Apart from gaming performance, the new AMD Radeon HD 6000 Series supports several interesting features.UVD3, HDMI 1.4a, DisplayPort 1.2
Radeon HD 6000 Series GPUs are equipped with UVD3 (Universal Video Decoder, 3rd generation)
that can decode MPEG-4 MVC
(Multi-View Codec) (Blu-ray 3D codec) and MPEG-4 Part 2 codec (DivX
), and finally supports VLD for MPEG-2
(has been advertised for a long time, but never been implemented; AMD now officially admitted that it is not implemented in UVD/UVD2!).
HD 6800 Series supports the following display outputs:
- HDMI 1.4a x 1
- Mini DisplayPort 1.2 x 2
- Dual-Link DVI x 1
- Single-Link DVI x 1
With the HDMI 1.4a port HD 6800 Series supports Blu-ray 3D, 3D broadcast and 720p stereoscopic 3D gaming with a HDMI 1.4a AVR and a HDMI 1.4a HDTV/projector. DP 1.2 supports the bandwidth of 17.28 Gb/s (much higher than HDMI 1.4a) and multiple audio/video streams, that improves AMD EyeFinity of HD 5000 Series.
AMD EyeFinity Technology
DisplayPort 1.2 supports:
- 21.6 Gbps (17.28 Gb/s video) bandwidth (much higher than HDMI and dual-link DVI)
- Multiple video streams throuth a single connector
This means that, for example, up to four 1920x1200@60Hz displays
are supported over a single DP connector
with a MST (Multi-Stream Transport)
hub (DP 1.2 versions expected in 2011) or daisy-chain
. Thus the reference HD 6800 card, without a special "EyeFinity6" edition, supports up to 6 displays
(the GPU has 6 graphics controllers like the previous Cypress GPU). Some possible configurations are:

is the new name of AMD's visual acceleration technology. The basic ingredients are
- AMD Accelerated Parallel Processing (APP) Technology (formerly ATI Stream)
mainly applied to video playback, video transcoding and gaming. So they are basically former ATI Avivo Technology, ATI Stream Technology applied to transcoding, and application to gaming such as physics effects and Artificial Intelligence (AI).

(a nice summary)
So we can now play stereoscopic 3D games with a Radeon HD 6800 Series graphics card and a HDMI 1.4a display (via DDD and iZ3D’s stereoscopic gaming drivers), but only up to 720p@60Hz (per eye)
due to HDMI 1.4a limitation. We will be able to play stereoscopic 3D games at 1080p@60Hz (per eye)
via DisplayPort 1.2 when monitor vendors begin incorporating DisplayPort 1.2 sometime next year (but it's PC monitors that support DisplayPort; we won't see a CE displays supporting DisplayPort in a foreseeable future).AMD's White Papers
