Any reliable benchmark comparisons that include the 50 series (Down to 5070)

I think I am having problems with my 3090, and don't want to spend a fortune to replace it (And actually want to be able to find one) so I was looking at the 5070, and it seems that although it only has 12 GB Vram, it benches a bit faster, at least in gaming performance. And is the 5080 worth the extra money in relation to Stable Diffusion?

There is a wonderful chart I have seen out there, but it ends at the 40 series..

If there aren't any benchmark charts out there, how about some advice? I care pretty much zero about gaming. Its just about the AI usage.
