Once SLI becomes widely used, do you think that 2 6600GTs in a SLI would beat 1 6800 GT? The would be roughly the same price according to New Egg ($420). SLI is gonna make things interesting :)

Yes, there would also be a better % increase with the two 6600GT's. So more bang for the buck if they are the same price.

Do programs have to be written to exploit performance of SLI?
Would you get double FPS or around 30%?

I've read so many different rumors about SLI, someone recently posted here that they have tested to get up to an 85% performance increase with SLI. I guess we won't know till it comes out.

Depends on the game you're playing (at least according to Nvidia's numbers....<font color=red>trust at your own risk!</font color=red>)

No they don't. The drivers deal with the SLI, the game just sees one Graphics card, I beleive.

I believe we should see performace increased in the order of 60% - 80%. Anyless, and I won't be looking into that as an option for my next rig.

I thaught that each card processes its own lines on the screen, or somthing of that nature.

yes Ned it is BUT i dont think many people KNOW this NVIDIA brought out VOODOO when VOODOO was bringing out the 5500 Voodoo.

nvidia has spent 2 years on a sli setup using Voodoo technology INTERESTING YES.

Basically voodoo just carried on in nvidia both technologys integrated.

Consider this the VOODOO 5000 was the FIRST EVER on board proccesser grafix card not the geforce 256, but before these cards could be released they where took over by nvidia secretly.

there was a gfx at the time more pwerful than the geforce 256 and that was the voodoo 6500 (with SLI ability) about a dozen where ever made, in SLI it was 2.5 times more pwerful than the 256 geforce. it never made it to production because of nvidia.

Nvidia got all rights to Voodoo technology, in turn nvidia took lead role as no1 GFX comapny of that time e,t,c e,t,c.

there should be websites dedicated with this stuff if u wanna read more just search for it.

i read this in a computer magazine (PCformat) in the uk like a couple of years ago.

voodoo 5000 had 2 proceser
5500 4
6000 4 SLIoption plus more ram
6500 6 SLI etc

There are alot of Voodoo sites, and they have been mentioned here often.

A good site with alot of pics of prototypes and actual working cards;

yeah 1/2 1/2 splitting. And then each card keeps to its own 1/2 and never crosses the border unless forced to do by some driver.

Theres a video here

Though thtas of the ALX video array, but Nvidia SLI will be doing the same thing on the screen.

those look so rusty. Not many fancy fans/heatsinks too. Soon we'll see out cards like that. :smile:

Actually based on the pics at [H] it looks like there will be 'dynamic load balancing' and that they will be able to cross the median depending on workload.

It'll be interesting to see that in action because it's going to have to do extra work simply to determine what side of the screen to split on, but probably in the long run it'll end up being a net benifit, as long as the game is not CPU limited and this chews CPU cycles. More investigation when it's out should quickly determine that.

aah, never knew that. How do they decide the border line ? Extra CPU cycles will be spent with those.
Well in that pic we see the lower portion is smaller maybe bcos it has more moving parts, like water flowing (is it ? that pic is too small, or is it just rocks that require more rendering), grass moving etc. And if this actually dynamic, then there might be something for mismatch OCed cards ?

There isn't much of a decription of exactly how it will do this.

I heard <A HREF="http://www.geocities.com/verminboy_99/Evil.wav" target="_new">one explanation</A>, but I doubt it. :lol: 

If it has to calculate something like mpixel/textels per region and work from that it's likely to have a significant impact on performance, which may greatly explain the range of improvements from application to application.

I would think this will be far more complex than just the run-time compiler. If they do alot of work on the front end then we can expect driver/games updates to be easier, but a far more complex system to make it work, which may explain all the time it took to develop. It's going to be interesting to see ALX versus SLI because they do you different methods, but it does appear they have similar method (not truely interleaved except for in the loosest translation),also it'll be interesting to see how ALX works with 4 cards. And whether it's 2 or 4 cards, how does it determine which is top, middle, bottom, etc.

So if you mated cards with different speeds, could you adjust the size on the region the card controls as to make the cards comparable?
