nVidia Introduces Dual GPU Systems

nVidia has decided to give new life to an old Voodoo concept and has announced nVidia SLI which will allow multiple GeForce 6 Series or Quadro graphics cards to operate in a single PC or workstation for increased graphics horsepower. Appearing later this year in PCI Express-based PCs and workstations from the world's top manufacturers, the new nVidia SLI technology will take full advantage of the additional bandwidth and features of this new high-bandwidth bus architecture.

Interestingly enough Alienware, who will also be launching its own Video Array dual GPU system in Q4 2004 (ALX), is also listed as a partner. nVidia seems to be creating a product which will allow other system builders to compete with Alienware, this competition however will leave Alienware with one advantage over its rivals, that its own setup will, most probably, support ATI cards as well. It will be interesting to see how this battle of the ultimate PC will progress, especially since it may well develop into a battle between system builders.

nVidia SLI is a patent-pending hardware and software solution that enables system builders to connect two PCI Express-based GeForce 6 Series or Quadro graphics boards on their PCI Express-compatible motherboards. The technology features an intelligent communication protocol embedded in the GPU and a high-speed digital interface on the graphics board to facilitate data flow. A complete suite of software provides dynamic load balancing, and advanced rendering and compositing to ensure smooth frame rates and outstanding image quality.

Unreal Engine 3 has an insatiable appetite for fill rate and polygon throughput, running shader programs of 50-100 instructions per pixel to achieve advanced per-pixel lighting and material shading. nVidia's SLI technology running on PCI Express motherboards provides an incredible performance increase of up to 2x, bringing next-generation gaming up to even higher resolutions and frame rates, stated Tim Sweeney, founder and president, EPIC Games.

Systems based on SLI multi-GPU technology are expected to become available in the second half of 2004 from the world's leading PC and workstation manufacturers including:

-Alienware - North America, Europe
-Atelco Computer - Germany
-Boxx Technologies - North America
-Falcon Northwest - North America
-Mouse Computer Japan (MCJ Co., LTD) - Japan
-Network Technical - Sweden
-Paradigit - Holland
-Scan Computers - UK
-TSUKUMO Co., Ltd. - Japan
-UNITCOM INC - Japan
-Velocity Micro - North America
-ThirdWave Corporation - Japan
-VoodooPC - North America

Almost all cards will not overclock to 20% or greater for both memory clock and core clock. That's performance increase. The fact that you can over-clock the 475mhz X800pro to 506mhz out of the box on standard cooling and even push it to 525mhz and mod the pipes to 16 from 12 is quite intriging. That alone gives you a huge performance increase over the X800PRO without doing that."While testing the Power Color card, I saw a significant differences from the 472MHz clocked Power Color card and the same card with Overdrive turned on was working on 492MHz and even 506MHz.You have to have a cool case to get to 506MHz or you can simply add some additional fans close to the card to help it out, as we explained yesterday.At 44 degrees Celsius, the GPU starts rocking at 506MHz but we had to place one fan on top of the card, a standard Akasa 8cm fan that glows blue and rotates at less then 2000 RMPs to do the job.I tested with 506/890 MHz and we gained only 200 more points in 3dm03 but proved that cards are stable at this speed and can possibly go even faster.When I tried to overclock I could easily reach 525/1000 MHz frequencies and get 10500 3dmarks from the default 9613 - a quite significant performance jump.Top of the pops was the 525/1120 MHz retail shipping speed of X800PRO Platinums with the exception that our card had only 12 pipelines enabled while the normal platinum has 16."-TheInquirer.net-This is why i am going to grab a X800pro when i find the cash.

With a stock heatsink on a gpu the average oce is 13%, with my l337 methods involving attaching heavy heatsinks and high cmf fans 20% oces are not that hard. So long as the voltage is ample.Now i want to have a bitch about ATi's overdrive.It's heat related, the hotter the gpu gets the less it overdrives. So when your gpu has something that actually strains it and it gets hot the clock goes back to stock levals. But when something is a push over it gives you frames you dont need. Which increases the average fram rate but gives no in game performance. It shows in nvidias cards haveing a higher minimum fram rate. grrrr

"It's heat related, the hotter the gpu gets the less it overdrives..."City you realize what you are saying? If the GPU gets hot and the clock speeds do not reset back to their levels, the Chip can almost certainately overheat and melt. It's called a fail-safe. And of course it's heat related! Would you want the overdrive feature to over-clock irregardless of the heat dissapation of the gpu? How would you know if the levels were reaching critical? And even if you had a GPU heat sensor monitor, it could be too late. How many stories have you heard about people over-clocking their GPU's too much and destroying it? Many. You DO NOT want to have the over-drive feature to increase over-drive if the heat is at it's zenith on the chip. That's insane. Unless of course you have Uber cash to watse for a new $499 card.This feature is great. Stop nit picking and come up with something better. And if heat is a concearn with the overdrive as you claim. Then buy a passive cooler and 1 more fan to allivaite this issue. I have done this with my 9800XT. Overdrive works great for a 0.15 chip. And i can see the X800PRO using this feature as seen tested greatly. 500+ overclock is nothing to laugh about. 1150mhz memory is great also. Have you seen the results from it? Totally stable with good cooling. Not water cooling like Nvidia needs for the 6800Ultra from GainWard.....stop nit picking Cit, and find a real issue with ATI cards....

