    What decoding acceleration hardware are you referring to? What component built with the HD2900XT is being enabled (in the next cat release) that will help decode acceleration? Or is this software driven (which depends on cpu power). The reason why I ask is that you clearly stated
    If this is true then what decoding acceleration are you talking about? You clearly state that HD 2900Xt needs to be paried with a HD video capable CPU :roll: BTW, what are video capable cpus? Are you refering to what's currently in the market or something AMD has plans to release?

    I think the accelerator Dave mentioned would be the same as the one in the R5xx series (X1xxx) that uses the shader processor to do video acceleration tasks. However, since the shader core of R5xx are different to that of the R6xx core, the software that was programmed to work with R5xx on the old CAT CCC will not work with the R600 core. That means a new driver is needed for the R600 to enable the video acceleration on its shader processor.

    It is just my point of view on this, I am also not a person experted in the field too, just a noob here :wink: Hope it might help...

    Edit: typo as usual...

    I would assume he means the current things AVIVO offloads from the CPU. UVD just offloads MORE things.

    IE - this is a major reason the R580 is doing better than the R600 in offloading from the CPU when playing HD content. AVIVO hardware acceleration is enabled for the R580 in current drivers but it is not enabled for the R600 in current drivers.

    I guess that justs proves that your expertise < mine since I have a fully silent HTPC with an 2900xt and a 1200w powersupply. And considering I can game at full 1080p with high end performance, while YOU have to run to the other room to play on your "dedicated" gaming machine on your smaller lcd... well enough said.

    Celeron? I wonder if you can even read. I'm certainly not running a celeron, I'm running a 6600 duo overclocked to 3ghz, oh yeah, in my silent HTPC.

    If you need any tips on achieving higher end pc integrations give me a call sometime.

    Btw, SB. Your PS about UVD on the Sapphire box... it's called spindoctoring and no, it's not the same thing as having actual UVD.

    Current technology DOES allow this, my setup is an example.

    I have a completely silent (for all intents and purposes) setup. Granted I'm using Watercooling, but that is "current" technology and is readily available to consumers today.

    I'm extremely pleased with my HTPC setup, so much so that I don't use any other computers for gaming or anything else. This one PC is about as high end as you can get without going to an Extreme processor. And Crossfire is coming IF I decide to stick with the 2900.

    The UVD issue is the only thing holding me back from going further. As an HTPC (which was the primary purpose of this build, along with gaming) having the UVD promised on the product packaging is a major feature and very important to overall system performance during HD playback.

    Thanks for the information. With 8.38 RC7 drivers Hardware acceleration enabled from PowerDVD Ultra caused this with Wolf Creek HD-DVD movie (H.264):

    [​IMG]

    Looking forward to test with Catalyst 7.5 drivers.

    Now we just need to get some of the big hardware sites to get their facts correct regarding R600 and UVD. Here is a direct quote from AMD:

    "UVD is available for RV630 and RV610. UVD is meant to enable HD playback for entry level and mainstream PCs, which often do not have the system power to decode HD content from blu-ray or HD-DVD. The HD2900 XT is meant for high end gaming and for that target, it is common to have an average system performance. The ATI Radeon HD 2900 is bursting with shader power and will assist decode in the same way our previous generation did - the advantages of the UVD block in video performance are not required here."

    "HD decode acceleration will be enabled in the upcoming Catalyst release (7.5), which should become available in the next few days."

    Right on the money, but you don't even have to use a sound proofed case if you make the right case choice. I'm using the Zalman 160xt (the LCD is superflous, the 160 case would work as well).

    You should also ask this question to those still using AGP! :wink:

    Interesting considering I have a virtually silent PC that is capable of gaming in the home theater room. With a fanless PSU, and Core 2 Duo also cooled with no fan. In a case with sound deadening panels and suspended HD's so that I don't hear them. There is a single 120 mm fan cooling the entire case and components.

    My friend tried out his 8800 GTX in said case. And you know what? While the case made virtually no noise in that room previously, with that 8800 GTX it was freaking loud.

