Can the RTX 4060 Mobile run Gemma 4 12B?
No. Gemma 4 12B needs about 8.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the RTX 4060 Mobile has 8 GB, so it won't fit without offloading layers to system RAM, which is far slower.
Every quantization
Gemma 4 12B (12B) on 8 GB
| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 7 GB | 8.8 GB | Too big | - |
| Q5_K_M | 9 GB | 10.8 GB | Too big | - |
| 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 4060 Mobile's 256 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the GeForce RTX 4060 Mobile run Gemma 4 12B?
No. Gemma 4 12B needs about 8.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the RTX 4060 Mobile has 8 GB, so it won't fit without offloading layers to system RAM, which is far slower.
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 4060 Mobile?
It doesn't fit in the RTX 4060 Mobile's memory, so speed depends on how many layers you offload to system RAM - typically single-digit tokens per second or lower.
