Can I run Ministral 3 8B on 16GB RAM Laptop (CPU/iGPU only)?

Compatibility verdict VRAM threshold engine

Yes, it runs usable speed ~9 tok/s est.

Yes. Ministral 3 8B runs on 16GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~6.3 GB of ~12 GB usable).

Needs ~6.3 GB Device usable ~12 GB

Runs at Q4_K_M using ~6.3 GB of ~12 GB usable. You have room for Q8_0 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 ~5.7 GB of headroom, room to step up to Q8_0 for higher quality.

Running cost · estimate

Power & economics est.

Power draw: ~28 W
Electricity / 1M tokens: ~$0.13
Pays for itself after: ~2,027M tok

At ~$0.15/kWh and the estimated ~9 tok/s, a million generated tokens costs about $0.13 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 2,027 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.
