For each model, the highest-precision quantization that runs entirely in fast memory; otherwise the one with the best result. Speeds are ranges; "estimate" unless a benchmark exists for this exact hardware.

Limits in plain words

12 GB of VRAM holds the weights and KV cache of models up to about Qwen3 14B at Q4_K_M. Bigger models spill into system RAM and slow down sharply: generation speed is then limited by RAM bandwidth, not by the GPU.

Frequently asked questions

Which LLMs can the RTX 4070 Ti run?
Entirely on the GPU: Qwen3 14B (Q4_K_M), DeepSeek R1 Distill Qwen 14B (IQ4_XS), Qwen2.5 14B Instruct (IQ4_XS), Phi-4 14B (IQ4_XS), Mistral Nemo 12B Instruct (Q5_K_M), Gemma 3 12B IT (Q5_K_M), Gemma 2 9B IT (Q6_K), Qwen3 8B (Q8_0). Larger models need CPU/GPU offload.
Can the RTX 4070 Ti run a 70B model?
Not recommended: a 70B model at Q4_K_M needs about 45.1 GB; the RTX 4070 Ti has 12 GB.
How is the speed estimated?
Token generation reads every active weight once per token, so it is limited by memory bandwidth (504 GB/s here). We apply an efficiency range per backend and label the result as an estimate until real benchmarks exist.
