| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 6 GB | 7.8 GB | Fits | ~64 tok/s |
| Q5_K_M | 7 GB | 8.8 GB | Fits | ~55 tok/s |
| Q8_0 | 10 GB | 11.8 GB | Tight | ~39 tok/s |
| FP16 | 19 GB | 20.8 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 5070 Ti Mobile's 672 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 5070 Ti Mobile run Qwen3.5 9B?
Yes. Qwen3.5 9B fits the RTX 5070 Ti Mobile's 12 GB at Q4_K_M (about 7.8 GB needed), running at an estimated 64 tok/s. There's room for up to Q8_0 if you want higher quality.
How much VRAM does Qwen3.5 9B need?
About 6 GB of weights at Q4_K_M, 10 GB at Q8_0 and 19 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3.5 9B on the RTX 5070 Ti Mobile?
Roughly 64 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 5070 Ti Mobile's 672 GB/s memory bandwidth.
