It's important for people to specify which 5700XT GPU, because there are minor variations (ROW, hardware, cooling, etc) between vendors that can wreak havoc if the drivers don't account for these variances.

Could you provide some evidence for that statements? As long as the fan curves are good enough to cool the card, then nothing really should be different between different 5700xt cards.
