Q: What quantization of Gemma 3 27B should I use on a NVIDIA GeForce RTX 5070 Ti?

For 16 GB VRAM on the NVIDIA GeForce RTX 5070 Ti, the Q8_0 variant is the best fit. Estimated ~9 tokens/sec on the Q8_0 quantization.

Q: How fast does Gemma 3 27B run on NVIDIA GeForce RTX 5070 Ti?

Roughly 9 tokens/sec for Q8_0. Real speed depends on context length, backend (Ollama, llama.cpp, LM Studio), and KV cache size.

Q: What if NVIDIA GeForce RTX 5070 Ti is not enough for Gemma 3 27B?

Consider upgrading to Apple M3 Pro (36 GB VRAM) which fits the recommended 36 GB target. Or pick a smaller quantization to stay on your current card.

Question 1

Can I run Gemma 3 27B on a NVIDIA GeForce RTX 5070 Ti?

Accepted Answer

Sort of — NVIDIA GeForce RTX 5070 Ti can run Gemma 3 27B (Q8_0) only by spilling layers to RAM. Generation will be slow. CPU + GPU hybrid — not enough VRAM (16 GB < 30 GB min), but 64 GB RAM is sufficient. Expect significantly slower inference.
