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 ...

    Any ideas how the Non Ultra version will perform?

    I cant agree with #45 more. People rush to judgement when its no secret that ATI will be coming out with thier goods very soon also. "Wow look this card is really fast!!! I cant believe it!" well this sounds like almost every other graphics card release from ATI or nVidia in the past. To me nVidia had better have come out with something good after ther lackluster Geforce FX 5800 wasnt anything terribly special. I used to like nVidia alot (heh my ti4600 still runs fine) but when it comes to looking for a new card, I'll pick whichever one is faster *and* has the features I want. If it wasnt for such turnoffs like the 2-slot design and now even 2 power connections required Im not sure I am ready to spend $500 just yet...

    Sorry if im obtuse but if ATI comes out with a part thats either equal (note the key term there) in performance or maybe even slightly slower... I'd go for ATI and thier better IQ that the Radeon 9700 series so impressed me on and made me wish for more out of my ti4600. That and a single slot/single power type design would probably put me in thier boat.

    Fanboy ATI opinion? I've owned nVidia from the Riva TNT to the ti4600 and many in-between.

    #42, the jump from the Ti4600 to the 9700Pro wasn't good for you? I woul dhave thought finally playable AA/AF was quite a jump.
    Personally, it seems less of a jump than the 4600 -> 9700.


    And I will reserve judgement on how much of an accomplishment nVidia have made until I see what ATi release.
    If it's of similar power, but maybe has 1 molex, or is a single slot solution, they will have accomplished more.
    It's not just raw performance, we'll have to see how it all stacks up, and how long it takes to release the things!

    Some site tested the 6800U on a 350W supply and it worked just fine.


    Myself, I think my Enermax 350W with its enhanced 12V rail will take it just fine as well.

    Yeah, Nvidia did make one hell of an accomplishment. They just earned a lot of respect back from both fan clubs. You have to respect the development and research that went into this card and the end result turns out to be just as we anticipated if not more.

    I really don't know how anybody could pick a "club" when seeing hardware like this perform so well.

    Im hoping to see the same results from ATI.

    Just too bad they are some costly pieces of hardware ;)

    nice to FINALLY see a universally quantifiable performance increase from one generation to the next.

    but the important thing is how it competes with the x800 from ati, not against older cards.

    as for the power supply, i think the hardcore crowd that these are geared at already have more then enough power, and quite frankly i would be suprised if these woudln't work fine on a solid 350W from a reputable source (i.e. not your 350W ps for $10 from some 'special' sale).

    They're being conservative knowing that many of the people have crappy power supplies and don't know better.

    "Anyone know when it ships to retail stores?"

    http://www.eetimes.com/semi/news/showArticle.jhtml...

    "GeForce 6800 Ultra and GeForce 6800 models, are currently shipping to add-in-card partners, OEMs, system builders and game developers. Retail graphics boards based on the GeForce 6800 models are scheduled for release in the next 45 days."
  • Jeff7181 - Wednesday, April 14, 2004 - link

    This has me a bit curious... maybe I didn't read close enough... but is this the 6800 or the 6800 Ultra?
  • saechaka - Wednesday, April 14, 2004 - link

    wow impressive. i really want one. wonder if it will run ok with my 380w powersupply
  • Cygni - Wednesday, April 14, 2004 - link

    Personally, im very impressed, and i havent had an Nvidia product in my main gaming rig since my Geforce256. The card may be huge, power hungry, hot, and loud (maybe), but that is some SERIOUS performance.

    How long has it been since Nvidia has had a top end card that DOUBLED the performance of the last top end card? Pretty awesome, I think. I dont have the money to pick one up, but hopefully the mid/low end gets some love from both ATI and Nvidia as well. The 9200/9600/5200/5600 dont really appeal to me... not enough of a performance leap over a $20 8500!
