Can the RTX 5070 Mobile run Qwen3.5 9B?
Just. Qwen3.5 9B at Q4_K_M needs about 7.8 GB of the RTX 5070 Mobile's 8 GB, running at an estimated 37 tok/s. Keep context short and close other GPU apps.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 6 GB | 7.8 GB | Tight | ~37 tok/s |
| Q5_K_M | 7 GB | 8.8 GB | Too big | - |
| Q8_0 | 10 GB | 11.8 GB | Too big | - |
| 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 Mobile's 384 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 Mobile run Qwen3.5 9B?
Just. Qwen3.5 9B at Q4_K_M needs about 7.8 GB of the RTX 5070 Mobile's 8 GB, running at an estimated 37 tok/s. Keep context short and close other GPU apps.
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 Mobile?
Roughly 37 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 5070 Mobile's 384 GB/s memory bandwidth.
