Longtime reader first time poster. I hope my inaugural thread is useful.

Basically they got their hands on an engineering sample of Cayman (not Barts). A few quotes from the translated version, with my editorializing in parentheses:
"Just looking at the back of the card we have noted the points of contact for 8 modules GDDR5 memory, which is then confirmed using a 256bit memory bus size for this card like the 5800 Series solutions. The upper part contains a power connector 6-pin PCI Express flanked by an 8-pin, technical choice identical to that of dual GPU cards ATI Radeon HD 5970, note that the ATI Radeon HD 5800 series are equipped with two connectors PCI Express 6-pin."
(more power hungry than 5870)
"We can then estimate, for this card, the GPU is clocked higher than that made available by ATI Radeon HD 5870, with similar dynamics including the GDDR5 memory, which should significantly exceed the 4800 MHz clock effective solutions Radeon HD 5870 on the understanding the magnitude of the bus."
(higher spec'd GDDR5 RAM, possible increase in core clockspeed)
"The rear panel connections sees the presence of two DVI ports, a standard HDMI and two mini-display port, a configuration like this leaves you can imagine, this type of card, configure the technology Eyefinity up to a maximum of 4 screens used simultaneously."
(Eyefinity4 is likely, up from three screens.)
"...we can also confirm whether there has been a radical change in the structure of stream processors than the solutions chosen for the family R800...."
(Rumors of the 4+1 shader architecture's demise are likely. Most people seem to think it'll be a 2+2 or 3+1 style redesign.)
"We chose not to publish pictures of this card, to protect our source but we can confirm that the card is ready and that the debut would be a matter of no time."
(Production has already started on the replacement to the HD5870, and it should be released soon.)
EDITED TO ADD :
Regarding Barts Pro possible Oct 18 Launch:

The 5750 replacement will apparently have 1120 SPs at ~725 Mhz and 4000Mhz (effective) VRAM on 256-bit bus with 108W TDP. Barts launches sometime on or after the media embargo lift on Monday, October 18. Beyond3D tore the SP number apart though, due to SPs not being properly divisible: http://forum.beyond3d.com/showthread.php?t=55313&page=79 The Oct 18 date remains plausible.
The SWEclockers post I didn't screenshot before they took it down, but luckily VRZone summarized it in time: http://vr-zone.com/articles/-rumour-...pro-/9861.html In case vr-zone ALSO takes it down, I've copied the vr-zone article here:
Swedish website Sweclockers claim to have to scoop on Radeon HD 6850's release date and specifications. A series of previous rumours staded that Barts may be branded as Radeon HD 6800 instead of HD 6700 - a rumour that was received with much skepticism. Sweclockers are now reigniting the same rumour by reporting Barts Pro may end up branded as Radeon HD 6850. The media embargo reportedly ends on 18th October, though a wide availability date is not given.
The specifications, at first sight, appear similar to a Radeon HD 5830, with 1120 SP and 4 GHz 256-bit GDDR5. The clock speed is listed as 72x MHz. On paper, one might wonder why on earth AMD would brand a product seemingly inferior to a HD 5830 as HD 6850? Assuming these rumours have any truth, a radical VLIW-4 / 4D redesign in AMD's shader structure could see even a 1120 SP product outperform the 1600 SP Cypress. Of course, these 1120 SP will occupy a larger area and consume more power.
Meanwhile, a large part of the rumour mill continues to believe Barts will be branded as HD 6700, Cayman as HD 6800 and Antilles as HD 6900, and these just make most sense. The "Barts Pro is 1120SP" specification also disagree with the leaked slide stating Barts Pro as 800 SP. Clearly, there's a lot of uncertainty and misinformation here, with contradictory rumours and something's got to give.
Whichever branding Barts does eventually receive, and whatever its final specifications and performance may be, there's one thing all speculation agrees with - it will release sometime between October 18th and October 25th, with an AMD event scheduled for October 12th. Considering these dates are not much more than a month away, we will surely find out the final and confirmed branding in the coming days/weeks.