    I have yet to find a single 1200 watt powersupply that doesn't sound like a jet engine in the home theater room. Hell, I've yet to find a 600 watt powersupply that doesn't sound noisy in that room. Enough so that you can hear it over the quiet parts of some movies.

    I'm going to assume that you use your case in a room with high ambient noise, rather than assuming you can't hear anything. :grin: Then again maybe, I just have really good hearing. :wink:

    My apologies on the celeron comment in regards to you, it was cadavega that was pairing a HD 2900 XT with a celeron.

    Regards,
    SB

    First, you assume that everyone has thier pc directly in thier theatre...I do not. I have an "electrical room" for that sort of stuff, soundproofed, so any noise disappears when I close the door. Pretty basic, if you ask me. Think about it...I just dropped 3g's on videocards...you can bet I don't cut corners because of financial constraints.

    And yes, a celeron...and quite obviously you have no idea what AMD's Xilleon is, nor have you got much experience with HD content, nor have you ever published any either. A good UVD has it's own processor, as the Xilleon does, and this means that inclusion of a seperate cpu is not nessecary...

    And please note that the Xilleon set top boxes utilize a 300mhz MIPS cpu to push 1080p, and I bet this here celery has more gusto than that.

    Please save your insults for when you know what it is that you talk about. Had the 2900XT had HARDWARE DECODING, pretty much any cpu would do...all it then does is push data to the vidcard, and all processing happens there. That's what a UVD does...

    And, yes, my Sapphire boxes states it uses UVD technology to process HD content. pretty straight forward, and they've got some explaining to do.

    I wonder if i got to the pc store today, will I find another box labelled jsut like this?:lol: Someone needs to make some phonecalls, becasue these cards WERE NOT READY FOR RELEASE.:lol:

    I find my Zalman 480 dead silent but then again. that's not 600Watt...

    Wow, I thought this thread was about the RV630/RV610, I guess I was wrong.

    It all applies...any of teh mentioned issues regarding UVd and HD decoding should not be an issue when using 630/610. This is an importnat feature that these cards have over the high-end HD2900XT...all in all making them a very well-rounded pc video devices.

    My aptly named P&C 750 Silencer is inaudible in my case.

    They already have a nice feature over the 2900, a lower price.

    Let's face it. The reason why UVD is missing from the 2900 has nothing to do with marketing or "high end card users don't need it" logic.

    As for the feature being a good addition for the lower end lines, of course! But name me one major product line that REMOVES high end features at the top and puts them on the bottom....

    Well I guess this is a new trend huh!?

    I want my CPU cycles back that UVD promised me with this card :)

    Well it's not in the 8.38 rc7 drivers so I find it doubtful. At least it sure isn't seen by Cyberlink PowerDVD.

    Apology accepted.

    My room has no ambient noise at all if I turn off the AC :). And trust me this setup is completely silent. Well, completely silent unless you want to put your ear up to the fans on the case (which thanks to the Reserator 2 only need to run at 20% speed to cool the rest of the components).

    As for the 1200 watt psu noise comment, I agree. Up until now there really were no PSU's that I knew of either that were quiet. The Thermaltake Toughpower 1200 has changed that. This PSU is really amazing. The fan is 140mm and runs virtually silently at full load.

    Keep in mind haivng this kind of quiet HTPC case with high end hardware isn't cheap. It requires things like water cooling and more expensive PSU's. Although I'd bet that a more affordable one than I've built could be put together as well.

    Uhm.. You do realize that the EXACT SAME THING is true for G80? The reason is simply that the new video core R&Ds wasn't finished early enough to be in either G80 or R600. I fail to see what's so extraordinary there. Now, if the high-end refreshes didn't have the new video cores, that'd be another story - but they obviously will.

    The information on certain product boxes and the data that was on AMD's website is clearly wrong, unacceptable even, and I'm not trying to defend that. I think some people are massively overreacting though. In practice, UNLESS you are on a super-low-end CPU (remember, this is the same hardware as on R5xx, it still accelerates part of the process), the ONLY effect this will have is higher power consumption when playing videos. Everything else will be equal, including image quality. While this might matter for some people, even those with 2900XTs, I would at least hope that it isn't the primary consideration of anyone buying those cards...
