Can the RTX 5070 run Gemma 4 12B?
Yes. Gemma 4 12B fits the RTX 5070's 12 GB at Q4_K_M (about 8.8 GB needed), running at an estimated 55 tok/s. There's room for up to Q5_K_M if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 7 GB | 8.8 GB | Fits | ~55 tok/s |
| Q5_K_M | 9 GB | 10.8 GB | Tight | ~43 tok/s |
| Q8_0 | 13 GB | 14.8 GB | Too big | - |
| FP16 | 24 GB | 25.8 GB | Too big | - |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 5070's 672 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA RTX 5070 run Gemma 4 12B?
Yes. Gemma 4 12B fits the RTX 5070's 12 GB at Q4_K_M (about 8.8 GB needed), running at an estimated 55 tok/s. There's room for up to Q5_K_M if you want higher quality.
How much VRAM does Gemma 4 12B need?
About 7 GB of weights at Q4_K_M, 13 GB at Q8_0 and 24 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Gemma 4 12B on the RTX 5070?
Roughly 55 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 5070's 672 GB/s memory bandwidth.
