RTX 4070 Ti Super 16GB for local AI
A fast 16 GB card. It runs 14B models at high quality and 24B models at Q4_K_M with a short context.
Setup tips: a strong 16 GB card for gpt-oss-20b, Gemma 4 26B-A4B and 14B models at high quality. 24B dense models fit at Q4_K_M only with a short context. It handles FLUX.1 in FP8 well thanks to Ada's FP8 support.
Among the 14 devices we track with about 16 GB of usable memory, the RTX 4070 Ti Super 16GB ranks 5 of 14 for text-generation speed, because generation speed follows memory bandwidth. Others in the same class: RTX 5080 16GB, RTX 5070 Ti 16GB, RTX 4080 Super 16GB, RTX 4080 16GB. They all hold the same models; the faster ones simply answer sooner.

Comparisons
RTX 4070 Ti Super 16GB for LLMs: common questions
Can the RTX 4070 Ti Super 16GB run Llama 3.3 70B?
Only partly. It needs about 43.2 GB at Q4_K_M, so about 35% fits in VRAM and the rest runs from system RAM, which is slow.
Can the RTX 4070 Ti Super 16GB run Qwen 3 32B?
Only partly. It needs about 21.4 GB at Q4_K_M, so about 70% fits in VRAM and the rest runs from system RAM, which is slow. Q2_K fits fully.
Can the RTX 4070 Ti Super 16GB run Qwen 3 14B?
Yes. Qwen 3 14B needs about 10.5 GB at Q4_K_M with 8K context, and the best quality that fits is Q6_K.
How fast is the RTX 4070 Ti Super 16GB for LLMs?
About 79 tokens per second for an 8B model at Q4_K_M, based on its 672 GB/s memory bandwidth. Larger models scale down roughly in proportion to their size.
