Can RTX 5060 Ti 16GB run Qwen3.5 9B?
Measured results for Qwen3.5 9B (9.65B dense) on RTX 5060 Ti 16GB, plus what fits and the commands to run it.
Short answer
Yes. Qwen3.5 9B Q8_0 fits fully on RTX 5060 Ti 16GB at 16k context, using 10.1 of 15.0 GB usable, and generates about 45.9 tokens/s in our own run. As the context fills it slows down: 43.3 tok/s with 16k tokens already in context (94% of the empty-context speed), measured. For Q8_0, our bandwidth-only estimate was ~26 tok/s against a measured median of ~46 (44% too pessimistic).
Measured generation speed by quantization
| Quant | Generation tok/s | Range | Prompt tok/s | Runs | Origin |
|---|---|---|---|---|---|
| Q4 class (median) | 70 | 70–70 | 2955 | 1 | includes our runs |
| Q8 class (median) | 45.9 | 45.9–45.9 | 3078 | 1 | includes our runs |
| Q4_K_M (our run, depth 0) | 70 | 3 repeats | 2955 | 3 | own measurement |
| Q8_0 (our run, depth 0) | 45.9 | 3 repeats | 3078 | 3 | own measurement |
Generation = tg128 (128 generated tokens, short context). Public rows are medians of community llama.cpp results (sources); our own runs use llama-bench b11658 on a rented GPU.

FAQ
How fast is Qwen3.5 9B on RTX 5060 Ti 16GB?
About 45.9 tokens/s for generation (Q8_0 on llama.cpp CUDA, 128-token generation), 3078 tokens/s for prompt processing. Speed drops as the context fills; see the depth table.
How much memory does Qwen3.5 9B need on RTX 5060 Ti 16GB?
The advisor's pick, Q8_0, is 9.5 GB of weights plus 0.59 GB of KV cache at 16k context (10.1 GB), against 15.0 GB usable.
Is the Qwen3.5 9B speed on RTX 5060 Ti 16GB measured or estimated?
Measured: our own llama-bench run on a rented GeForce RTX 5060 Ti 16GB, including runs with 4k to 16k tokens already in context.
What can I use instead of RTX 5060 Ti 16GB for Qwen3.5 9B?
With less memory, 8GB VRAM class (RTX 4060 8GB, 32GB RAM) (~46 tok/s), Mac mini / iMac M4 16GB (~14 tok/s), RTX 5070 12GB (~68 tok/s) also fit it fully. Faster: RTX 5080 16GB (~92 tok/s), RTX 5070 Ti 16GB (~86 tok/s), RTX 4090 24GB (~95 tok/s).
What is the maximum context for Qwen3.5 9B on RTX 5060 Ti 16GB?
With an f16 KV cache about 128k tokens, 256k with q8_0 and 512k with q4_0, bounded by the model's own limit.
