Video channel on November 30, Radeon HD series receives the 6800 A card's tradition, and the audio-visual are many enhancements, such as support for DisplayPort 1.2 and single-card 6 screen output, HDMI output, support 1.4a UVD3 video decoding and Blu-ray playback, 3D is currently the most advanced multimedia solution, but because the schema of the Gulf, the Radeon HD 5000 series users probably can only be closed.

Radeon HD 6800 chip integrates third-generation video processor UVD 3.0 (UVD3), in the first two generations on the basis of not only increases the entropy decoding of MPEG-2 format (Entropy Decode), MPEG-4 Part2 DivX/XviD decoding, also supports the playback of Blu-ray 3D stereo programs required MPEG4-MVC decoding.

Although the Radeon HD 5000 series can simultaneously decode two 40Mbps maximum bitrate 1080p Full HD video (Blu-ray 3D another prerequisite), although MPEG4-MVC encoding format is still based on H.264, but MPEG4-AVC decode sometimes need to take into account the two video streams synchronization problem, otherwise impossible to reach the stereo effect. In other words, the Radeon HD 5000 series hardware lack guarantee two video streams synchronization of basic conditions, the nature are unable to support 3D stereo effect.

Of course, from software to control two video streams synchronization is possible, but because there is insufficient, UVD2 itself change the BIOS, drivers for Radeon HD 5000 series supports Blu-ray 3D play is certainly not a small amount of work, but also as a Radeon HD series 6000 and lose a selling point.

All in all Radeon HD 5000 series with Blu-ray 3D's fate depends on what attitude the AMD, but so far we haven't heard about AMD have such plans. Look forward to the catalyst can surprise.

In addition, AMD claims Radeon HD 6800 series you can get the HQV 2.0 test 198 minutes, than the last generation of slightly higher (Radeon HD 5570 can be 189 minutes), distance 210 minutes only full marks a step away. ■
