    False information in the articles: No UVD in R600

    I've been testing HD-DVD playback with Xbox 360's HD-DVD drive and latest version of Cyberlink's PowerDVD which includes support to Radeon X2000 series hardware decoding (http://www.cyberlink.com/multi/downl...7_112_ENU.html)

    I have two HD-DVD movies here, Serenity with VC-1 codec and Wolf Creek with MPEG-4 AVC (H.264) codec. With both movies there are absolutely no benefit from Radeon HD 2900 XT's hardware acceleration feature in PowerDVD settings. For example with Core 2 Duo E4300 average CPU load remains at 72 % with H.264 movie (GeForce 8600 GTS 14 %).

    Yesterday AMD's Dave Baumann posted this to B3D Forums which explains why:

    "HD 2900 does not have UVD; it'll be paried with HD video capable CPU's."

    http://forum.beyond3d.com/showthread...69#post1009569

    ---

    The weird thing is that the biggest hardware sites in the world are writing in their Radeon HD 2900 XT articles that R600 supports UVD:


    "The R600 Video Decode Pipeline: UVD"

    "AMD is one upping NVIDIA this time around, as their UVD (Unified Video Decode) architecture is also capable of decoding VLC bitstreams on all three HD media codecs."

    (Although they tested the feature..)

    "Either way, the best way to figure out what's going on is to take a look at performance and see if there really is any advantage to R600 over G86. Unfortunately, try as we might, we could not get UVD to work with the current drivers provided by AMD and the PowerDVD release that is supposed to enable the hardware acceleration on HD 2000 series parts. We will have to take a second look at hardware decode when AMD and CyberLink or Intervideo get their software in order."

    Anandtech: http://www.anandtech.com/video/showdoc.aspx?i=2988&p=13


    "This new processor is called a UVD for Unified Video Decoder. While it is a processor unto itself, the silicon is actually a part of R600, much like how the 2D and 3D engines are internalized."

    Tom's Hardware: http://www.tomshardware.com/2007/05/...ti/page16.html


    "All '6-family products and the GPUs that drive them contain a new video decoder block, which AMD worked with Tensilica to build, called UVD, or Unified Video Decoder"

    "Every SKU of this new generation of Radeon could perform (almost) full CPU offload acceleration for video playback for all three current optical disc formats."

    Beyond3D: http://www.beyond3d.com/content/reviews/16/11


    "All of the new members of the Radeon HD 2000 family of GPUs feature a new AVIVO HD video engine with better performance and more functionality than the version found in the Radeon X1K family of products."

    "The new AVIVO HD engine features AMD's Universal Video Decoder technology, which basically offloads every major aspect of HD video processing from the host CPU and performs the functions on the GPU."

    HotHardware: http://www.hothardware.com/articles/...rrived/?page=8


    "In addition to all of the new graphics goodness, the R600 brings with it some important new capabilities for high-definition displays and video playback. The most prominent among them is a brand-new video processor AMD has dubbed the UVD, for universal video decoder. The UVD is a dedicated processor with its own instruction and data caches, and it can accelerate key stages of the decompression and playback of HD video formats for both HD-DVD and Blu-ray, including H.264 and VC-1."

    The Tech Report: http://www.techreport.com/reviews/20...t/index.x?pg=9

    ---

    Some sites like Hexus and HardOCP are writing it correct: R600 doesn't include UVD.

    Since dave makes it clear there is no UVD, no one can argue that point. However you said there was no performance change, and that is due to driver support.

    ahmad, propably so. RV630 and RV610 will fully support UVD.

    Good. I hope they fix this R600 flop soon with R650.

    Here we were told so by the guys at hardware.fr right in their 5/15 review there http://www.hardware.fr/articles/671-...d-2900-xt.html
    They are usually doing a very decent job in their reviews, this being particularly true for their lcd display reviews, unfortunately for most of the XS crew it's in French.

    R600 have UVD. It can only not be ativated within the drivers.

    8800 also doesn´t have the video processor of the 8600.....

    so AMD's Dave Baumann doesn't know what he's talking about?

    It's not AMD but hardware sites which have misunderstood R600's features.

    If it doesn't have UVD then it's not just hardware sites that got it wrong but GeCube etc, after all they put it on the box.

    If it does then Dave needs to stop smoking whatever he's smoking.

    ASUS websites are also full of b*ll$h*t about their own products (see P5N32-E Plus, which was based on nForce 650i according to ASUS technician). Sadly misinformation is very widespread in computer business.
    I don't know how it is in more advanced countries but here in Poland it's common for retailers to sell pre-built rigs with 4.2GHz CPU's (they say 2.4GHz dueal core Pentium D is 4.2GHz); that's only one example.

    Does it matter whether R600 has UVD? If you have a R600 in your system, the chances are you'll have a high end CPU to do the video decoding, or at least high end enough to be doing video decoding on the CPU. And who really wants to use R600 to decode when your CPU uses less power to decode the video. I'm sure there are still some video acceleration on the R600, but just not as good as UVD like there is on the RV610/630.

    You're saying one of ATi/AMD's employees don't know what the R600 has?

    Well, I'll say this much...my box says UVD...and if it doesn't work, someone is geting a lawsuit for false advertizing! They either provide what the box says is included, or they refund all buyers...AMD could be in a world of hurt over this.

    AMD won't be the ones in trouble...

    It'll be the vendors.

    True that. ONly HIS box has this on it, Sapphire does not. Realistically, there is a way out of this, but someone still gonna have to pay for the lawyer, or they lose...

    AMD says in HD2000 series press relase, 65nm products only for UVD:

    The ATI Radeon HD 2600 series, ATI Radeon HD 2400 series, and all ATI Mobility Radeon HD 2000 series products include AMD’s new Unified Video Decoder (UVD) technology for high-fidelity HD multimedia playback.


    http://www.amd.com/us-en/Corporate/V...117414,00.html


    HIS didn't listen, obviously, and I want a refund. Methinks many boxes will get a flat black sticker on them!

    I think a few other partners boxes say this too.

    GeCube for example.

    Interesting.

    To be honest, I actually thought that the xilleon engine was on these cards, never even gave it a second thought after confirming HDMI output...so I seriuosly got screwed on this. Just dumped $600 on internal blu-ray player...for nothing! I could have got much lesser card for my HTPC...

    You have no reason not to think it was on the card. After all, it specifically stated it on the box. Of course, AMD/ATi isn't to blame, it's the vendors who obviously couldn't read. False advertising is a pain in the...well...you already know.

    I'm just curious on if there will ever be any good news for this card.

    Man that sucks... Then again by the time I get a HD-DVD drive or Blu-Ray drive I would of already upgraded to a better card anyways.

    Totally thought that UVD was in the R600's. Oh well I still am enjoying my card.
