I couldn't find recent summarized data for the (excellent) benchmarks provided via the sd-extension-system-info repo, so I went ahead and pulled/summarized it. Here is the median It/s for each GPU with more than 10 entries in the table (single GPU setups only).

Note: updated (found an error in the original post where I hadn't actually eliminated dual GPUs etc.)
Because the data was pretty noisy, I filtered out everything with <10 benchmarks. I manually checked the source (listed in the header post) and it looks like there are 2 benches for that card, and they yielded 4.93it/s and 6.38it/s.
That kind of variability is why I constrained it to 10+ measurements and took the median to exclude outliers.