nVidia Introduces Dual GPU Systems

I have to agree with sam. You don't want the overdrive feature to keep clock speeds up if the heat continues to pose a danger. That in itself would be commercail disaster for ATI. You know how many people would be bitching that thier card melted? Remember the fiasco with the 5800 cards and the stopping of the gpu fan when a 3d screen saver went on? Talk about heat issues and melting. That card was hot to begin with. The overdrive safty is a good one. You can only overclock your card so much before it craps out and you get problems. Kudos for ATI to have this. Coyuld save you a few hundred bucks otherwise.

nVidia Introduces Dual GPU Systems

Arrrrg!, your all missing the point!!!ok, in a game, it comes to a real graphic part, the gpu goes under full load, hence the gpu gets hot, hence the overclock goes down, so when you actually need the extra performance you get none.When your in a less graphic part, less gpu load, more overclock when you already have decent frames.In effect overdrive is just increasing the peak performance, not the lower levals. And thats the bitch i'm having. But since you brought it up overdrive does shorten the life span of your chip.

nVidia Introduces Dual GPU Systems

All over-clocking irregardless shortens the life span of the GPU.[url removed] that's not good increases as tested, i don't know what is. I have no idea where you are getting your facts City. Do you have a X800 or 9800XT and using the overdirve feature? How fast is your CPU? If your CPU is too slow, then over-clocking is useless as the CPU is the bottleNeck. You know that. Right? Do you even have the tools to back up your claims and tests? From the early review of the X800PRO from Power Color, what you are saying here is totally the opposite."When overclocked, this card will give you a huge performance increase, it's up to you to find the suitable speeds and set it but 1200 3dmarks more won't hurt anyone."And i am sticking to what i said. When the intense "graphic" parts come in the game, ALL GPU'S no matter who makes them gets hot. That's becasue at that time the GPU is doing more calculations to render those scenes. A.K.A the 5800 and it's blowing fan on 3d scenes.The over-clock overdrive feature is there to push the card to it's limit without frying your card.If i am to understand what you are saying, then soon as the ATI gpu gets hot, overdriver lowers? Correct? The numbers alone from the Inquirer proves your theory wrong. Bring me some facts to varify your staements. Just don't say it.

Listen Nvidiots bitches!!1. X800pro outperforms the 68002. X800XT outperforms the 6800GT3. X800XT Platinium outperforms 6800 ultra4. R480 will outperform all5. R500 will be a behemoth.Winner ATI for three years running now!! All review sites say that the R420 series outperforms the NV40 series, so don't deny it!!

*Chucks a spastic*ok, your showing me benchies of a card which had extra cooling to keep it's bitch of a core below 44 degrees. So that overdrive would stay on. All the scores shown were AVERAGE frames, the minimum frames were not shown. Minimum frames is all that matters! Who cares if a card can go to a max of 2000^20 frames a seccond if it has slow downs reducing it to 1fps. If you check the benchmarks which include minimum frames the nvidia cards are more than often higher, but the maximum frames have the ati cards bouncing ahead. Giving ATi the higher average fram score even though a game may play smoother on the nvidia rival."Yes. The new ATI OVERDRIVE™ control panel lets users safely maximize the performance level of their graphics processor. ATI OVERDRIVE™ intelligently determines the optimal speed of the graphics processor by constantly monitoring the temperature of the graphics processor, ensuring that it always stays at a safe level." From the ati website.In the nice hot australian climate chips stay hot. hence when the graphic load becomes alot in a game overdrive is basicly gone. so when the frames start stuttering because of a pretty part in a game were we NEED the speed boost we get jack.Doing a manual overclock is different as it stays at the oce through the heavy and not so heavy loads. Sure it's more dangerous but extra performance is always there when needed. The also did that with the overdrive on the benchmarks you showed me.Am i the only one who sees this?

To the person directly below me:We dont f*cking compare cards on their names, we go by price.

