As usual, we have the 4090 synthetic and gaming benchmark. What's really relevant to us DC crunchers here is the gpu crunching efficiency. Taken from der8auer video with this timestamp here, one can roughly deduce the power limit to use when doing DC crunching. Worth watching this segment of the video. Less than 3 minutes long.

Best to run anywhere from 50% to 60% power limit. Similar to what I found out with the gtx 970 crunching efficiency almost 6 years ago.

As a reference, gtx 970 PPD/W peak crunching efficiency for GFN-18 project is around 55% power limit.
