  • Hardware Utterly disappointed Nvidia 2080 video compression performance!

    For 38.8GB to 25GB compression:
    1) It takes Nvidia 2080 16 minutes, $800.
    2) For half of the price of 2080 at $400, Nvidia 1070 takes 17 minutes.
    3) More surprisingly, takes the $500 AMD Vega 64 19 minutes, perhaps DVDFab is not optimized for AMD GPU architecture. Vega 64 beats 1070 easily at 2K and 4K gaming.

    Hi,
    From our dev guy.
    Nvidia Play game use different part compare to video encode. After Pascal they use NVENC chips for video encode.
    For example, gtx1050 1 nvenc chip, GeForce GTX 1070 - 1080 2 nvenc chips, GeForce GTX Titan X 3 nvenc chips,
    In DVDFab current use only one nvenc chips, ( fulldisc need get size of converted files do decide not converted video bitrate)
    So use one NVENC chip gtx1050 vs gtx1080 in video encode, there may be about 10% speed up.
    Nvidia 2080 Turing mostly up for game and play video, not much for NVENC chips.

    So your can ran multi DVDFab.
    Or in future DVDFab add better support for parallel task .

    When concern about video Encode, order should be Nvidia > Intel > AMD .
    Only AMD not support HEVC main10 encode for now.
    But for game and other things AMD is much better than Intel, maybe sometime Nvidia.

    They mostly update for better game render first.


    yours,
    Wilson

      Thank you, Wilson and your dev guy, Fengtao, I feel like I know him from Modern War. :-)

      I returned the 2080, not worth the upgrade and money.

      It would be great if most of the programs like DVDFab can detect the underlying hardware and utilize it to the max.

        That timing above is for transcode from an external drive via USB3.0 interface. When copy the file to M.2 nvme drive and transcode from nvme drive, it shortens to 6.5 minutes for Nvidia GTX 1070. I don't have the Nvidia RTX 2080 card to test, returned, but it probably drops to 6 minutes for Nvidia RTX 2080 and 7 to 8 minutes for Vega 64.

          This is the reason that I'm doing my transcode on a GTX 1050 (~$120 at the time). It has the same NVENC chip as the better models, just less of them, but it doesn't matter.

          In regards to the RTX series of cards. NVIDIA claims that they're capable of doing the same quality of H.265 with a smaller file size. I'm not sure how to interpret that, but to me it seems to imply that it has a newer NVENC chip. I'm not interested in smaller file sizes, so perhaps that may mean better quality given the same file size?

          If there is a quality difference, not sure how significant it would be... but I'm toying with the idea of picking up a "cheap" RTX 2050 when they eventually come out to get my hands on the new version of the NVENC chip.

          Now if Fab dev guy actually ends up updating Fab to support parallel encoding... it may be worth picking up a 1070/2070 to get the 2 chips. Will be keeping my eye on the release notes for that feature!

            Unless you play the 5 or 6 video games that uses RTX , the 2080Ti is a total fail.
            Intel i7 5960X Extreme
            Asus X99 Sabertooth
            32 gbs of Corsair Dual Channel Memory@2133mhz
            Samsung 1TB 850 Pro, Samsung F3 1TB
            Swiftech H20-320 Edge Kit Cooler
            Windows 10 64 bit Pro
