Benchmarking local Stable Diffusion 1.5 generations on iPhone 17 - only 3 seconds per image

I’ve been testing local Stable Diffusion 1.5 generation on an iand wanted to share the numbers, since most SD benchmarks are still desktop/GPU-focused Setup: - Device: iOutput: 512x512 - Compute: CPU + Neural Engine - 3 models x 3 prompts x 3 takes = 27 total generations - final sheet shows the best generation for each prompt/model pair - timings are warm runs, with model packs already installed/prepared Models/settings tested: CyberRealistic | DPM Solver Multistep / Karras | 30 steps / CFG 7 | 13.6s DreamShaper 8 LCM | LCM / Leading | 10 steps / CFG 2 | 4.5s Realistic Vision V5.1 Hyper.
