If slide leaked on Orb-Hardware is to be believed we GPU consumers are in for a pretty big treat in the next month or so. The slide shown below states that the AMD 7970 will have a default core clock speed of 925MHz and a whopping 3 GB of GDDR5 memory.

It also sports a 3.5 TFLOPs precision floating point. Which would put it well beyond the NVIDIA flagship single GPU solution. The slide states the a ROP count of 32, against an earlier speculated count of 48. This could be because AMD may have delinked ROP clusters from memory bus. The cooler itself is under the trademark AMD black shroud so there is no way to see if it uses the rumored "vapor chamber" as seen in after market solutions.

Looking past all the beastly prowess of this slide one cannot help but think about power draw. The "leaked" slide states the 7970 will have a peak power draw of 300 W and an idle draw of 3 W. We will have to wait for review to see if any of these amazing stats are true.

In a surprising move, AMD pulled the launch date of Radeon HD 7970, a high-performance single-GPU graphics card based on the 28 nm Tahiti silicon, up to December 22, 2011; from its earlier launch date of January 09, 2012. The January date was a lot more than speculation, as older presentation slides from AMD to distributors and retailers talked specifically about it. The move to pull December 22 (next Thursday) spices things up in the run up for CES. First, it gives AIB partners full freedom to show off their custom-design graphics cards at the event, along with full details about GPU specifications and clock speeds.

According to a VR-Zone report, Radeon HD 7970 will launch on December 22, 2011, this will be the day you will be able to read reviews of the card (at least the AMD reference design board), online. It will be a limited launch (read: paper-launch), but one can expect "full" retail availability of the card by January 09. Another interesting bit of information is concerning the Radeon HD 7950. This card will be available in non-reference board designs from day one, it will however launch on January 09.

Reliable sources among AMD add-in board partners told DonanimHaber that the upcoming AMD Radeon HD 7900 series will introduce a new feature that other SKUs based on Southern Islands GPUs could also include. It's called Eyefinity 3D, and as the name might suggest, it's the next major update to Eyefinity, a technology that lets you span a single display head across up to six physical displays, and gives you the ability to use your available physical displays to accommodate multiple such display heads.

Eyefinity 3D adds support for 3D-optimized (120 Hz) displays, and lets you create large stereoscopic 3D display heads using a number of physical 3D displays. The technology behind this might not be as simple as it sounds, because the driver has to take into account the viewing angles of the displays in perspective to the user (as entered by the user), and calibrate the 3D image output. The same sources also hinted about the pricing of Radeon HD 7970.

A Beyond3D forum member posted a mysterious picture of two graphics cards that could very well be engineering samples of AMD's true next-generation Radeon HD 7900 "Tahiti" graphics cards. The final products most probably won't look like these, with a bare red PCB, but it does look like the reference cooler design is ready. A more important feature in that picture is the spotting of traces for at least 11 memory chips, the 12th one (not highlighted) is apparently near the PCIe slot interface. The presence of 12 memory chips gives rumors of Tahiti featuring a 384-bit wide memory interface a shot in the arm. This will be the first AMD GPU in over 5 years to feature a memory bus wider than 256-bit. The R600 Radeon HD 2900 GPU featured a 512-bit GDDR4-capable memory interface.

AMD is on course to releasing its latest "Southern Islands" GPU family, and a fleet of desktop graphics card SKUs based on it, which will be led by a new high-performance GPU, codenamed "Tahiti", which will make up Radeon HD 7900 series; followed by performance GPU "Pitcairn", on which HD 7800 series will be based; "Thames" and "Lombok" making up the rest of the lineup. According to a report by DonanimHaber, HD 7970 (working name) is expected to be competitive with (or outperform) GeForce GTX 580, and priced at US $499. The HD 7950 will be competitive with (again, or outperform) GeForce GTX 570, being priced at US $399.

Things get interesting with Pitcairn, which is the successor of "Barts". This performance GPU is designed for sweet-spot SKUs, such as HD 7870 and HD 7850, which will be competitive with GeForce GTX 560 Ti / GTX 560, and priced at US $299 and $199, respectively. The Radeon HD 7670 will be particularly expensive, priced at US $179, followed by HD 7650 at $119. Further, it was reported that HD 7970 and HD 7950 will have a standard memory size of 3 GB.
