Meet the Barts

When the 6800 Barts cards were released, we noted some differences from the 5800 series graphics cards. Gone is the ATI moniker, replaced by AMD branding, which shouldn’t really come as a surprise since ATI was purchased by the chip giant several years ago. The other difference was the naming conventions for the new 6000 series cards. The 6800 cards became the new "lower end" of the premium gaming cards rather than the flagship ones.

The second major difference here is the naming conventions for the cards. These 6800 cards are based on the Barts core, the "low end" of the new premium gaming cards. It seems that AMD has decided to separate the model lineup with a more granular setup than the 5000 series, thus avoiding any actual "successor" comparisons. This means that the 6870 is in fact not the direct successor to the 5870.

Aside from the specifications, another difference is the available physical outputs: the HD 6870 has two DVI, one HDMI and two mini-DisplayPort outputs, allowing a wide choice of monitor configurations to be used. With the release of the DisplayPort v1.2 drivers, it will be possible to daisy chain several DisplayPort v1.2 monitors from each DisplayPort output.

Below is a bit more detail for the stock 6870 model specifications:

Another feature now provided with this new generation of cards is 3D Stereoscopic support. Nvidia has already offered 3D technology and now AMD is following suit. AMD has partnered with 3D middleware vendors such as Dynamic Digital Depth and iZ3D to offer stereoscopic 3D gaming experiences with these 6800 series cards. AMD’s solution differs from Nvidia in that the former uses 3rd party software, whereas the latter provides driver-level implementation. The main similarities, however, are that glasses and a 120Hz display is required for the technologies, but there are very few 3D-capable PC monitors currently on the market.

Certainly the appeal and immersivity of 3D gaming is tantalizing, but at this point the technology and hardware required is fairly cost prohibitive for the most part, not to mention the phenomenal graphics horsepower required to maintain reasonable framerates in modern games. That being said, the differences and successes of 3D technology are beyond the scope of this particular review, and 3D gaming is still experiencing teething problems, but it will be interesting to keep a close eye on developments as they move forward.

The last new feature incorporated by the 6000 series cards relates to bitstreaming audio. Until now, a Home Theater HD card sound card was needed to process these lossless audio formats. Typically this card required a cable routing the video signal from the graphics adapter to the sound card. The sound card then combined the digital audio sound track with the video signal and sent the matched up signals to the monitor via an HDMI cable. With a 6800 Series video card, all you need to do is install the card into your motherboard and connect it to your receiver with an HDMI cable, thus eliminating the need for a separate sound card and making for a more economical setup.

Below is a GPU-Z image of the Sapphire Radeon 6870 Vapor-X that show the particulars. As you can see, the card comes with stock clocks of 900MHz/1050MHz out of the box.

Let’s discuss AMD Eyefinity next.
