Mac Studio M5 Ultra 512GB vs same-price RTX 5090 rig for local AI video generation

A company wants a dedicated local AI video workstation, and the poster is torn between a Mac Studio M5 Ultra 512GB and a same-price high-end Nvidia build (RTX 4090/5090). Their pipeline relies on ComfyUI running models like Wan and MiniMax H3; they ask whether real-world macOS performance is practical for daily video generation or whether an Nvidia rig is non-negotiable. Discussion weighs unified memory against CUDA ecosystem and generation speed.
