NVIDIA GeForce RTX 3080 12 GB for local AI — common questions
- How much VRAM does the NVIDIA GeForce RTX 3080 12 GB have?
- The NVIDIA GeForce RTX 3080 12 GB has 12GB of VRAM with 912.4 GB/s of memory bandwidth. VRAM sets which models fit; bandwidth sets how fast they feel once they do.
- Is the NVIDIA GeForce RTX 3080 12 GB good for running AI models locally?
- Yes, within limits. 12GB comfortably runs small and mid-size models at a quality quant, but the largest open models will not fit. The largest model it loads cleanly is Mistral-Nemo-Instruct-2407, at a quality quant with llama.cpp at 8K context.
- What runtimes work with the NVIDIA GeForce RTX 3080 12 GB?
- It runs on CUDA · Vulkan, which covers Ollama, llama.cpp and LM Studio. Runtime choice affects speed and features, not whether a model fits.
