SD Upscale on img2img is GoBig, it just needs to be added to the extras tabs.
The new "High res fix" in txt2img is even better because it generates a low-res picture and runs SD again on it. You can even do it while still in latent space. It should alter the composition less than SD Upscale/GoBig.
txt2imghd is a port of the GOBIG mode from progrockdiffusion applied to Stable Diffusion, with Real-ESRGAN as the upscaler. It creates detailed, higher-resolution images by first generating an image from a prompt, upscaling it, and then running img2img on smaller pieces of the upscaled image, and blending the result back into the original image.

Edit: ok after testing it, I'm not sure if it's worth adding it since it's very slow and the result wasn't great for me. since it splits the images into pieces, I'm not sure one prompts is going to be enough to get a good result since each peace needs different prompts like part of the image is a window and another part is a character, you can't apply one prompts for both sections.
