Sounds spot on to me other than the fact that Barts should be 256bit since Turks is the 128bit part.

The above was provided by neliz.
Yeah the buswidth and the ROP seems quite puzzling to me up to this moment. I think if ATi push for 384 bit for Cayman & 256 bit for Bart, they won't be pad limited, but the die size might grow excessively since 384 bit means 48 ROP & 256 bit 32 ROP consecutively. But with the slowing of GDDR speed increasing pace & the added die size from core improvement using the same process node, it's quite reasonable for them using the larger buswidth & the associated added ROP, if the chip performance justifies that. OTOH, that would mean the end of sweetspot strategy, or not ? aarrggh, i should stop speculating by now, a layman shouldn't think too much out of his league.