"If you check the benchmarks which include minimum frames the nvidia cards are more than often higher, but the maximum frames have the ati cards bouncing ahead. Giving ATi the higher average fram score even though a game may play smoother on the nvidia rival."Show us those numbers that show Nvidia numbers are higher on the minimum in most cases. Good luck. It's a 50/50 split right now with the R420 and the NV40 as seen by most sites. I can show you sites that show ATI minimum frame rates are higher. And then i can show you other sites that show Nvidia minimum frame rates are higher. Check OCP.COM...Check Tom's Hardware.com...Check TechReport.com..Check them all. The numbers flip bacl and forth."In the nice hot australian climate chips stay hot. hence when the graphic load becomes alot in a game overdrive is basicly gone."Are you serious??? I live in Houston Texas and the temps in the summer reach 100+ easy for weeks on end. I HAVE ZERO PROBLEMS WITH MY OVER-DRIVE as i have good cooling. My over-drive works perfectly. My chip stays cool. What is your point?????? Are you that foolish to use standard cooling or limited fans if you live in hot climates when over clocking your card? Any card. Not just from ATI???? You don't have AC in your home? Please City. You are too much. You are reaching. Your Nvidia fanboyism is shining through.Which brings me to this point...If you plan to over-clock your card no matter if it's manual over-clocking or ATI's over-drive system, you should have approiate fans to keep it cool. Otherwise your're a moron."Doing a manual overclock is different as it stays at the oce through the heavy and not so heavy loads..."You know you can by-pass the overdrive system and use a 3rd party over-clocking software application?

"Also note that the x800 cards are much more available. Meaning that the 6800's prices will go down when they become more available.YAY, tripple post"Please explain why that would happen? If X800's are more available, why would the cost of the 6800 go down when it was just released????? It's only when a GPU has been on the market for some time does the price drop. Especially when that company plans to release it's successor. If anything, the price would reflect the market. The cost of it's direct competitor. The X800. And do you also know that it cost less to produce R420's then the NV40's, as R420's have less transistors? So your comment on that is....silly. You need to take a simple business course.Just because the 6800 will become more available in the near future(which it should!) does not make it cheaper. Case in point. The 5950. It still cost more then the 9800XT."The 6800gt costs: $770 AusThe x800pro costs: $704 AusThey are neck to neck."How do you figure? The X800pro is cheaper and both cards are almost neck and neck. The frame rate differences are not visible noticable on both accounts. The X800pro can overclock to 500+ and 1150 memory clock speeds. Also it can be modded as seen by many to a full 16 pipelines. When this was done, the X800pro surpassed the same priced 6800gt card in almost every respect."The 6800U costs: $924 AusThe X800XT costs: $913 AusX800 takes the lead with filtering on."The X800XT wins flat out because if you do not use filtering(FSAA+AA) on a $499+ card, you are retarded. Also. The XT800 is a 1 slot card solution that can fit in any PC tower. The 6800Ultra cannot. Try fitting a 6800Ultra in a Form Factor tower.Currently the competitor to the XT800platinum edition card is the 6800Ultra from GainWard. It's a beast of a card and the fastest chipset out period. But it also costs $799US and uses a waterblock cooler to get those 5% frame increases over the XT800 across the board. Please tell me, is that w

ps3.0 HAS MAJOR POTENTIAL the same way PS1.4 did over PS1.0 and PS1.4. The issue here is Game Developer participation. Shader 3.0 is more effiect then shader model 2.0. However, Game Developers have to implement it for it to be a reality. At this point, only 1 title supports it out of how many games out right now? And even with Crytek spending 6 months of optimizing it for the 6800, the results bring it on par with ATI cards now.

nVidia Introduces Dual GPU Systems

There are no visial differences between ps 2.0 and 3.0 now. In the future there will be. Think it has something to do with the amount of effects in a scene or something, meh.Ok, if i heard anyone say you cant buy the 6800 range, um grr, here are a couple of places you can buy it which it know of.[url removed] They are f*cking available. (yes they are IN STOCK in these websites)You seem to know your hardware, and should know that the clockrate of antyhing has little to do with it's performance. There are many more factors. Sure it's true that a larger die makes it harder to ramp the clock speeds, nvidia made that sacrifice for ps3.0 support. The difference should be made up when more 3.0 titles our out. Seing that i upgrade every 3 or so years the nvidia offering is probably the best for me.It's true their goal is to compete with ati, but thats just from nvidias perspective. Many of the companies produce both ati and nvidia based cards. In this case competition between manufacturers comes in. Currently for the 6800's there isnt much competition from other manufacturers. So prices are slightly inflated. You say the cores from nvidia are larger, therefore cost more. True, but that doesnt matter. Nvidia has a large finantial backing and is probably putting in alot of money to keep cores reasonably cheap for their partners so their cards will be compeditively priced and more companies will see selling their cards under their name profitable.Like the 9800se there is only the small chance the pipe trick will work. Other times it immage will be increadibly distorted. Not to mention the dammage you can do to your card attempting a pipe trick. Any card can be oced

