Can I run Gemma 4 12B on AMD Radeon RX 7900 XTX (24GB)?
Yes. Gemma 4 12B runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~8.7 GB of ~23 GB usable).
Runs at Q4_K_M using ~8.7 GB of ~23 GB usable. You have room for Q8_0 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. AMD Radeon RX 7900 XTX (24GB) leaves ~14.3 GB of headroom, room to step up to Q8_0 for higher quality.

Running cost · estimate

- Electricity / 1M tokens

- Pays for itself after
- ~3,027M tok
At ~$0.15/kWh and the estimated ~88 tok/s, a million generated tokens costs about $0.17 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$999 AMD Radeon RX 7900 XTX (24GB) pays for itself after roughly 3,027 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 AMD Radeon RX 7900 XTX (24GB) run Gemma 4 12B?
Yes. Gemma 4 12B runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~8.7 GB of ~23 GB usable).
How much memory does Gemma 4 12B need?
AMD Radeon RX 7900 XTX (24GB) has room to spare. At Q4_K_M the weights are ~7.12 GB; with KV cache and runtime overhead, budget ~8.7 GB at a 4k context.
What is the best tool to run Gemma 4 12B 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.
