SLI? Crossife? Why not dual core?

With AMD and Intel both heavily investing in dual and probably quad core technology.

How come ATI and nVidia are promoting the cross fire and sli options?

Surely it would make sense for them to staty selling dual core GPU's?

For a start it would free up a lot of space, rather than have two gpu's, just one would be needed.

With dual core GPU's surely there would reduced latency then with seperate cards.

Perhaps this might be the case, considering AMD have bought ATI.

mmmm, two dual core X1900XT's.

Now thats power!!
 
3d cards are comparitively new compared to CPU's.

We saw multi CPU rigs a lot earlier than multi core. It's a lot easier for them to make some sort of bridge and some software than to design the chip from the ground up with dual core in mind.

Plus it gives the benefits of adding on a second card later... I'd like to see you add an extra core.

No doubt in years to come we will see multi core graphics.
 
Also, the vast majority of games will currently run happily on single-core-single-gpu graphics cards, with multiple cards being largely the preserve of those with money to burn.

Until games start to push the requirements of a single core gfx card, and people with dual gfx setups become more common there is no imperuts for the gfx card manufacturers to push forward with the massive investment of designing a whole new core from the ground up.
 
GPU are also somewhat different to normal CPUs due to their functions being different. At the moment a dual core GPU might not provide enough gains to make it worth designing a dual core architecture.

Last year Gigabyte released a Dual GPU (not dual core) board with two 6600gt cores. 3D1 it was called.

SLI, and the idea of linking two gpu's has been around since the voodoo days of 1999.

Im just thinking that with the investment that AMD have made in dual core technology, that some of this can be applied to ATI.

I would have a little bet that we see dual core GPU's next year.

Why? Because its a selling point. Like vista isnt really that much better than xp, but yet everyone wants it.

Likewise the new gillette razers. 6 blade apparently. SIX!! I cant see how different thats going to be than my 2 blade. But hey, some people gotta have em

Uses two boards, two sets of RAM and is essentially two cards using one PCI-E slot.

As Zefan mentioned the GX2 is not an example of this. However, in the late 90s multiple GPU cards were available to high-end customers. They fell out of fashion rather quickly.
