FAQ
Can the NVIDIA RTX 2080 Ti run Gemma 3 12B?
Yes. The NVIDIA RTX 2080 Ti's 11.0GB of VRAM is enough to run Gemma 3 12B at Q5_K_M quantization (9.7GB required).
What's the best quantization to use?
Q5_K_M is the highest-precision quantization that fits in your 11.0GB. It uses about 9.7GB of memory and 11.2GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
