Yes. Gemma 3 4B at Q8_0 needs about 6.3 GB, and the GeForce RTX 3070 Ti has 8.0 GB usable at a ~4k context.

Can I run Gemma 3 4B on an RTX 3070 Ti?

Gemma 3 4B at Q8_0 needs about 6.3 GB, and the GeForce RTX 3070 Ti has 8.0 GB usable. That figure is 8 GB of VRAM on the spec sheet, of which 8.0 GB is usable for weights and cache, at 608 GB/s memory bandwidth. Google’s small Gemma 3 instruct model, a good low-VRAM option with a different flavor from Llama 3.2 3B. These are estimates from our formula, not measured benchmarks.

Estimated tokens per second

Estimate: 80–113 tokens/sec at Q8_0. This is a bandwidth-derived range, not a bench. Efficiency is a 60–85% GPU band from How we calculate.

Context headroom

We do not have a published KV config for this model, so the memory need is the ~4k-context estimate only. Use the VRAM calculator to explore longer chats.
