Moore's Law Is Dead said these could also possibly be the 7600XT cards while Navi 32 could be the 7700XT. I know Navi 31 seems to be a 6900XT replacement in part and is quite different than Navi 32, but a cutdown variety could be the 7800XT like it is with RDNA2. Or alternatively Navi 32 could be 7800XT while a cutdown variant of it could be the 7700XT.
