NVIDIA GeForce RTX 3090 Ti for local AI — common questions
- How much VRAM does the NVIDIA GeForce RTX 3090 Ti have?
- The NVIDIA GeForce RTX 3090 Ti has 24GB of VRAM with 1010 GB/s of memory bandwidth. VRAM sets which models fit; bandwidth sets how fast they feel once they do.
- Is the NVIDIA GeForce RTX 3090 Ti good for running AI models locally?
- Yes. 24GB is enough headroom for the large open models most people want to run locally. The largest model it loads cleanly is Qwen3-30B-A3B, at a quality quant with llama.cpp at 8K context.
- What runtimes work with the NVIDIA GeForce RTX 3090 Ti?
- It runs on CUDA · Vulkan, which covers Ollama, llama.cpp and LM Studio. Runtime choice affects speed and features, not whether a model fits.
