The machine with the most memory made my AI picture slowest. 7.3 s on a DGX Spark, 1.7 s on an RTX 5090. DGX Spark (128 GB): 7.3 s per image RTX 5090 (32 GB): 1.7 s per image RTX 5060 Ti (16 GB): 5.8 s per image Qwen Image 2.1 Turbo, int8, 1024x1024, 8 steps ComfyUI 0.39.0, Comfy-Org template settings, same files on all three Median of 6 prompts, seed 42, one image at a time Spark clock capped at 2200 MHz The Spark has the most memory but the least bandwidth, 273 GB/s against 1,792 on the 5090 (NVIDIA spec). Every step reads the whole model from memory, so that may be one reason. Credits:
