Can NVIDIA GeForce RTX 3060 Ti run CogVideoX-5B?
5B parameter Video Gen model on 8GB GDDR6
VRAM Requirements
CogVideoX-5B is a 5B parameter model. At full precision (FP16), it requires 18GB of VRAM. Your NVIDIA GeForce RTX 3060 Ti has 8GB, so you'll need to quantize it to 4-bit (Q4) to fit.
Maximum quality, no quantization
Near-lossless, ~50% size reduction
Good quality, ~75% size reduction
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)
What This Means in Practice
At 4-bit precision, CogVideoX-5B fits in NVIDIA GeForce RTX 3060 Ti's VRAM but video quality may show artifacts, especially in motion consistency and fine details. Generation times will be longer. Usable for experimentation, but a GPU with more VRAM will produce noticeably better results.
