2900 XT lacks a UVD

[Wreckage]

EDIT: Looks like the Tech Report is all over this issue.

I actually read about this over on the Rage3D forums, I thought maybe someone here with a HD2900 or who might "know" more about it could look into it.

HD 2900 does not have UVD; it'll be paried with HD video capable CPU's. The drivers used in that test don't yet have decode acceleration enabled either, first revision of that comes with 8.38.

It is a pity the HD2900XT didnt add UVD engine but there is no consumer will choose Sempron processor to match 2900XT.

Looks like there will be one on the 2400/2600.

That's pretty sad as they are marketing it as the hidef video card. :roll:

If only Anandtech could lack a Wreckage.

So what is an UVD and does the 8800gtx have one?

So you are saying it's a good thing that it does not have one and no one needs to know it's missing. :roll:

I suppose you would rather this kind of information was suppressed. Bury you head in the sand.

Nah, you are just bashing a fellow forum member for no reason.

It's hardware video acceleration like purevideo.

 

[ronnn]

But pure video is no better than what ati had, so I assume no

 

[Lord Banshee]

Isn't it a feature which speeds up Blue-Ray and HD-DVD processing.. I would think all other formats are still there as why would ATI get rid of something they had in their previous card.

But lets not forget Nvidia did the same thing with the first series nv40 (6xxx) series came out. Non of the 6800NU,GT,Ultra that used the nv40 chip had purevideo acceleration even though nvidia said it was a feature.

Seeing that i do not know what UVD "really is" is it listed as a feature http://ati.amd.com/products/Radeonhd2900/specs.html ?

It is a pity that they did not include it on the HD2900XT.

The fact that the 8800GTX does not have Purevideo HD changes nothing.

AMD was marketing the HD2900XT for other things besides 3D performance.

Personally, I think that if they were trying to cater to HTPC users with features like HDMI, then they should have included UVD on the HD2900XT.

I think what he is saying is, the only ATi threads you make, are ones that try and make ATi look bad. Which is actually pretty true.

I would think that most HTPC users would be looking for passively cooled or single slot solutions, not dual-slot high-heat producing cards like the 2900XT or 8800GTX.

I tend to agree, which is why I dont care about Purevideo or AVIVO on either solution.

I just dont see the point in pimping a feature like HDMI, when really the only people who need HDMI are the ones running HTPCs.

I guess it's good for people running their PCs on huge 1080P TVs, but that's a very small percentage of the market. Makes sense that I still havent seen a HD2900XT with HDMI.

" As you can see, with UVD and Avivo HD, the Radeon HD 2000 series is capable of handling both the bitstream processing and frequency transform stages for both VC-1 and H.264 playback, whereas the VP2 processor in NVIDIA?s GeForce 8600/8500/8400 is only capable of handling this for high definition movies using the H.264/AVC Codec; when using VC-1, this is handled by the CPU on the GeForce cards.

With UVD handling all decode stages for high definition playback, CPU utilization for high definition playback is just as low as it was for standard definition playback. This is important for those of you with slower CPUs and/or those on notebooks. Without the GPU handling these tasks, CPU utilization for a high bit-rate HD-DVD or Blu-ray disc could be over 70%, even on a fast Core 2 Duo CPU.

In addition, ATI has added custom logic to the Radeon HD 2400 and 2600 for video post-processing capable of performing de-interlacing, up/down scaling, and color correction.

All Radeon HD 2000 series GPUs are HDCP-compliant. In fact, the Radeon HD series is the first line of GPUs to integrate the HDCP encryption keys directly into the ASIC, no external CryptoROM chip is needed. As a result, we?d estimate that all Radeon HD 2000 series cards should support HDCP, regardless of manufacturer. Previously this was often left in the hands of board manufacturers, particularly on lower end cards where board partners didn?t want the added expense of adding HDCP support. All Radeon HD 2000 series cards are also capable of supporting HDCP over dual-link DVI."

Sorry Mom. I corrected it.

I'm not denying that. I try to counter balance the forum. You are a die hard ATI defender, so I don't see the difference. I don't imagine you posting it, for example. Regardless I think it's important and worthy of discussion. Just as the partial Purevideo support in the 6800 needed to be explored.

Well its from dave so its not a rumour or speculatation. But really who needs it when most high end PCs nowadays use dual/quad core CPUs.

Yeah, they reprinted the press release from AMD. They also mention the whole series. No CPU load test were performed. I think they need to clarify their advertising a bit.

 

[tuteja1986]

Dude you know the image quality of H264 decoded by 8600GT is no match for 8800GTX quality. They reduce the quality of decoding by using cheap on board dedicated processor. Thats why the low end ATI HD gpu series will have a dedicated Vidoe processor to.

I think your confusing yourself with h.264 HD acceleration. Quality should be the same really since both employ the same algorithms for e.g de-interlacing etc. Actually, pure video/avivo is literally a special function in the GPU that accelerates those tasks e.g h.264 decoding, hardware acceleration during playback etc. IQ nowadays is pretty similiar as seen by HQV benches.

The only reason the low/mid end cards have these more advanced video processors is because PCs with these GPUs have low end CPUs that could potentially lag/stutter while playback. To offset this, they support HD acceleration that greatly reduce cpu utilization for smooth playback.

just following your example ... what you do to others

and *everyone* is saying you have the credibility of a nvidia fanboy who lives to pick apart AMD video cards


that's all


Hd2900xt also lacks a STD

read the article yourself ;(

"With the GeForce 8500 and 8600 however, NVIDIA has given video enthusiasts a superb mainstream option. With the more powerful VP2 video processor, a bitstream processor, and AES128 decode engine, these new GPUs are offloading virtually all of the compute-intensive elements of Blu-Ray and HD-DVD playback. This allows HTPCs to be built with combo HD-DVD and Blu-Ray drives while avoiding the hefty cooling requirements of a flagship CPU. With today?s drivers, the only difference between the 8800 and 8600 (when it comes to video quality) is HD noise reduction and HD sharpening. With tomorrow?s drivers, who knows?

The 8800 is "picture quality" champion due to HD sharpening and noise reduction. This is particularly important for watching broadcasted HDTV. These quality features are only available on the GF8800 because they are being performed by the GPU shaders."

Yeah, It reminds me of nV40's PVP marketing campaign..

I for one am glad that Wreckage has a hobby, if you can call the somewhat mindless posting of ATI bashing and Nvidia loving posts a hobby

Lately, ATI needs no help looking bad

 

[apoppin]

What ATi?


last i looked it was "all AMD"

 

[ShadowOfMyself]

And here I thought Wreckage looked pretty unbiased lately People never change lol

Who wants to help me find an obscure flaw in G80 and make a thread about it?
