Sapphire Radeon 6770 Vapor-X
Features and Specifications
As you can see in AMD’s product strategy below, their Barts cards are positioned at the bottom of the performance rung, but notice the gap at the bottom where the 5770 moves completely ahead with no replacement part noted. That’s because this 6770 is essentially a rebadged 5770 with the addition of HDMI 1.4a suport.
Going strictly on price alone, the Radeon 6790, not the 6770, is actually the competitor to Nvidia’s GTX 550 Ti, with those two cards each costing about $150. The Sapphire 6770 Vapor-X costs about $15 less, so it’s not far off the price, and it remains to be seen if the small drop is price corresponds to the available graphics horsepower.
In terms of features, the 6770 Vapor-X continues what we’ve seen on the Barts cards, including 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. The 6770 Vapor-X simply isn’t designed to carry that type of gaming load, so don’t expect these premium features to run smoothly on a $135 card.
The last 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 6770 Vapor-X that show the particulars. The card comes with clocks of 860MHz/1200MHz out of the box (a very slight overclock of 10MHz), 1GB of GDDR5, and 800 Stream Processors.
