Interestingly, the 7900 currently costs more than the 7900x (quick Amazon search). And my understanding is the 7900 is just the 7900x that has its TDP defaulted to 65 watts. So you could buy the cheaper 7900x and just go into BIOS and limit the TDP to make it a 7900.

7900 comes with a (supposedly decent) fan, 7900X does not.

I would bet that the 7900X chips are binned for higher quality Silicon though. Makes you wonder if an underpowered 7900X outperforms a 7900 and by how much.
