Which GPU is better for local AI workloads?
The 3060 12GB's unusual 360 GB/s on a wide 192-bit bus makes aged-but-agile LLM decoding surprisingly competitive; the 4060 Ti 16GB's narrow 288 GB/s was its Achilles heel despite more capacity. For 8B models the 3060 decodes faster; for 12B–14B models the 4060 Ti's 16GB is required.

What about price?
Which one should you buy for LLMs and image generation?
GeForce RTX 3060 12GB
Buy a used 3060 12GB under ~$250 for the cheapest solid 8B/SDXL experience.
Full specs & benchmarks →GeForce RTX 4060 Ti 16GB
Buy the 4060 Ti 16GB used for 12B–14B models — or better, the newer 5060 Ti 16GB with 448 GB/s.
Full specs & benchmarks →Is it faster for LLM inference?
8B at Q4: 3060 often faster (360 vs 288 GB/s). 12B+ models: only 4060 Ti holds them.
How does it handle image generation?
SDXL workable on both; 3060's bandwidth helps step times, 4060 Ti's capacity helps batching.
Which AI models fit on each card?
Computed from our model VRAM database at Q4 quantization: GeForce RTX 3060 12GB has 12 GB, GeForce RTX 4060 Ti 16GB has 16 GB.

Frequently asked questions
Why is the RTX 3060 12GB still recommended for AI?
12GB VRAM for used prices near $200–250 plus 360 GB/s bandwidth — more bandwidth than the newer 4060 Ti — makes it the budget local-LLM standard.
Is the 4060 Ti 16GB worth it over a used 3060 12GB?
Only if you need 12B–14B models that exceed 12GB. Its 288 GB/s bandwidth is slower than the 3060's 360 GB/s, so shared models run slower.
