Full specs & benchmarks →Is it faster for LLM inference?
For token generation the 3060 12GB is faster (360 versus 272 GB/s) and fits larger models (12GB versus 8GB), making it the straightforward LLM pick. The 4060 wins only on power efficiency and prompt processing.
How does it handle image generation?
The 4060 generates Stable Diffusion images faster thanks to Ada\u2019s FP8 tensor throughput, but SDXL is tight on 8GB while comfortable on the 3060\u2019s 12GB.
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 has 8 GB.
Fit on both cards
Frequently asked questions
Is the RTX 4060 faster than the 3060 12GB for LLMs?
No. LLM token generation is memory-bandwidth-bound, and the 3060 12GB has 360 GB/s versus the 4060\u2019s 272 GB/s, plus 4GB more capacity for larger models.
Why does the older 3060 have more VRAM than the 4060?
NVIDIA kept the 4060 at 8GB on a 128-bit bus to hit its $299 price point, while the 3060 12GB used a 192-bit bus. It is an unusual case of the older card carrying more memory.
Which is better for Stable Diffusion?
The 4060, on speed: Ada\u2019s FP8 tensor cores outpace Ampere per core. But SDXL at high resolutions fits more comfortably in the 3060\u2019s 12GB.
