NVIDIA GeForce 6800 Ultra: The Next Step Forward

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 ...

Well I hope this card is on par with ATi's or visa versa. ATi is planning to see their best at $500 pop and Nvidia is selling their at $400. How long to you think ATi is going to see their card for that price if the performance is virtually identical. Finally in the terms of the Power. Makes me wonder why PCI-Ex doesn’t include enough voltage from the socket? VPU's are getting to the point that they are just as powerful and complex as their CPU brethren, and will require the same power requirements as the CPU. Some one didn’t do their homework I guess. Well hears hoping that it will be in the next specification.quikah - Wednesday, April 14, 2004 - link
Can you post some screen shots of Far Cry? The demo at the launch event was pretty striking so I am wondering if PS 3 were actually enabled since you didn't see any difference.Novaoblivion - Wednesday, April 14, 2004 - link
Wow nice looking card I just hope the new ATI doesnt kick its ass lolRudee - Wednesday, April 14, 2004 - link
When you factor in the upgrade price of a power supply and a top of the line CPU, this is going to be one heck of an expensive gaming experience. People will be wise to wait for ATI's newest flagship before they make any purchase decisions.Pete - Wednesday, April 14, 2004 - link
Nice review, Derek. Some impressive performance, but now I'm expecting more from ATi in both performance (due to higher clockspeed) and IQ (I'm curious if ATi improved their AF while nV dropped to around ATi's current level). I also have a sneaking suspicion nV may clock the 6800U higher at launch, but maybe they're just giving themselves room for 6850U and beyond (to scale with faster memory). But a $300 12-pipe 128MB 6800 should prove interesting competition to a ~$300 256MB 9800XT.The editor in me can't refrain from offering two corrections: I'm pretty sure you meant to say Jen Hsun (not "Jensen") and well nigh (not "neigh").

Looks like a fantastic card, however I will wait for the ATI numbers first :)PS:
Thanks for including the 9700 Pro. I own that and it was nice to see the difference.

Derek, could you post the monitor you used (halo at 2048 rez), and any comments on the look of things at that monstrous a resolution?Thanks.

does the size and the power requirement basically rule out using this beast of a card in a SFF machine?Damarr - Wednesday, April 14, 2004 - link
It was nice to see the 9700 Pro included in the benchmarks. Hopefully we'll see the same with the X800 Pro and XT so there can be a side-by-side comparison (should make picking a new card easier for 9700 Pro owners like myself :) ).DerekWilson - Wednesday, April 14, 2004 - link
We are planning on testing the actual power draw, but until then, NVIDIA is the one that said we needed to go with a 480W PS ... even making that suggestion limits their target demographic.Though, it could simply be a limitation of the engineering sample we were all given... We'll just have to wait an see.
