"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 3090 Ti?
The NVIDIA RTX 3090 Ti features 24 GB of VRAM and a memory bandwidth of 1008 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 3090 Ti?
The best overall model for the NVIDIA RTX 3090 Ti is unsloth/Qwen3-Coder-30B-A3B-Instruct-GGUF using the recommended Q5_K_XL quantization (21.42 GB total memory). With 24 GB of VRAM, this GPU typically runs a 30–35B model at Q5, fully on the GPU at full GPU speed. Check our guide to the best LLMs for 24 GB VRAM for details.
Can the NVIDIA RTX 3090 Ti run 70B parameter models like Llama 3.3 70B?
Yes. With 24 GB of VRAM, the NVIDIA RTX 3090 Ti can run 70B parameter models quantized to 3-bit or 4-bit (such as IQ3_M or Q4_K_M) with moderate context windows (4k tokens). For larger context windows (16k+), pairing with a second GPU or slight CPU offloading may be required.
What power supply (PSU) do you need for the NVIDIA RTX 3090 Ti when running local AI?
The NVIDIA RTX 3090 Ti has a rated TDP of 450W. 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 750W is strongly recommended.
