Stability AI, the company behind Stable Diffusion, hasreleasedONNX-optimized models that run up to 3.3x faster on compatible AMD hardware, including selectRadeonGPUs and Ryzen AI APUs on mobile.
Amuseis a platform developed by AMD and TensorStack AI that allows users to generate images and short videos locally, on AMD hardware. The latestAmuse 3.0release not only supports these updated models but also introduces a range of new features, including video diffusion, AI photo filters, and local text-to-image generation. Amuse 3.0 and AMD optimized models require the Adrenalin 24.30.31.05 preview drivers or the upcoming Adrenalin 25.4.1 mainline release.
Over the past year, AMD has partnered with several OSVs, OEMs, and ISVs to optimize AI applications from the ground up, incorporating hardware optimizations, efficient drivers, compilers, and optimized ML models, among other enhancements. Building on this partnership, Stability AI has launched Radeon-optimized versions of its Stable Diffusion family, which include Stable Diffusion 3.5 (SD3.5) and Stable Diffusion XL Turbo (SDXL Turbo). First-party metrics report a 3.3x speedup with SD3.5 Large, dropping to 2.1x for SD3.5 Large Turbo and 1.5x for SDXL Turbo compared to the base PyTorch implementations.
Artificial Intelligence is an integral part of our daily lives, but most of it lives in the cloud and requires an active internet connection. “AI PCs” are driving the development of modern processors, which feature dedicated hardware units to accelerate machine learning operations. Take NPUs and specialized AI matrix cores, for example, which allow smaller and efficient AI models to be run locally.
RDNA 4features AMD’s second-generation AI accelerators, which offer 4x more FP16 performance (with sparsity), doubling to 8x with INT8 (again, with sparsity) versus RDNA 3. These optimized models are not architecture-bound, although AMD mandates high-end GPUs for certain models, such as SDXL, SD 3.5 Large, and Turbo. Ryzen AI APUs can leverage the built-in XDNA NPU in tandem with the Radeon iGPU. In this case,Strix Halois the recommended choice due to its large memory buffer and raw horsepower.
Stable Diffusion models optimized for AMD hardware are tagged with the “_amdgpu” suffix and are now available for download atHugging Face. With the necessary hardware, you’re able to launch these models immediately in your preferred environment or AMD’s Amuse 3.0, whichever suits your needs.
