RV775XT and PRO have 840 SP?

[LordEC911]

Pretty much everyone was saying that, but where did it come from is the question. I can't remember any proper source for that date at the moment. The date could still be valid, nobody except ATI knows what they plan on doing next year. Pretty much the only certainty is RV740 which will be their first 40 nm. chip. It's not sure what kind of chip it is though, w0mbat seems to be hinting that the chip is something more than just a RV730 done on 40 nm. and that it will actually use GDDR5.

You might want to go back and read through the fourth page carefully, lot more information there than you might have realized.
My speculation for RV740 seems to be right on and reaffirms the rumors we heard of tapeouts a few months ago, RV870 in Sept/Oct, RV740 in July.
