Can I run Gemma 4 31B on Nvidia GeForce RTX 5090 (32GB)?
Yes. Gemma 4 31B runs on Nvidia GeForce RTX 5090 (32GB) at Q4_K_M (~20.5 GB of ~31 GB usable).
Runs at Q4_K_M using ~20.5 GB of ~31 GB usable.
That figure is at a 4k context and moves about ±15% as context length changes. Nvidia GeForce RTX 5090 (32GB) leaves ~10.5 GB of headroom.

- ~15,377M tok
At ~$0.15/kWh and the estimated ~64 tok/s, a million generated tokens costs about $0.37 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,999 Nvidia GeForce RTX 5090 (32GB) pays for itself after roughly 15,377 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.

FAQ
Can Nvidia GeForce RTX 5090 (32GB) run Gemma 4 31B?
Yes. Gemma 4 31B runs on Nvidia GeForce RTX 5090 (32GB) at Q4_K_M (~20.5 GB of ~31 GB usable).
How much memory does Gemma 4 31B need?
Nvidia GeForce RTX 5090 (32GB) has room to spare. At Q4_K_M the weights are ~18.32 GB; with KV cache and runtime overhead, budget ~20.5 GB at a 4k context.
What is the best tool to run Gemma 4 31B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

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.
