Can I run HunyuanVideo on Nvidia GeForce RTX 4070 (12GB)?
Needs ~16 GB at Q4 GGUF, but only ~11 GB is usable on Nvidia GeForce RTX 4070 (12GB). With aggressive CPU offload it can run on as little as ~8 GB, much slower.
Needs ~16 GB at Q4 GGUF, but only ~11 GB is usable on Nvidia GeForce RTX 4070 (12GB). With aggressive CPU offload it can run on as little as ~8 GB, much slower.
The gap is about 5 GB: HunyuanVideo needs roughly 16 GB and Nvidia GeForce RTX 4070 (12GB) leaves only about 11 GB usable for a model. The lightest tracked hardware that runs HunyuanVideo is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See HunyuanVideo on Nvidia GeForce RTX 4090 (24GB).

FAQ
Can Nvidia GeForce RTX 4070 (12GB) run HunyuanVideo?
Needs ~16 GB at Q4 GGUF, but only ~11 GB is usable on Nvidia GeForce RTX 4070 (12GB). With aggressive CPU offload it can run on as little as ~8 GB, much slower.
How much VRAM does HunyuanVideo need?
Nvidia GeForce RTX 4070 (12GB) does not have enough memory. At Q4 GGUF the realistic peak is ~16 GB of VRAM, versus ~60 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~8 GB, much slower.
What do I use to run HunyuanVideo locally?
HunyuanVideo runs in ComfyUI. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
