How the NVIDIA RTX 5070 Ti compares with similar cards

Compared with the NVIDIA RTX 5080, the NVIDIA RTX 5070 Ti has the same 16 GB of VRAM, so the same models fit fully on the GPU; about 7% slower token generation (~149 vs ~160 tokens/s on an 8B model in Q4, from 896 vs 960 GB/s) and a lower board power (300 vs 400 W). Side-by-side comparison
Compared with the NVIDIA RTX 4080 Super, the NVIDIA RTX 5070 Ti has the same 16 GB of VRAM, so the same models fit fully on the GPU; about 22% faster token generation (~149 vs ~123 tokens/s on an 8B model in Q4, from 896 vs 736 GB/s); a lower board power (300 vs 320 W) and a newer architecture (Blackwell vs Ada Lovelace). Side-by-side comparison
Compared with the NVIDIA RTX 4080, the NVIDIA RTX 5070 Ti has the same 16 GB of VRAM, so the same models fit fully on the GPU; about 25% faster token generation (~149 vs ~120 tokens/s on an 8B model in Q4, from 896 vs 717 GB/s); a lower board power (300 vs 320 W) and a newer architecture (Blackwell vs Ada Lovelace). Side-by-side comparison

Token speeds here are a conservative estimate (memory bandwidth ÷ 6, for an 8B model in Q4 that reads about 5 GB of weights per token, plus overhead); prompt processing depends on GPU compute instead.

Frequently asked questions

What is the VRAM and memory bandwidth of the NVIDIA RTX 5070 Ti?

The NVIDIA RTX 5070 Ti features 16 GB of VRAM and a memory bandwidth of 896 GB/s (GDDR7 256-bit). In local language model inference, VRAM determines which model sizes fit on the card, while memory bandwidth dictates how many tokens per second the GPU generates.

What is the best local AI model to run on a NVIDIA RTX 5070 Ti?

The best overall model for the NVIDIA RTX 5070 Ti is Qwen/Qwen3-8B-GGUF using the recommended Q8_0 quantization (9.47 GB total memory). With 16 GB of VRAM, this GPU typically runs a 14B at high quality, or a 24–27B at 4-bit at full GPU speed. Check our guide to the best LLMs for 16 GB VRAM for details.

Can the NVIDIA RTX 5070 Ti run 14B and 32B models?

Yes. A 16 GB VRAM buffer allows you to run 14B models (like Qwen 2.5 14B or DeepSeek-R1 14B) in high-fidelity Q8_0 quantizations, or 32B models (like Qwen 2.5 32B) in Q3_K_M or Q4_K_M quantizations fully on the GPU.

What power supply (PSU) do you need for the NVIDIA RTX 5070 Ti when running local AI?

The NVIDIA RTX 5070 Ti has a rated TDP of 300W. While local inference typically draws less power than full 3D rasterization or gaming, continuous token generation can sustain high loads. A quality power supply of at least 600W is strongly recommended.
