Can I run Command R 35B on 32GB RAM Laptop (CPU/iGPU only)?

Compatibility verdict VRAM threshold engine

Yes, it runs slow on this hardware ~2 tok/s est.

Yes. Command R 35B runs on 32GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~22.3 GB of ~28 GB usable).

Needs ~22.3 GB Device usable ~28 GB

Runs at Q4_K_M using ~22.3 GB of ~28 GB usable.

That figure is at a 4k context and moves about ±15% as context length changes. 32GB RAM Laptop (CPU/iGPU only) leaves ~5.7 GB of headroom.

Running cost · estimate

Power & economics est.

Power draw: ~28 W
Electricity / 1M tokens: ~$0.58

At ~$0.15/kWh and the estimated ~2 tok/s, a million generated tokens costs about $0.58 in electricity. TDP is the peak draw, so this is an upper bound. Assumptions.
