It might be a way to improve perf either straight up or by cutting wattage and even with the scrapped big models - assuming that a possible AI crash doesn't have those tapeouts pulled from storage - they likely have RDNA 4's GDDR7 controller taped out if the line was to use it.
It would also increase cost, and Navi43/44 don't need that extra performance. They will probably be slower or at best the same speed as a 7800XT. On the flipside they'll be dirt cheap too, probably with a good chunk of VRAM, so really good low-midrange cards that actually work in games unlike Intel.
Unless AMD is already going for multi-graphics chiplets and they just slap on four Navi43 chiplets to create a flagship. That would be pretty epic and is an option still on the table, they already have a proper functional chiplet design fir their AI cards. But I think we won't see that until RDNA5.
