AMD Radeon HD 6000 Series :

AMD released the Radeon HD 6870 and the Radeon HD 6850, the first two models in its new 6000 series of video cards. These cards, respectively priced at $239 list and $179 list, are aimed at directly challenging Nvidia's GTX 460, which made a splash in both 768MB and 1GB models at similar price points in July.
These 6000-series cards, which were code-named "Barts" during their development, institute a number of improvements designed to both build on innovations from AMD's 5000 series (which launched in fall of 2009) and challenge Nvidia's own technologies.

This has not meant a die shrink: The 6000-series cards are still based on 40nm process technology, but they have been rearchitectured to use approximately 25 percent less silicon.

Video quality enhancements in the 6000 series include improved tessellation;
a revamped anisotropic filtering algorithm for smoothing out particularly noisy textures; and morphological anti-aliasing, a post-processing filtering technique accelerated with DirectCompute. Unified Video Decoder 3 also boosts acceleration for MPEG-2 bitstream, MPEG-4 Part 2, and Multi-View Codec (MVC).

ATI Stream, the 5000 series' GPGPU technology, is not gone, but it has been renamed AMD Accelerated Parallel Processing.
In addition, the cards also offer an updated array of output ports. Whereas the 5000-series cards sported two DVI, one HDMI, and DisplayPort,
the 6000 series replaces the last with two Mini DisplayPort 1.2 jacks,
which will let the user connect multiple monitors to the cards by way of daisy-chaining or specially designed hubs.
The Radeon HD 6870 is the higher-end model, offering 2 teraflops of compute power, a core clock speed of 900 MHz, and 1,120 stream processors; it requires two six-pin power connector, and has a TDP of 151 watts. The Radeon HD 6850, on the other hand, boasts 1.5 teraflops of compute power, a core clock speed of 775 MHz, and 960 stream processors, and with a TDP of 127 watts requires only one extra power connector.

Radeon HD 6900 Series

The high-end "Cayman" architecture used by the Radeon HD 6900 series is a little different to that of the Barts, which debuted with the Radeon HD 6870 and HD 6850 graphics cards. The Barts variant used the same VLIW5 configuration as the Radeon HD 5000 series, which features SIMD units with 4 simple and 1 complex stream processing unit.
The Radeon HD 6900 series on the other hand adopts a VLIW4 configuration, which features stream processing units arranged in groups of four along with general purpose registers. Although the four have equal capabilities, two out of four of these (occupying 3 and 4 issue slots) are assigned with some special functions. AMD claims that VLIW4 configuration gives similar computational power as VLIW5, with 10% reduction in die area.

 
The Cayman GPUs feature a greater level of parallelization when compared to the Evergreen/Cypress architecture used by the Radeon HD 5800 series. The Barts GPUs sit somewhere in the middle, as they were a step up from Cypress in assigning individual dispatch processors for each of the two SIMD Engine blocks.


The Cayman GPUs take things a step further with dual GPEs (Graphics Processing Engines) and assigning each to an SIMD engine block. What this means is that the Cayman architecture* now features two physical tessellation units whereas Barts only featured a single tessellation unit with improved efficiency when compared to the Radeon HD 5800 series as claimed by AMD.
In addition, the Cayman architecture also features reworked render backends consisting of 128 Z/Stencil ROPs, and 32 color ROPs, with up to 2x faster 16-bit integer operations and 2-4x faster 32-bit floating point operations.


Radeon HD 6970  

The Radeon HD 6970 measures 27cm long (10.6 in), the typical length for today’s high-end graphics cards. For example, the old Radeon HD 4870 X2 graphics card measured 28cm long, as did the more recent Radeon HD 5870. As its predecessor, the Radeon HD 6970 GPU has been fabricated using the 40nm process, yet AMD has squeezed in 486 million more transistors and as a result the die size has increased by 16%. The GPU core is clocked at 880MHz, 3.5% higher than the Radeon HD 5870, while the GDDR5 memory also operates slightly faster at 1375MHz. Pairing that frequency with a 256-bit wide memory bus gives the Radeon HD 6970 176GB/s of theoretical bandwidth, a 14.5% advantange over the HD 5870.
Cooling the "Cayman XT" GPU is a fairly large aluminum vapor chamber heatsink made up of 39 fins measuring 13.5cm long, 6.5cm wide, and 2.5cm tall. The vapor chamber design was first implemented in the Radeon HD 5970 and has recently also been adopted by Nvidia with their GeForce GTX 580 and GTX 570 graphics cards. Finally, cooling this heatsink is a 75x20mm blower fan that draws air in from within the case and pushes it out through the back. 


Naturally, the Radeon HD 6970 supports Crossfire and therefore in the standard position we find a pair of connectors for bridging two or more cards together. The only other connectors are on the I/O panel. Our AMD reference sample featured two dual DL-DVI connectors, a single HDMI 1.4a port, and two mini-DisplayPort 1.2 sockets.
It's worth noting that all Radeon HD 6970 graphics cards can support a max resolution of 2560x1600 on up to three monitors. With multi-stream hub using the mini-DisplayPort 1.2 sockets, the card can power up to six monitors.
