A rumor from Asia states that AMD’s newest DX11 chip, to be used in the RV870, could come with a 384-bit memory interface.
This could indeed be possible, concerning that the RV770 is already quite dependent on bandwidth and the RV870 is expected to have twice the computing power. Also the recent information that the chip would be bigger than 300 mm², affirms the theory of 384 Bit memory interface, because already the dimensions of the RV770 would have made it impossible there.
This would put it on-par with NVidia’s G80 chipset, and could double the memory bandwidth of the existing HD4870 card, increasing it to 240GB/s.
