NVIDIA Enables PureVideo on GeForce 6 GPUs

Our next set of tests are taken entirely from The Best of Friends Volume 3 DVD. As we mentioned earlier, Friends is recorded at 24 fps but is flagged as 30 fps source, which provides a good stress test for DVD decoder detection algorithms as well as de-interlacing abilities. Our first scene shows a similar number of artifacts on both the ATI and NVIDIA GPUs, image quality appears to be identical across both GPUs.

The next test is similar to what we saw in the Big Lebowski test, with ATI incorrectly using data from the next field to weave with the previous field resulting in a poor quality image. NVIDIA doesn't suffer from the same problem which is a win for PureVideo.

If we look at the blinds in the corner as well as the jaggies on Chandler's shirt we see that NVIDIA comes away with another win.

    Oh, nevermind, that's for PCI Express 6800s, which are apparently the only cards that use the NV41 core. AGP 6800s use the NV40 core.

    For anyone who wants it the link on Nvidia's site seems to working I just downloaded it.

    How does the 6800 have acceleration support if it's also based on the NV40 core?

    "At the same time, ATI sent us information on how to enable hardware acceleration of WMV9 on their cards before the forthcoming WMP10 update."


    would someone care to share this with the rest of us ?

    I hope nVidia plans to add support for decoding MPEG4-AVC HP at some point. Whether it's this product line or next, MPEG4 will be important for next generation optical media (whether it's HD-DVD or Blu-Ray).

    What makes me truly upset is that so far, the sites reviewing PureVideo has not take a stand for the consumers that own the 6800 and were promised the full PureVideo featureset by nVidia. Rather, sites are reviewing the tech, and ducking the issue, as if they are more concerned about continuing to receive nVidia products for review than they are for us. Who's looking out for the little guy?

    P.S. Anandtech's review states that the 6800 Standard has a fully functional video processor --this isn't fully true, as the AGP version according to nVidia's website, does not.

    Great review. Even though Nvidia doesn't always win the deinterlace test, it wins on picture quality in most tests.Looks like a 6600 Nvidia will be replacing my ATI as the next video card in my htpc.

    That is so retarded that it doesn't fully work on the 6800GT/Ultra. Why would they cripple their high end cards? I guess since they aren't very available it doesn't really matter. Hope they add the rest of the functionality to new revs of these cards.

  • GnomeCop - Monday, December 20, 2004 - link

    wow I guess they will get away with touting this feature on the AGP 6800Ultra/GTs , even though it doesn't fully work after all.

  • jg123 - Monday, December 20, 2004 - link

    I don't see a link on Nvidia's website for a trial mentioned in this article.
