For those interested in a reminder, the AMD HD 6000 series will be powered by the same manufacturing process of 40 nm as the H-series GPU 5000. Is supposed to be superior in all respects to the ancestors and intends to give Fermi NVIDIA cards have a hard time. The first two models set to debut are the HD 6850 and HD 6870, which are fed by the graphics processing unit Barts. The actual clock speeds of these input plates have been kept secret until now, but it seems that are no longer hidden. The Radeon HD 6850 has the Barts operating at 725 MHz, while the 1 GB of GDDR5 VRAM is set at 4,000 MHz. The HD 6870 is of course faster, GPU and memory clocks of 900 MHz and 4,200 MHz, respectively. Both have support for DirectX 11 and come with a memory interface of 256 bits, a TDP of 150W CrossFire and multiple video outputs, i.e., two DVI, an HDMI 1.4 port and two mini DisplayPort 1.2 connector. The Sapphire HD 6850 was matched with a price of $ 265.7, while the HD 6870 was included at the equivalent of $ 358.5.
After the Radeon HD 6850 and HD 6870 official, it's now all manufacturers to begin offering different versions, or not elsewhere. Exactly, Sapphire Radeon HD 6850 offers a modified cooling system with a reworked from the original, by cons, nothing is known about the remaining changes. The information will be available with the official AMD announced about the new Radeon HD 6850 and 6870. Radeon HD 6870 cards will initially be available only as a reference design and only later appear in their own versions of the partner. This we have seen already at the Radeon HD 5870 models Sun A first picture of a Sapphire Radeon HD 6870 on a label corresponds to the reference design from AMD.
The Radeon HD 6850 cards the other hand, seems to regard the cooler directly to your own design to be carried by all manufacturers, at least in the form and coverage and is begging here on the reference design. So you find a picture of the Sapphire card from the radial reference design HD 6850 differs significantly. The card also has a blue PCB, indicating a self-production of Sapphire. Whether it is the model already a Toxic version is not clear. So far there is no information about higher clock speeds for the models. Meanwhile, just over a year has passed and how AMD tells one has so far released over 25 million DirectX 11 GPUs, the Radeon HD 5000 family in the market. The manufacturer's stated goal was to secure the achieved market leadership, not just expand.
In fact, in terms of market shares, the Radeon HD 5000 family of AMD certainly a great success. However, this was also due to the fact that NVIDIA late March its own DirectX 11 implementation in the form of the GTX 480 could imagine. Since the competitor with the high-priced products reacted so late, AMD had to fear for months no real competition.

Configuration
AMD's answer to the extremely popular GeForce GTX 460 could not be realized, of course, permanent price reductions over. Barts Pro and XT were the names of the secret weapon for many weeks by the Web haunt some. Originally conceived as a Plan A was being considered, send the GPUs in the Radeon HD 6750 and HD 6770 to the market. There was also a plan B, which is carried out officially today. AMD releases the first two models of Northern-Iceland-family as the Radeon HD 6850 and Radeon HD 6870 into the market and makes no secret of the fact that immediate goal is that the GeForce GTX 460 with 768 - and 1024-MB of main memory.
Since most of the core features already at the launch of the HD 6850 & HD have listed in 6870, we want to take on this rather short. All new graphics cards with the 40 nanometer chip Barts are able to support DirectX 11 and also direct 11 instructions, 3D stereoscopic displays (HD3D) and up to 7 monitors per graphics card. The Barts GPUs will replace it once the two models of Radeon HD 5830 and HD 5850th Important: The new GPUs are cheaper to manufacture than the previous two, which AMD is able to work with other prizes. But the new GPUs will of course be much faster and connect with a host of new features to.
Both the HIS Radeon HD 6870 and the Sapphire Radeon HD 6870 with the reference cooler from AMD and are equipped to distinguish their respective labels only. The rest of the components, the reference, and the 1120 stream processors clocked at 900 MHz and get 1 GB of GDDR5 with 4,200 MHz cache deployed as. The user can monitor via 2 DVI, 2 mini DisplayPort 1.2, or 1 HDMI 1.4a connection with the connect a PC.
Performance
The Sapphire Radeon HD 6850 we have one of the first graphics cards based on AMD's new DirectX 11 generation in the test. Although the board operates according to the manufacturer AMD's recommendation for the chip at 775 MHz and 4000 MHz effective for the 1.0 gigabytes of GDDR5 video memory. Sapphire's HD 6850 but missed its own cooler, which - was so much anticipated - an improvement over AMD's product.
These included Radeon HD 6850 on our graphics card test system as well as expected as soon as the reference model of AMD, thus on a level with the Radeon HD 5850 and GeForce GTX 460 with 1.0 GB of video memory. Without smoothing the New else is behind the HD 5850, with a minimum four-time anti-aliasing but front. The biggest difference we can make in the extreme setting 2560x1600 with eight-time anti-aliasing and 16x anisotropic texture filtering: 27.6 to 23.1 frames per second, the Radeon HD 6850 in the test a full 20 percent faster than the previous model and also as the GTX 460 1 , 0 GB.
In the Sapphire Radeon HD 6850 we had noticed that the card between five and ten percent faster than expected from AMD sent pattern. A little research told us later GPU-Z the author of the problem: the video card works with 1,120 stream processors, so a fully extended Barts (XT) graphics chip - the correct configuration would be 960 ALUs. The clock speeds, however, are set correctly to 775, respectively 2000 MHz.
