Interesting. But it's not in line with the driver info, which indicates the same architecture for Tahiti and Pitcairn:
AMD68FA.1 = ati2mtag_Evergreen = "AMD Radeon HD 7300 Series"
…
AMD675B.1 = ati2mtag_NI = "AMD Radeon HD 7600 Series"
AMD6751.1 = ati2mtag_NI = "AMD Radeon HD 7600A Series"
…
AMD6859.1 = ati2mtag_R475 = "AMD Radeon HD 7400 Series"
AMD6840.7 = ati2mtag_R476 = "AMD Radeon HD 7600M Series"
AMD6841.7 = ati2mtag_R476 = "AMD Radeon HD 7500M/7600M Series"
AMD6799.1 = ati2mtag_R575 = "SI NEW ZEALAND"
AMD679A.1 = ati2mtag_R575 = "SI TAHITI PRO"
AMD6798.1 = ati2mtag_R575 = "SI TAHITI XT"
AMD683B.1 = ati2mtag_R575A = CAPE VERDE PRO
AMD6819.1 = ati2mtag_R575 = "PITCAIRN PRO"
AMD682F.1 = ati2mtag_R576 = "CHELSEA PRO"
AMD6824.1 = ati2mtag_R576A = "CHELSEA XT"

Are they implying, that AMD replaced XDR2 memory controller by GDDR5 MC just a few weeks before launch?Another advantage of the 7000 series is that they will use the PCIe 3.0 bus on motherboards, while the use of new memories XDR2 seems to be left for later. A Rambus memory design would offer a higher bandwidth (up to 8,000 MHz) but the cost may pile up a bit more and that’s why AMD could have been suggested to go with GDDR5 itself.
Where is all this fake XDR2 crap coming from? I look at a chart that looks completely believable and then I see that and it's like
Especially this paragraph is quite funny...

If you're assuming 384bit gddr5 it most likely can't really be anything else than 48 ROPs and I would guess that's why someone changed the wiki.I know this info is to be taken with a truck load of salt, but the wiki page for Southern Islands has changed.
7970: 2048:128:48 where 48 = ROPs. This definitely said 64 last week. Is someone in the know already?
I don't know why, but my expectation for a 7970 just cratered...
Does not look believable to me anyway. In particular for GCN disabling of "clusters" should come in groups of 4 (and btw the power draw would be fantastic news but I see no reason why both nvidia and amd wouldn't go to the same limits as before).Where is all this fake XDR2 crap coming from?

Hmm funny that so wichita/krishna cpu is scrapped and the IGP of it still scheduled to launch? That doesn't add up .

So in a nutshell, model [BLANK] will have [BLANK], up to [BLANK], and even [BLANK] for a power consumption of just [BLANK]. Impressive.
It looks like our "onepage saleskit" but this screecap has errors in it.. sorry to disappoint you guys

I understand you.
But this one is much better and at least there is a source.

Any hints about the DX support?
The card dimensions too...
Only half of the bars are plausible?This seems half-plausible.
