I saw one at guru3d forum today who reached 500w but i doubt he can get records. He said -21c and 2850mhz. Good binned gpu but not the best i guess.
Here is some runs of him at various fire strike:

based on previous experience with AMD, if the 6800XT is nearing the Firestrike world record now, AMD will be number one on that board soon but.... knowing Nvidia/EVGA they will get a frankenstein 3090 from somewhere using technology you can’t buy and they will go through and kill 100 3090 chips just to try and beat the top AMD score.
