Again only consumer side knowledge but there's clearly very wide degree of variance Navi 31 just from all the models it's used on, as I doubt they're puposefully cutting the silicon that much without the parts already being unusable for more expensive gpus. It goes from a 7900 GRE, 7900 xt to a 7900 XTX with roughly a fifth of the processing unavailable on the lowest tier compared to highest. Then from what I know from overclocking communities the different 7900 XTXs also vary up to over 10% when on the same 550w bios. It's probably more apparent when going over that power limit but that requires hardware modding and people aren't doing that on low tier bins and there isn't as much data.
