Can I run Gemma 2 9B on 8GB RAM Laptop (CPU/iGPU only)?

Compatibility verdict VRAM threshold engine
No, not enough memory would not load

No. Gemma 2 9B needs ~7.3 GB even at Q4_K_M, but 8GB RAM Laptop (CPU/iGPU only) only has ~5 GB usable.

Needs ~7.3 GB Device usable ~5 GB

Needs ~7.3 GB even at Q4_K_M, but only ~5 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 2.3 GB: Gemma 2 9B needs roughly 7.3 GB at Q4_K_M and 8GB RAM Laptop (CPU/iGPU only) leaves only about 5 GB usable for a model. The lightest tracked hardware that runs Gemma 2 9B is the Nvidia GeForce RTX 3060 (12GB) at 12 GB. See Gemma 2 9B on Nvidia GeForce RTX 3060 (12GB).
