maybe , but do u have proof of this ?
I remember stories of nvidia 512bit cards vs 256bit cards and the theory then
was they didn't "upgrade" the 256bit ones to 512bit purely as a marketing
point , since the alleged preformance of 256bit card (upgraded to 512bit) would be equal to the standard 512bit one....

And I aggree with the idea that the 4870x2 for example is suffering from the
256bit bottle neck ....seems to make sense.
just my useless 5c lol..
