RTX 5070 12GB for local AI
Fast GDDR7 memory but only 12 GB. Good for 8B to 14B models; for bigger models a 16 GB card is the better choice.
Among the 10 devices we track with about 12 GB of usable memory, the RTX 5070 12GB ranks 2 of 10 for text-generation speed, because generation speed follows memory bandwidth. Others in the same class: RTX 3080 12GB, RTX 4070 12GB, RTX 4070 Super 12GB, RTX 4070 Ti 12GB. They all hold the same models; the faster ones simply answer sooner.
Our picks for the RTX 5070 12GB
The model we would run first for each job, chosen from our recommendations by what fits fully with an 8K context. "Best quant" is the highest quality that fits; "max context" is at Q4_K_M or the native format.

RTX 5070 12GB for LLMs: common questions
Can the RTX 5070 12GB run Llama 3.3 70B?
No. It needs about 43.2 GB at Q4_K_M, far more than the 12.0 GB available.
Can the RTX 5070 12GB run Qwen 3 32B?
Only partly. It needs about 21.4 GB at Q4_K_M, so about 53% fits in VRAM and the rest runs from system RAM, which is slow.
Can the RTX 5070 12GB 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 Q4_K_M.
How fast is the RTX 5070 12GB 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.
