A Reddit user benchmarked Qwen Image 2.1 PE text-to-image across step counts and resolutions: 25-35s per image on an RTX 4090 with the Prompt Enhancer enabled, versus 5-7s without it. Fifteen prompt categories were tested (portrait, cinematic, 3D character, architecture, fashion, food, surreal, complex composition, etc.), with results hosted on Imgur. The takeaway: PE noticeably improves quality at roughly a 5x time cost.
