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.
Ultra-detailed wide photograph of a desert canyon at sunrise: layered red sandstone walls, a winding river far below, a lone hiker in an orange jacket on a ledge in the foreground, tiny juniper trees, scattered rocks, distant mesas under a clear sky.

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.
