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 Xvid), 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 [email protected] 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:






AMD EyeSpeed Technology

AMD EyeSpeed Technology is the new name of AMD's visual acceleration technology. The basic ingredients are
  • UVD3
  • 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).




AMD HD3D Technology


- AMD HD3D Technology (AMD's official page)

- ATI to use HDMI 1.4a, DisplayPort 1.2 open source 3D standard (Neoseeker) (an older article)

- 3D Platform Wars: NVIDIA 3D Vision vs AMD HD3D vs 3D HDTV (BenchmarkReviews) (the longest article)

- 3D Gaming (Legit Reviews)

- 3Stereoscopic 3D With AMD’s HD3D (Tom's Hardware) (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 [email protected] (per eye) due to HDMI 1.4a limitation. We will be able to play stereoscopic 3D games at [email protected] (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).

- HD 6990 (Antilles) (Cayman x 2) will be released in Q4 2010.

- HD 6700 Series is absent? (HD 5700 Series continues.)

- HD 6600 Series, HD 6500 Series and HD 6350 will be released in Q1 2011.

"6800s" are really 6700s. This is from the Guru3D review of 6850 & 6870:


"...what we have been looking at today should have really been labeled Series 6700 as the fastest products, which you'd expect to be placed in the 6800 series, still need to be released."

Yup, AMD's original plan was (no official statement, of course):


Barts -> HD 6700

Cayman -> HD 6800

Antilles (Cayman x 2) -> HD 6900.


As everybody agrees, these are pretty natural namings. However now:


No HD 6700

Barts -> HD 6800

Cayman -> HD 6950/6970

Antilles (Cayman x 2) -> HD 6990.


A rumor was that HD 5700 Series would be rebranded as HD 6700, but this won't happen, according to AMD's slide .


There are several guesses why Barts became HD 6800. AMD said, AMD wanted HD #800 Series to stay in the $150-$250 segment, HD 5800 Series was not normal [too pricey, higher performance], HD 6800 Series just went back to the normal track ( this slide ).

If you have a 5xxx card already (I have a 5670 for HTPC use) is there any reason to consider upgrading to the 6xxx? The 3D option is nice but I don't have a 3D TV and don't see getting one anytime soon, would that be the only real upgrade from an HTPC standpoint?

Well then, I don't see a reason to upgrade the graphics. UVD3's support for Divx, Xvid, VLD for MPEG-2 is unimportant, and all the video post-processing tasks are done by generic stream processors (HD 5670 has plenty of them), for which only the driver's maturity is important.

An interesting rumor:

VPP: AMD Prepares New Video Processing Engine

Quote:
The software is known under codename "VPP" i.e. Video Power Pack [we also heard "Video Processing Pack" being mentioned, probably a deliberate distraction in an order to control who leaked the information]. Primary goal for VPP is to significantly improve video quality and video transcoding, enhancing the consumer experience by improving the already high level of video playback and avoid errors.


The problem AMD had with AVIVO HD software was the unpleasant fact that AVIVO is old, hard-coded software that could not properly utilize the current generation of DirectX 11 hardware, often producing inexplicable errors. Thus, we were not surprised to hear that AMD is working on complete rework of current Catalyst driver stack, as AMD was unable to properly address issues they were facing internally. Read - legacy software was also to blame for the poor scalability of AMD Radeon cards when compared to their competition, i.e. how two $200 cards would outperform two AMD's $400 cards in their respective multi-GPU configurations.


However, all of that is now history - it looks like Rick Bergman received open hands to fix everything that was wrong with AMD's GPU division, and the company is finally dedicating financial and human resources to make that happen. We won't go into exact details how we learned of experiences that some AMD engineers faced in order to bring great features to the market, busy fighting with the engineers from older-school which shot their chance of fame long time ago.


In any case, that "old school" lost the war and now ex-ATI folk are making sure Fusion gets executed properly.

I currently own a Radeon 4890 OC (Vapor-x). It's quiet, fast and altogether solid but it doesn't support bitstreaming. My only complaint is the whole realtek vs ati HDMI driver thing.


1. Between ATI UVD3 and Nvidia VP4 which provides the best picture quality for HTPC users?


2. Who has the better bitstreaming support between ATI and Nvidia?


3. If you were me would you buy a 6870 or the GTX460 for 50/50 gaming HTPC use?


HTPC will connect through a Pioneer 1019 to a Benq W5000 projector.

"For a consumer interested in the 3D ecosystem, the GT 430 is definitely a better option than the similarly priced HD 5570. The GT 430 also brings the latest and greatest of VP4 to the table. This includes full MVC decode acceleration enabling hassle free playback of 3D Blu-Rays. The GPU also scored a perfect 100% in our media streamer test suite, and had no issues with bitstreaming HD audio of any kind. Flash acceleration works very well and sites such as YouTube and Hulu benefit handsomely. Silverlight also utilizes GPU acceleration. Netflix is able to take advantage of the same."

UVD3 is completely equivalent to VP4. For PQ (for SD), HQV 2.0 scores may be helpful (supplied by AMD
; kitguru for HD 6870, xbit-labs for GTX 460). Guru of 3D gave detailed analysis of gaming performance (HD 6870 > HD 6850 > GTX 460).

Is this a pure software/driver upgrade Do you think it can work on older hardware (read HD 4xxx+), or is it only availble for new hardware (read 6xxx+/Fusion)?

It's just about the driver. If the story is true, then the driver (video playback part) will be optimized for newer DX11 GPUs (i.e. 5000/6000). Of course the developers will take older hardware into account.

Has anyone confirmed it actually does VLD for MPEG-2? Remember this was promised for the 5xxx series too and was never delivered - and it does matter for those of us who watch HD caps with low-powered cpus.
