Is there a good SDXL photorealistic model ?

I found all SDXL checkpoint really limited on photorealism, even the most populars (realismEngine, splashedMix). Human faces are too "plastic", faces ares awful on medium shots

Flux seems to be way better, but I don't have the GPU to run it

How come 4070 ti outperform 5060 ti in stable diffusion benchmarks by over 60% with only 12 GB VRAM. Is it because they are testing with a smaller model that could fit in a 12GB VRAM?
