I doubt it will be a rebrand.
From the sound of it it is probably either a shrink or they just found a way to make it cheaper. As in manufacture it.
The problem, as always, will be the companies selling it. They just can't resist that urge to be greedy.
To me? it marred the 7800XT. It is priced far higher than it should be, higher than it was for the first few days. Meaning they saw it getting positive reviews and jacked up the prices.
Which to me? it just ruins the whole experience. Which is why I have shied away from buying a lot of hardware. When greed is at play I just don't feel happy buying things.
But yeah, it won't surprise me if this $500 mysteriously ends up being $650. AMD have not done anything even resembling nice for a long time.
