GB.
Workload verdicts
Qwen3.5 9B Instruct (Q8) on the RTX 3060, graded per use case from the model's registry-verified tuning and the engine's speed estimate for this exact combo.
Grades combine tag-verified tuning (a model not built for the workload caps at C) with the tok/s floor each workload needs to feel usable. A combo that partially offloads caps at C; one that does not fit is D everywhere.
Memory math: weights + context vs budget
Weights take 10.7 GB. Context costs extra KV-cache on top; this is where long-context sessions break on cards that technically fit the weights.
This configuration exceeds the comfortable VRAM budget by about 0.4 GB. Expect offload pressure or a shorter safe context.
KV-cache figures assume an fp16 cache, the llama.cpp/Ollama default. Standard GQA models use a size-class estimate (8 KV heads x 128 head dim class); hybrid linear-attention models (Qwen3.5/3.6, Qwen3-Next) use the exact per-token cost from their published config, since only their sparse full-attention layers cache KV. A q8_0 KV cache roughly halves either figure. Estimates, not measurements.

Qwen3.5 9B Instruct (Q8) on RTX 3060: FAQ
Can the NVIDIA GeForce RTX 3060 run Qwen3.5 9B Instruct (Q8)?
Yes. Qwen3.5 9B Instruct (Q8) (Q8_0) loads in about 10.7 GB and the RTX 3060 offers 10.8 GB of usable VRAM, leaving headroom for context. Expect at roughly 24 tokens/sec (est.).
How much VRAM does Qwen3.5 9B Instruct (Q8) need?
About 10.7 GB for the weights at Q8_0, plus KV-cache for context: roughly 0.5 GB extra at 16k tokens. The RTX 3060 budget is 10.8 GB (12 GB x 90%).
What is the best quantization of Qwen3.5 9B Instruct (Q8) for the RTX 3060?
The Q4_K_M build is the highest quality that fits (7 GB vs 10.8 GB usable). The Q8_0 build at 10.7 GB leaves more room for long context.
What GPU do I need to run Qwen3.5 9B Instruct (Q8) comfortably?
The RTX 3060 already runs Qwen3.5 9B Instruct (Q8) comfortably. Larger cards only buy you longer context or a heavier quant.
How much context can Qwen3.5 9B Instruct (Q8) use on the RTX 3060?
None worth having: the 10.7 GB of weights alone exceed the 10.8 GB usable VRAM, so the model only runs with system-RAM offload and short prompts.
Is Qwen3.5 9B Instruct (Q8) on the RTX 3060 fast enough for coding agents?
No: the engine estimates ~24 tok/s against the ~30 tok/s an agentic loop needs to feel responsive. Chat will feel fine, but multi-step agent runs will drag; a smaller model or a bigger card is the fix.
