It's pretty widely speculated that Hainan (Pitcairn successor) will have 1,792 stream processors; 112 TMUs, 32 ROPs and 256-bit memory bus with clocks in the 1000+(core) /1500 (memory) range. That aside, do you believe this will see a release before H2 2013, which is when Curacao (Tahiti successor) is speculated to hit the market?

I speculate that the Malta HD 7990 will use Hainan rather than Tahiti as it requires only two 8-pin power connectors vs three for the custom model HD 7990s. Since it's supposedly far more power efficient than Tahiti due to the reworked power state of GCN 1.1, I imagine they could easily overclock the hell out of it so it surpasses the Ares II or Devil 13 HD 7990s.

32 ROPs with 256-bit memory? Somebody is high as a kite.

How do you figure? That's the same configuration as Pitcairn. However, there are some new rumors about Curacao and Hainan, courtesy of Chiphell (http://www.chiphell.com/thread-755237-1-1.html):

If this is true, there's quite a big gap between HD 8970 and HD 8950...

Pay her no mind, UT.

Huh, I didn't know AMD had 32 ROPs all the way down to 7850. Seems silly! Grossly unbalanced on the fillrate side there. I wonder if that's to support Eyefinity better on the lower-spec cards? Curious. ('∀`) Anyway, I was mistaken/wrong, so, sorry about that.

Looking back I think I was confusing Pitcairn for Tahiti and then reading the projected Hainan specs as "8970" (although I doubt Hainan/Curacao will be HD 8000 series, personally). So, obviously, a bit silly. Hehe. `,､('∀`) '`,､
