Probably a bit of old news for a lot of you but <A HREF="http://www.theinquirer.net/?article=10601" target="_new">The Inquirer</A> finally realized this and made an article about it. To summarize, here are main parts:

- There will be some kind of bridge to make it work with current AGP boards.
- Built using 0.13 micron and IBM will play with this chip to make it work for nVidia.
- Most likely won't have 8x2 pipelines, 16 pipelines is impossible at this time; so its speculated that it'll have 12 pipelines.
- Impracticle to use more than 256-bit memory interface, expected to use DDR II as its still too early for GDDR2.

Any thoughts?

This is probably right since NV40 is more like and evolution of the FX family(just like the GF4 was for the GF3 and the GF2 for the GF1). SO it all make sense, starting to move towards PCi-X to match the future chipset. No GDDR yet and no smaller Process like 90nm should also be right...The NV40 should still be a beast, take a 5900 tweak it some, crank the frequency maybe add pixel/vertex shader 3.0 and you should get 50%-100% performance gain over the current FX family.
 
speculation


just like the 5800ultra was supposed to be 100% faster than anything else on the market at its release? ill believe it when i see it

Totaly agree, anyting b4 the release is speculation. Like the DDr2 at 1ghz in the 5800, everyone was like whoa. Now the 5900 use DDR...But nvidia showed a demo with NV40 with 3 dawn rendered at the same time. That why i think the speculation is close.ALmost the same technology just faster...
 
PCI Express is coming this soon? within the timeframe of the next generation of video cards.

I thought it was still a couple of years off.

2004 is the year of pci-express, all intel boards for prescott based cpu's.. or so..

i for myself can't wait for it, as it will solve most of todays problems for me.. happy..


not that i believe in the nv40, though.. but in the pci-express.. will be great to finally make real video-cards again, for the screen output, and rendering cards.. for rendering onto some screenbuffer.. and they can get "stackable".. .... dreaming..

but finally, coprocessors could get doable again.. rocks! raytracing all the way! [-peep-] off nvidia rastericers, [-peep-] off ati rastericers.. we want real graphics, not some artistic paintings!

And PCI express supports mutliple high speed cards! Too bad boards will only come with 1 of the "good" slots!

I assume you are talking about high speed 64bit/66Mhz Raid cards and the like?

Actually, I'm refering to high end video cards. The short slots (x1) will probably be fast enough for almost anything except video, and you'll probably only find one of the long slots (x16) on most boards.

I should also note that even the lowely PCI-Express x1 slot is nearly 2.5x as fast as PCI, so it could be an OK slot for low end video cards.

now that's something to think about......... remember dual Voodoo 2s?? Dual FX6000Ultra~~ (drools)

I'd get a nVidia GeForce FX 5900Ultra... if THEY WOULD CHANGE THAT #()#@ HSF
 
well thats nice.
I dont know much about PCI express.
Do the devices share bandwidth, or are they all independent?

If thats the case then 2.5x of PCI should be enough bandwidth for all but the highest levels of SCSI raid.

oh yes... i remember SLI :smile:

One could use 3d glasses at a full 120Hz or so.
yummo.

LOL, sure if you can find a board with 2 x16 slots! Good luck! Do we REALLY want to put such an advanced card in a 1x slot, that's not even as fast as AGP2x?

Sorry, I answered that the wrong way! YES I want 2 top notch video cards, with 4 displays (3 surround, 1 overhead), to enhance my 3D gaming experience!

I really can't remember, and the articles I've read are so technical it would take me a while to find it (too long for my liking), but IIRC all those x1 slots and the x16 slot will be routed back to an x32 hub independantly.

Actually a PCI-Express x1 slot is about the same speed as...Ultra320 SCSI, so a single "crappy" slot should still be good enough for most cards, except video cards.

So what do you want? dual video cards?
hmmm...

Yep, and I even said it back in <A HREF="http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=355008#355008" target="_new">THIS</A> post when we first talked about this kinda stuff.


MMMMmm can't wait. Triple video cards. One center (R420?) and 2 'surround' (rv380?) now that's how it's supposed to be done! 😎

Can't wait, can't wait!

nope, about real realism.. photos aren't animated, ya know😀


i really do hope they split graphic cards and 3daccelerators again.. so you can have cards with good quality screen connectors, or tv-outs, or what ever you require, and, independend from it, 3d accelerators, as much as you want for it.

and hopefully there will be a SaarCOR release for pci-express.. at best combinable😀 several of them..

Photo-realism - def. appears as realistic as a photograph. Does not appear generated, renderered, etc. Lifelike.

<b>56K, slow and steady does not win the race on internet!</b>
 
I must admit that idea appeals.
3 or 4 large LCD's with low ms response times all running 1600x1200 with full AA and ansio.

i know. but there's more than just a photo that mathers. we have to simulate time as well, namely effects like motionblur and similar time-based effects. rendering photo-realistic _is_ doable today. problem is, a lot of effects don't behave mathematically correct at 100%, so while one photo looks good, once you move, you can determine irregularities..

and yes, once you added realistic reaction on moved scenes, it looks much more natural.

and i know what you mean with photorealism. but you agree in the end you don't want to watch photos.. you want to watch movies.. well.. you want to play them actually😀

both will be doable..

thats about what we want realtime.. photorealism? definitely..

sorry to be blunt everyone... but woopty-f****ng-doo, photo realism.

Is it just me, or does everyone just wanna play interactive real-time rendered moveies?

remember when they first managed to fill up CD's with FMV's we had the interactive movie "game"... methinks we'll get something similiar when they finally put out real time radiosity lit scenes etc... :)

<b>I'll say here and now: games are nothing without gameplay</b>, sorry to appear the cranky spoil-sport, but really... the games you're gonna remember is the one that was a good game, not necessarily the one with photo realistic graphics.
