Can I run Gemma 3 4B on Nvidia GeForce RTX 4070 (12GB)?
Yes. Gemma 3 4B runs on Nvidia GeForce RTX 4070 (12GB) at Q4_K_M (~3.8 GB of ~11 GB usable).
Runs at Q4_K_M using ~3.8 GB of ~11 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 GeForce RTX 4070 (12GB) leaves ~7.2 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

- Electricity / 1M tokens

- Pays for itself after
- ~1,361M tok
At ~$0.15/kWh and the estimated ~132 tok/s, a million generated tokens costs about $0.06 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$599 Nvidia GeForce RTX 4070 (12GB) pays for itself after roughly 1,361 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 4070 (12GB) run Gemma 3 4B?
Yes. Gemma 3 4B runs on Nvidia GeForce RTX 4070 (12GB) at Q4_K_M (~3.8 GB of ~11 GB usable).
How much memory does Gemma 3 4B need?
Nvidia GeForce RTX 4070 (12GB) has room to spare. At Q4_K_M the weights are ~2.49 GB; with KV cache and runtime overhead, budget ~3.8 GB at a 4k context.
What is the best tool to run Gemma 3 4B 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.
