Systematic Optimization of Real-Time Diffusion Model Inference on Apple M3 Ultra

In three linesSystematic optimization of real-time diffusion models on Apple M3 Ultra (60-core GPU, 512 GB unified memory). CoreML conversion of SDXS-512 distilled model combined with 3-thread camera pipeline achieves 22.7 FPS at 512×512 resolution. Demonstrates that CUDA optimization insights do not transfer to Apple Silicon's unified memory architecture.
