"Fits in VRAM" = fast, fully on GPU. "Offload" = part on system RAM, slower. Speed is a rough estimate.
Frequently asked questions
What is the VRAM and memory bandwidth of the NVIDIA RTX 3080 Ti?
The NVIDIA RTX 3080 Ti features 12 GB of VRAM and a memory bandwidth of 912 GB/s (GDDR6X 384-bit). In local language model inference, VRAM determines which model sizes fit on the card, while memory bandwidth dictates how many tokens per second the GPU generates.
What is the best local AI model to run on a NVIDIA RTX 3080 Ti?
The best overall model for the NVIDIA RTX 3080 Ti is unsloth/Qwen3-Coder-30B-A3B-Instruct-GGUF using the recommended Q2_K_L quantization (11.73 GB total memory). With 12 GB of VRAM, this GPU typically runs a 14B model at Q5, comfortably at full GPU speed. Check our guide to the best LLMs for 12 GB VRAM for details.
Can the NVIDIA RTX 3080 Ti run 14B models locally?
Yes. The NVIDIA RTX 3080 Ti's 12 GB VRAM is the exact sweet spot for running 14B models (such as Qwen 2.5 Coder 14B) in Q4_K_M quantization (~9.2 GB footprint) with full 4,096-token context entirely in VRAM.
What power supply (PSU) do you need for the NVIDIA RTX 3080 Ti when running local AI?
The NVIDIA RTX 3080 Ti has a rated TDP of 350W. While local inference typically draws less power than full 3D rasterization or gaming, continuous token generation can sustain high loads. A quality power supply of at least 650W is strongly recommended.
