Can the RTX 3060 Ti GDDR6X run Qwen3.5 4B?
Yes. Qwen3.5 4B fits the RTX 3060 Ti GDDR6X's 8 GB at Q4_K_M (about 4.8 GB needed), running at an estimated 116 tok/s. There's room for up to Q8_0 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 3 GB | 4.8 GB | Fits easily | ~116 tok/s |
| Q5_K_M | 3 GB | 4.8 GB | Fits easily | ~116 tok/s |
| Q8_0 | 5 GB | 6.8 GB | Fits | ~70 tok/s |
| FP16 | 9 GB | 10.8 GB | Too big | - |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 3060 Ti GDDR6X's 608.3 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the GeForce RTX 3060 Ti GDDR6X run Qwen3.5 4B?
Yes. Qwen3.5 4B fits the RTX 3060 Ti GDDR6X's 8 GB at Q4_K_M (about 4.8 GB needed), running at an estimated 116 tok/s. There's room for up to Q8_0 if you want higher quality.
How much VRAM does Qwen3.5 4B need?
About 3 GB of weights at Q4_K_M, 5 GB at Q8_0 and 9 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3.5 4B on the RTX 3060 Ti GDDR6X?
Roughly 116 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 3060 Ti GDDR6X's 608.3 GB/s memory bandwidth.
