WA Can I run Wan 2.2 T2V A14B on AMD Radeon RX 7900 XTX (24GB)?
Yes. Wan 2.2 T2V A14B runs on AMD Radeon RX 7900 XTX (24GB) at Q4 GGUF (~16 GB of ~23 GB usable).
Runs at Q4 GGUF using ~16 GB of ~23 GB usable.

How to run it
Use ComfyUI or Diffusers at Q4 GGUF. The big text encoder is loaded to encode your prompt, then offloaded before generation, which is why peak VRAM stays near the backbone size rather than the sum of every file.

FAQ
Can AMD Radeon RX 7900 XTX (24GB) run Wan 2.2 T2V A14B?
Yes. Wan 2.2 T2V A14B runs on AMD Radeon RX 7900 XTX (24GB) at Q4 GGUF (~16 GB of ~23 GB usable).
How much VRAM does Wan 2.2 T2V A14B need?
AMD Radeon RX 7900 XTX (24GB) has room to spare. At Q4 GGUF the realistic peak is ~16 GB of VRAM, versus ~80 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 Wan 2.2 T2V A14B locally?
Wan 2.2 T2V A14B runs in ComfyUI or Diffusers. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
