Can I run Qwen3 1.7B on 16GB RAM Laptop (CPU/iGPU only)?

Compatibility verdict VRAM threshold engine
Yes, it runs usable speed ~35 tok/s est.

Yes. Qwen3 1.7B runs on 16GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~2.4 GB of ~12 GB usable).

Needs ~2.4 GB Device usable ~12 GB

Runs at Q4_K_M using ~2.4 GB of ~12 GB usable. You have room for FP16 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. 16GB RAM Laptop (CPU/iGPU only) leaves ~9.6 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

Power & economics est.
Power draw
~28 W
Electricity / 1M tokens
~$0.03
Pays for itself after
~1,596M tok

At ~$0.15/kWh and the estimated ~35 tok/s, a million generated tokens costs about $0.03 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$750 16GB RAM Laptop (CPU/iGPU only) pays for itself after roughly 1,596 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
