New rumor about ATI Southern Islands

[LordEC911]

For those of you that missed it...

hmm, may i speculate ? Bart would be a 1280 SP (320*4) 16 ROP 128 bit chip 240-260 mm^2 performance ~HD 5850, Cayman would be a 1920 SP (480*4) 32 ROP 256 bit chip 390-420 mm^2 performance ~GF100 512 SP+, and dual Cayman power consumption would be very, very close to PCIE standard limit of 300 w, unlike HD 5970 TDP which is rather conservatively rated, or would simply be underclocked further compared to its older dual chips kamerad. This speculation is reasonably explaining the rumored TDP of the chips reported in the article.

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