Programmable Encoding Anyone?


That's right, NV4x includes a dedicated programmable video processor. The video processor is made up of an address, scalar, vector, and branch unit. The vector unit is a 16 way SIMD (a single instruction can operate on 16 different pieces of data at once) vector unit.

We don't have anything to test this thing with right now, but there is a whole lot this thing can do, including inverse 3:2 pulldown (conversion from interlaced TV format to progressive format better suited to computer monitors), colorspace conversion, gamma correction, MPEG 2 MPEG 4 WMV9 DiVX decoding and encoding, scaling, frame rate conversion, and anything else you'd like it to do for you.

This a very exciting feature to be included on the GPU. It essentially means that anyone with an NV4x chip including the video processor will be able to stream video all over the place, do very fast encoding, and offload a lot of work from the processor when it comes to video processing. Also, it could really help in multimedia and PVR style systems by lowering the necessary CPU power to something more affordable (that is, as long as this functionality is included across the board on NV4x chips).

This could actually really help even the playing field between Intel and AMD if it catches on ...

    Shinei,

    I did not know that. </Johnny Carson>

    Derek,

    I think it'd be very helpful if you listed the game version (you know, what patches have been applied) and map tested, for easier reference. I don't even think you mentioned the driver version used on each card, quite important given the constant updates and fixes.

    Something to think about ahead of the X800 deadline. :)

    I've seen a lot of comments on the cost of these next-gen cards. This shouldn't surprise anyone...it has always been this way. The market for these new parts is small to begin with. The best thing the next gen does for the vast majority of us non-fanbois-who-have-to-have-the-bleeding-edge-part is that it brings *todays* cutting edge parts into the realm of affordability. Reply

    Bah! My almost 2 year old 9700pro is good enough for me now. i think i'll wait for nv50/r500....

    Also, a better investment for me is to get a new monitor since the 17" one i have only supports 1280x1024 and i never turn it that high since the 60hz refresh rate makes me go crazy

    Ahem, this card has been tested by some people with a high-quality 350W power supply and it was just fine.


    Considering that anyone who could afford a 6800U would have a good powersupply (Thermaltake, Antec or Enermax), it really doesn't matter.


    The 6800NU uses only one molex.

    Oh my god...$400 and u cant even put it in 75% of the systems on peoples desks today without buying a new power supply at a cost of nearly another $100 for a quailty PS...i think this just about has to push all the fanatics out there over the limit...no way in hell your going to notice the perform improvement in a multiplayer game over a network..when does this maddness stop.

    Pete, MP2 DOES use DX9 effects, mirrors are disabled unless you have a PS2.0-capable card. I'm not sure why, since AvP1 (a DX7 game) had mirrors, but it does nontheless. I should know, since my Ti4200 (DX8.1 compatible) doesn't render mirrors as reflective even though I checked the box in the options menu to enable them...
    Besides, it does have some nice graphics that can bog a card down at higher resolutions/AA settings. I'd love to see what the game looks like at 2048x1536 with 4xAA and maxed AF with a triple buffer... Or even a more comfortable 1600x1200 with same graphical settings. :D

    I'd like to see benchmarks of Painkiller in the upcoming NV40 vs R420 tests... Reply
