Can NVIDIA GeForce RTX 4060 Ti 8GB 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 4060 Ti 8GB 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 4060 Ti 8GB'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.
