The release of Radeon HD 7970,A lower version with a lower price also for the enthusiasts featuring the same Graphics, 28nm GPU architecture .
The Radeon HD 7950 is a Tahiti-class GPU code named "Tahiti Pro" same as the one on the HD 7970 but with lower Compute Units number.
A slide leaked show specifications of the card, with lower transistors number 4.3 billion transistor, 1792 Compute Units compared to 2048 units on the HD 7970, the GPU is connected to 3GB of GDDR 5 using the same 384-bit bus with 5Gbps transfer speed, one DVI, one HDMI and two mini-DisplayPort video outputs as well as PCI Express 3.0 and DirectX 11.1 compatibility, the memory speed is not announced yet but we guess it would be about 150Mhz lower than the HD 7970.
The price and release date is still unknown, for sure they will appear very soon so check us as soon as possible.
The Radeon HD 7970 use new 28nm process technology helping to get more performance and low power consumption, so the Radeon HD 7970 is now the fastest single GPU graphic card with 925MHz core clock that can reach 1.1Ghz when OC'd, packing 2,048 stream processors and a wide 384-bit memory bus interconnected with 3GB of GDDR5, using PCI-E 3.0, the price is 200$ more than previous HD 6970, set to $549.
High-end HD 7900 series GPUs will be named as Tahiti Pro and XT variants, and the monstrous dual GPU card as New Zealand, these GPUs make use of the new Graphic Next Core architecture (GCN). The implementation of GCN, a more programming friendly architecture is not only to improve the performance but also to improve the functionality of GPGPU applications.

28nm HPL Technology from TSMC
TSMC’s 28 nanometer HPL technology, which provides High Performance with Low-Power consumption. AMD Radeon HD 7870 have a maximum power consumption of only 120 watts, compared with 250 watts of the 40nm-made predecessor, whereas Pro-Thames, Lombok XT and Lombok Pro, all use the same power efficient 28nm technology, with consumption ranging from 90 watts down to 50 watts.

Apparently AMD is in its efforts to maintain a good balance between bandwidth and the memory bus, only so AMD would have chosen to abandon the use of GDDR5 memory and instead use XDR2 Rambus memory. Currently AMD pays royalties to Rambus on the use of its memory technologies for several years, so it would not sound strange upon AMD’s decision to implement them in their chips.

XDR2 Rambus Memories Performs more but costs more too

First Stage of Filtered Data
These cards can be expected to be released in between October to December of this year, Q4 2011. But high end HD 7900 series are expected to be released in Q1 2012. It is too early to get a complete picture of what AMD has prepared for us, and these details or rumors cannot be taken as a valid or official information. These are just first stage of filtered data, and we have no doubt that in the coming days / weeks, there will be many more like this, and even there may be some showing performance reviews of Radeon HD 7000 series.

figured i would post it here so you didn't have to leave OCF.
