Nvidia Reintroduces SLI with GeForce 6800 Series 432
An anonymous reader writes "It's 1998 all over again gamers. A major release from ID software, and an expensive hotrod video card all in one year. However, rather than Quake and the Voodoo2 SLI, it's Doom3 and Nvidia SLI.
Hardware Analysis has the scoop, 'Exact performance figures are not yet available, but Nvidia's SLI concept has already been shown behind closed doors by one of the companies working with Nvidia on the SLI implementation. On early driver revisions which only offered non-optimized dynamic load-balancing algorithms their SLI configuration performed 77% faster than a single graphics card. However Nvidia has told us that prospective performance numbers should show a performance increase closer to 90% over that of a single graphics card. There are a few things that need to be taken into account however when you're considering buying an SLI configuration. First off you'll need a workstation motherboard featuring two PCI-E-x16 slots which will also use the more expensive Intel Xeon processors. Secondly you'll need two identical, same brand and type, PCI-E GeForce 6800 graphics cards.'"

I guess if you have a lot of money and want to play with a (marginal) advantage, an SLI setup is for you.
As for myself, I am a poor college student not even able to afford 1 of these cards. A situation I think is similar to a lot of other geeks/gamers.
Which begs the question, who is this aimed at?

Think of it as an inexpensive way to nearly double your video card's performance at a fairly cheap price when others are upgrading to the new version of the card that is only 40-50% faster (unlike the SLI mode which is rumored to be 75-90% faster).
The tricky part will be that you have to have a motherboard to support it, which for now will only be the ones made for high-end workstations.

>Are you suggesting that the average consumer go out and purchase a 6000q to play HalfLife2?
No? I'm suggesting that connecting two cards via SLI is not very likely to become commonplace, because in the future we'll have multicore or multi-GPU consumer cards instead. They'll perform "twice as fast" but won't use twice the power and twice the space and they won't cost twice the cost.
The reasons for this belief, given current implementation of SLI[0], are many:
1. It req. two slots / lots of space.
6. Multi-core is "the in thing".2. The cards are so expensive, buying two at the same time/price is not very tempting.
3. The development is going so fast that buying a matching card at a later date is going to be a performance and feature loss compared with buying a new single card.
4. Buying a matching card later is only really an option if the drivers for your old one is still being updated (this is somewhat better nowadays than back at V2 time). If not, your stuck with a fast config that only runs well on older hardware and older games. ("Please downgrade to DirectX9!")
5. Do you think nVidia and ATI would like you to buy a new card, or pick up an older one to run in SLI?([0])
7. The new busses are so fast that putting multi-core or multi-GPUs on one card isn't going to starve them.
>fact that your comparing apples and oranges.
Comparing?! I'm not comparing. I'm contrasting two solutions. High-end use both interconnected and multi-GPU tech. I'm simply pointing out that I find it much more likely for consumer hardware to go multi-core instead of SLI.
[0] Must have matching cards, can't mix one generation with the next. If this changed, SLI might have a future.

Something that I'm really interested in knowing is how it compares to Alienware's Video Array [alienware.com] technology. Video array suffers from the problem of being totally useless, because it only increases fillrate but it doesn't improve shader performance. Almost no game these days is fillrate-limited, but many games are limited by shader performances. I hope that NVIDIA's SLI solution is more interesting.
Obviously, the other big thing here is just to have another one-up over ATI. :)

Their target market is apparently "you" - you're just in the wrong place in your cycle.

Soon you'll be in the lust phase, then you'll be in the "MUST BUY SHINEY THING! PLEASE TAKE CREDIT CARD!" phase.
I remember a time when it was unimaginable who might need a 386.
Cooling Requirements? (Score:5, Interesting)
Alienware took a very different tack with their solution [pcper.com] because it requires a 3rd PCI slot AND it's analog (3rd & 4th pics). I guess its a series of tradeoffs: Space vs flexibility, with Nvidia winning the battle for space but losing on flexibility.
That aside, its rediculous that nvidia is expecting their OEM cooling solutions to do any kind of justice to the heat from those cards. Alienware already expects water cooling to be part of the solution and has cases designed accordingly... couldn't NVIDIA have done it any other way? Do they absolutely have to have a hardware link between their cards?
"A power draw of 250 Watts for the 6800 Ultra SLI solution is very realistic."
Then explain how this will work [tomshardware.com].
Makes sense - they bought 3DFX's technology (Score:4, Interesting)
I bought a shitload of 3DFX stock back in the late 90s because they were the king of 3D. I remember walking into a computer store, and seeing something on the screen... I thought it was clip from a movie, but they told me it was Mechwarrior 2 (I think 2) playing on a Voodoo card. My mind was blown. How they got movie-like graphics onto a computer was beyond my capacity to understand. I dropped the $350 and bought one immediately and played with it and loved it.
Then, after a while, I thought, 3DFX is the king and they will never die. I put my money where my mouth was and forked over my entire savings to buy 3DFX, around $15k. There-in I learned a few great lessons:
1) The best technology doesn't mean the best company. "Good enough" with a better run company will usually blow you away. Ask Microsoft or nVidia (well, at the time nVidia wasn't the top runner that it is today).
2) No matter how great of an explanation you make, the stupidest things like 16-bit color vs 32-bit color can kill you (22-bit color just doesn't cut it to the dumb-ass consumers). It's better to just cross your t's and dot your i's in the first place so that you don't have any such vulnerabilities.
They went tits up, and I basically lost my money. nVidia bought the remaining pieces of 3DFX, and that includes all their patents. I'm not surprised they went SLI, and for companies that use it like 3d effect companies, it will probably save them bundles of time.

Fairly often I will get shot by someone I can't see behind the smoke billowing out the top of a broken tank because the person shooting at me doesn't have that bit of eye candy switched on (they still see smoke, but it's easier to see through).
I play with the eye candy turned up as far as I can without getting crappy frame rate because it gives a more immersive experience, not for a tactical advantage.