"never said overdrive didnt work fine in hot conditions, my bitch is the peak performance increases, but not the minimal frame rate. I'm not explainging why again."I have gone to numerous sites and the minimum fram rates for the 6800 or the x800 change all the time. One sites shows it's faster for the x800, another site claims the 6800 is."In the future there will be. Think it has something to do with the amount of effects in a scene or something, meh."In the future ALL gpu's will support PS3.0 or greater. (2005-2006)This is the point. The advantage Nvidia claims that they have over all ATI cards is PS3.0 when infact it will take almost a full year or two to use PS3.0 fully. A.K.A Unreal 3. That game will be fully PS3.0 capable and released in 2006. And the R420 or the 6800 will run that game poorly. Below exceptable frame rates. Tim Sweeney himself even states this to some degree. He states Unreal 3 is a Next Generation game."There are many more factors...."Totally agree with you. 100% And here's the twist. Because both GPU companies have produced for the first time, comparable cards in performance, every little increase in that performance becomes a factor. Both chips have the same pipelines. Both chips have the same amount of vertex shaders. Both chips use similar AA and FSAA techniques. The 2 major differences are PS3.0 and Clock speeds. PS3.0 as seen offers good speed bumps for PS3.0 enabled software/hardware. But does nothing for the others. Look what the Patch does for the 5950...oucch! Increased clock speeds for memory and core clock give you greater ability to run games at higher resolutions with AA and FSSA on at better frames rates. (The reason people spend $499 on high-end cards) Why? Because the higher the clock speeds, the greater the fill-rate and greater the band-width. This is why in general most games that are band-width hungry and benefit from Higher Fil-rates(Hve to have a good CPU) ATI cards run them faster.So you have t

I have seen what buying for the future did for Nvidia's FX LINE. And City, when you get that 6800, Call me over so i can see you try and play Unreal 3 at 800x600 with fsaa on. ;) GOOD-LUCK.

Yes i am a nvidia fan boy, my tnt2 did that. Just like your a ATi " ".Just saying that kills your credibility City. In a big way. Were you a "FANBOY" of Nvidia when they released the FX line? The whole FX line was a failure from the start to finish. Poor shader performance. Piss poor PS2.0 perfromance. And ohhhh, the PR spin and lies from Nvidia. I, unlike you City work hard for my money. And have no alligence with any corporation that is out to take your money. If they want my cash, they need to work for it. Nvidia and the FX line for the past 2-3 years did not do that. At all. I had a geforce3 and geforce4 card. When the R300 came out i tried it at a freinds and i was sold. Then i waited to see Nvidia's response. The NV30, NV35, NV38. All failures. And the lies that continued to fester from them made it worse. The r420 at this time stacks up pretty damn good to the NV40 in every respect. Until ATI screws up, i will stick with them. No favorites for me. I don't have the money to be that stupid to buy products that are sub-par just to be loyal.....

"Like the 9800se there is only the small chance the pipe trick will work'Do what everyone with a half a brain did. Wait until you know which brand card mods correctly. I did this with my 9500. And worked perfectly. I suggest everyone do the same if they plan to get a X800PRO.And the Farcry quote you pulled from Tomshardware. Very impressive. Too bad that's the only title out that uses PS3.0 at this time. And if you're lucky, you just might see 1 or 2 more before 2005. If those titles are not delayed. Then comes the R500, and the NV50. Too late for the NV40 to take advantage....Another point you are forgetting also. Not everyone will be buying a 6800Ultra or a X800. They will stick with the 9800's or 9700's or 5950's or 5900's. And this brings up this point. Nvidia is moving away from supporting those gpu's as seen by the latest driver releases that did sweet f all for performance on the FX chips. It's sad actually. Now City, you know that Nvidia relies heavily on optimizations for shader 2.0 with the whole FX line as Nvidia did not follow MS specs on D3D ps2.0 support. Moreover, the FX chips have 1 less vertex shader then ATI's R300 chips. Because of this, their shader performance in those PS2.0 games are slower. They have to lower persion and cut other corners to get those frame rates up. How do you think the fx line will handle games in 2005-2006 that will be all PS2.0 and PS3.0 and no hybrid PS1.1 and PS1.4 operation when they seem to be dwindling complier shader support in it's drivers? I feel sorry for 5900 owners if they plan to keep their FX cards for another year or so. If you look at titles that use PS2.0 now, Nvidia's complier program in their drivers reduce the shader operations to PS1.4 when applicable. They will not be able to do this with titles like HL2 and others that are PS2.0 fully compliant. And you talk of future proofing? The fx line was said to be more future proof then the R300. We all know the truth now about this.

nVidia Introduces Dual GPU Systems

The places you mentioned in your links are online buying. The vast majority of people do not buy their cards online. Just look at retail numbers. At this time, you cannot buy a 6800 in any store. You can though buy a X800pro in FutureShop, BestBuy and EB if they are not sold out......
