Only just. Gemma 3 27B fits on the NVIDIA RTX 4070 Ti at Q2_K, which costs noticeable quality. Expect about 29 tokens/second. A card with more memory is a better experience.

Try other context lengths

Run it with Ollama

Ollama's default gemma3:27b download is Q4_K_M, which needs about 18.3 GB, more than the 12 GB available. Download the Q2_K GGUF instead (LM Studio lists quants per model), or try a smaller context length.
