Dual Video Cards Return

Kez writes "I'm sure many Slashdot readers fondly remember the era of 3dfx. SLI'd Voodoo 2's were a force to reckoned with. Sadly, that era ended a long time ago (although somebody has managed to get Doom III to play on a pair of Voodoo 2's.) However, Nvidia have revived SLI with their GeForce 6600 and 6800 cards. SLI works differently this time around, but the basic concept of using two cards to get the rendering work done is the same. Hexus.net has taken a look at how the new SLI works, how to set it up (and how not to,) along with benchmarks using both of the rendering modes available in the new SLI." And reader Oh'Boy writes "VIA on its latest press tour stopped by and visited in the UK and TrustedReviews have some new information on VIA's latest chipsets for AMD Athlon 64, the K8T890 and the K8T890 Pro which supports DualGFX. But what has emerged is that DualGFX after all doesn't support SLI, at least not for the time being, since it seems like nVidia some how has managed to lock out other manufacturers chipsets from working properly with SLI. VIA did on the other hand have two ATI cards up and running, although not in SLI mode."

New trend ?

[FiReaNGeL]

Dual video cards... soon dual-core CPUs, is it a sign that we're slowly approaching the Moores Law limit? The 'dual' strategy allow for further performance gains.... but I can't see myself using more than 2 video cards (hell, I can't even see myself using more than 1), so that will be a very temporary solution.

And we're not even speaking of how much power (wattage) these 'dual solutions' consume...

The 'dual' strategy allow for further performance gains....

Eventually, barring any further technological advances, perhaps we'll even result to modular clustering. Once again, the enthusiast's computer will be larger than a refrigerator! ;-)

I don't think so. Quoting from Intel's web site: "Moore observed an exponential growth in the number of transistors per integrated circuit and predicted that this trend would continue." Many people assume Moores Law states that speed of processors will double every 18 months and that the fact that it is becoming difficult to increase clock speed now means that Moores Law is finished. However, increasing speed is a consequence of higher clock speeds and higher transistor counts. Dual cores means you can increase the number of transistors per IC more and actually use them to do real work rather than simply adding a huge cache (as was done with the latest Itanic). End result, more speed, higher transistor count, and Moores Law still fine. In fact, dual cores could mean that the transistor count increases at greater than Moores Law in the near term. Of course some might question whether a siamesed pair of processors actually constitutes a single IC.....

Looks better on SLI Voodoo2's than on my Rad 9800.

You can already buy from the alienware luxury collection some gaming systems featuring SLI

Double The Money

[Squeebee]

So the guys at Nvidia were sitting around when in walk the PHB and says "Guys, we need to make more money". And flunkie one says "Hey, let's release a new card, all the fanboys will rush out and buy it!" PHB says "Well that's ok, but we do that enough already". Flunkie two says "I know, let's convince the users that the one overkill video card they buy is not enough, let's convince them that the need to buy TWO!" And the rest my friends, is history! Stay tuned for the new quad-card cash-vacuum, coming soon.

Should have invested in...

Dual webservers. Would have delayed the Slashdotting.

Ironic?

I find it funny that some of the people who lamented the $15/mo. for WoW in the last article are probably the same people who will go out and drop $600 for a top-notch SLI video setup.

Buy the second a year later

[PIPBoy3000]

The real benefit, from my perspective is that it's a low-cost way to upgrade your video card in between new computers. I bought my first Voodoo 2 for $300. My second cost $30.

Re:why so little support for gamers?

[meestaplu]

Right now, the answer is pretty simple. If you want a game to use multiple processors at the same time, you need to include more than one execution thread--the programmer has to divide the work in such a way that two or more processors can do it. It's quite hard to build a multithreaded game; there was some SMP support in Quake III, but it wasn't very stable and didn't provide a huge performance boost.

With a multithreaded application, you have to guard against strange bugs that are very, very hard to fix. If your multithreaded application runs into a deadlock every hundred thousand frames or so, it will be next to impossible to isolate, and production will end up being slower than it already is. While I'm sure that writing multithreaded games will happen in the near future, I don't think it will catch on very quickly.

Err you aren't trying hard enough.

You obviously don't have much imagination if you can't think of a use of more than two video cards/monitors.

As a lover of flight sims I'll be first in line to buy a mother board that can support 10 video cards. Along with an array of cheap monitors I will finally have a wrap around view of the sim world. This can apply easily to any game.

First person shooters could finally have peripheral vision (one center and two on the sides) along with a inventory and map screen. Brings the grand total to five.

Driving games could finally have a true perspective instead of the stupid 3rd person or 1/3 screen in car view. So at least three monitors.

RTS resource monitors, sat view, and ground maps. Well that could become quite the array depending on how much you wanted covered. Say anywhere from 3-12 monitors.

Same for Massive Multiplayer Online Games. I could see a use without trying hard that would require at least six monitors.

You could double, tripple or even quadruple up on the number of required cards for any one monitor that would require higher end graphics. There are always those twisted monkeys that come up with graphics that won't run on any one GPU these days. For example those lovely to the horizon maps that show up in various games that add about 100meters of high detail every year. I see another scenario where people boost their systems performance by picking up cheaper versions of cards they own to keep their graphics improving without breaking the bank. (We can all remember when GF 2 cards cost $400 each, that'll buy you 50 of them these days.

Who could afford all this you ask? Well just about anyone these days. I've got a stack of 17inch CRT monitors in the garage I picked up for $5 a piece that are just begging to be used. With the advent of sub $100 video cards and CRT monitors, and the fact that not every output would have to be super hi rez. Perpheral views, 2d maps, and inventory lists would be just fine on something to the equivalent to a GeForce 4 MX ($32 new). You could seriously enhance your gaming machine for the price of one top of the line latest and the greatest video card from ATI/Nvidia.

So you keep your two monitor display, for me I'm going to check to see if the wiring in my computer room can handle the extra 10 monitors I plan on adding.
