Can the RTX 3070 Ti Mobile run Qwen3-4B-Instruct-2507?
Yes. Qwen3-4B-Instruct-2507 fits the RTX 3070 Ti Mobile's 8 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 128 tok/s. There's room for up to Q8_0 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 2 GB | 3.8 GB | Fits easily | ~128 tok/s |
| Q5_K_M | 3 GB | 4.8 GB | Fits easily | ~86 tok/s |
| Q8_0 | 4 GB | 5.8 GB | Fits | ~64 tok/s |
| FP16 | 8 GB | 9.8 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 3070 Ti Mobile's 448 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 3070 Ti Mobile run Qwen3-4B-Instruct-2507?
Yes. Qwen3-4B-Instruct-2507 fits the RTX 3070 Ti Mobile's 8 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 128 tok/s. There's room for up to Q8_0 if you want higher quality.
How much VRAM does Qwen3-4B-Instruct-2507 need?
About 2 GB of weights at Q4_K_M, 4 GB at Q8_0 and 8 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3-4B-Instruct-2507 on the RTX 3070 Ti Mobile?
Roughly 128 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 3070 Ti Mobile's 448 GB/s memory bandwidth.
