RTX 3060 12GB vs RTX 5060 Ti 16GB: which is better for local AI?
12GB against 16GB, 360 against 448 GB/s. What each runs, how fast, and which one to buy.
The verdict
The RTX 5060 Ti 16GB has 4GB more memory (16GB vs 12GB), so it runs larger models, such as Qwen3.8 27B, without offloading. The RTX 5060 Ti 16GB generates text about 36% faster thanks to 448 GB/s of memory bandwidth versus 360 GB/s. The RTX 3060 12GB costs about $350 less ($270 used vs $620).
- Get the RTX 3060 12GB if you want the most for your money.
- Get the RTX 5060 Ti 16GB if you want to run bigger models or use longer context, speed matters most, or you want a new card with a warranty.

Our take
Bottom line on each
The cheapest sensible CUDA card for local AI, good for 7B to 14B models.
The cheapest new way to get 16GB of CUDA memory, and a strong first LLM card.
Frequently asked questions
Is the RTX 3060 12GB or RTX 5060 Ti 16GB better for running LLMs?
The RTX 5060 Ti 16GB has 4GB more memory (16GB vs 12GB), so it runs larger models, such as Qwen3.8 27B, without offloading. The RTX 5060 Ti 16GB generates text about 36% faster thanks to 448 GB/s of memory bandwidth versus 360 GB/s. The RTX 3060 12GB costs about $350 less ($270 used vs $620).
How much faster is the RTX 5060 Ti 16GB than the RTX 3060 12GB for AI?
About 36% faster at generating text in our estimates, because token generation is limited by memory bandwidth (448 GB/s vs 360 GB/s). Prompt processing depends more on compute and can differ by more.
Can the RTX 3060 12GB and RTX 5060 Ti 16GB run the same models?
No. The RTX 5060 Ti 16GB fits models the RTX 3060 12GB can only run with CPU offload, including Qwen3.8 27B, gpt-oss-20b, and Gemma 4 26B A4B.
