Verdict

Both run on a 12 GB card, but it is a long wait for one image. They held together at that size, so if you need a really big picture, either one is worth the wait.

Photograph of a man with short black hair, a trimmed beard and a white linen shirt with rolled sleeves, standing in front of a small corner cafe at golden hour. Above the door a hand-painted wooden sign reads "THE SLOW KETTLE" and a chalkboard beside him reads "Fresh bread at 7. Open late on Fridays." Warm light, shallow depth of field, 35mm photo.

Notes

The official Base template at 4 megapixels (2048×2048). The LoHa is comfyanonymous's hi-res test LoRA v0.5 at 1.0, for Base. Scale ROPE is a native ComfyUI node, set to 0.5 × 0.5 (NTK scaling from 1024 to 2048). 2048 plain has neither.
