AMD x ComfyUI: Advancing Professional Quality Generative AI on AI PCs

As models grow, many creator workflows have drifted to distant cloud services. With AMD ROCm™  7.1.1 and the new one click ComfyUI experience on AMD, creators can bring power back to local devices where they have more control over cost, data and iteration speed.

ComfyUI Integration powered by AMD ROCm™ 7.1.1

ComfyUI has become the control room for advanced diffusion workflows. Power users design node-based workflows, try out state of the art models and share templates that spread quickly through the community.

The ComfyUI installer for Windows eliminates most of the friction associated with setting up ComfyUI. It arrives pre-packaged with AMD ROCm™ 7.1.1 and tuned pipelines for popular models, so users can move from install to first image in just a few steps on supported AMD Ryzen™ AI systems or AMD Radeon™ AI based workstations.  

Three ways to install ComfyUI on AMD

We are excited to announce that AMD ROCm™ support is now natively integrated into ComfyUI - including the Desktop application. To meet different user needs, there are now three supported ways to install ComfyUI on AMD hardware:

1. Official Windows .exe installer
   An easy GUI-based installer for Windows that handles dependencies and configuration for you, powered by AMD ROCm™ 7.1.1. Download here. AMD recommends an AMD Ryzen™ AI Max+ 128GB system (set to 64GB VGM) or an AMD Radeon™ AI Pro R9700 (coupled with 64GB RAM) for the optimal experience.
   
   
2. Official portable Windows build from the ComfyUI GitHub repository
    A portable archive that can be downloaded and unpacked, also powered by AMD ROCm™ 7.1.1, ideal for users who want a contained folder they can move between systems. The latest portable release can be downloaded directly from the ComfyUI Github repository.
   
   
3. Manual setup through git
    For developers who prefer full control, ComfyUI can still be installed manually and paired with AMD ROCm™ nightlies for early access to upcoming features, expanded support and optimizations. Detailed instructions can be found here.

Across all three options, the aim is the same: let users choose the level of control they want without sacrificing performance on AMD platforms. 

AMD ROCm™ 7.1.1 powers up to 5.4x performance uplift in advanced models

AMD ROCm™ 7.1.1 builds on the foundation of ROCm 6.4 and delivers up to 5.4x performance uplifts in ComfyUI on Windows.

Along with performance improvements, and when coupled with the AMD ROCm 7.1.1 driver (which will soon be part of the main-line AMD Software: Adrenalin™ Edition drivers in an upcoming release), it delivers a host of stability improvements: a more consistent experience across AMD Ryzen™ AI powered devices, AMD Radeon™ and Radeon™ AI PRO GPUs, continued tuning for mixed precision formats such as FP16, BF16 and FP8, and better memory handling.

For users, the technical work shows up as faster renders, fewer crashes and workflows that transfer more easily between machines. This release marks the first (Beta) release of the AMD x ComfyUI experience – with more performance and stability improvements on the way. 

Modern image quality needs State of the Art models

The visuals themselves tell an important story. Early (and now dated) diffusion models such as Stable Diffusion 1.5, with about 0.9 billion parameters, could generate an image in a few seconds on an AMD Ryzen™ AI Max+ system, but the quality was not usable in professional contexts. Faces often looked distorted and fine details like hands, text or structural details were garbled. These models were impressive for their time, yet they were not close to true photo quality.

Creators now expect much more. Newer models such as Z Image Turbo in the 6 billion parameter range, produce scenes with realistic lighting, sharper textures, convincing anatomy and superb text handling. Skies have depth, skin tones look natural and small details such as reflections or fabric folds hold up under scrutiny. 

At the high end, Flux 2 reaches about 32 billion parameters in FP8. An AMD Ryzen™ AI Max+ system can handle the model if needed, while AMD Radeon™ AI PRO graphics cards provide significantly faster acceleration. Similarly, large video models such as WAN 2.2, at about 14 billion FP8 parameters, provide superb visual fidelity and video dynamics – with long render times.

Because ComfyUI runs on top of AMD ROCm™ 7.1.1 across both environments, teams can prototype on portable hardware and then scale up without changing tools or workflows. 

AMD ROCm™ 7.1.1 lets ComfyUI do what it does  best so creators can choose between quick turnaround or higher polish as needed. For studios and enterprises, that means rough cuts, product explainers and visual experiments can often be generated locally, with workstation capacity reserved for final, heavy production runs.
