Can I run Gemma 3 27B on Nvidia DGX Spark (128GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~11 tok/s est.

Yes. Gemma 3 27B runs on Nvidia DGX Spark (128GB) at Q4_K_M (~18.6 GB of ~112 GB usable).

Needs ~18.6 GB Device usable ~112 GB

Runs at Q4_K_M using ~18.6 GB of ~112 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. Nvidia DGX Spark (128GB) leaves ~93.4 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

Power & economics est.
Power draw
~140 W
Electricity / 1M tokens
~$0.53

At ~$0.15/kWh and the estimated ~11 tok/s, a million generated tokens costs about $0.53 in electricity. TDP is the peak draw, so this is an upper bound. Assumptions.
