i was wondering about something like this. we have dual core cpu so why not dual gpu. is it even possible? image the speed of those things? do you think we will see dual core gpu in the future?
 
gpu's are multithreaded, that is why they get faster the more pipes you add, essentially its like adding more cores to a cpu.

ati's r700 is rumoured to be multi physical core, lots of little cores adding up for one big punch, that way low end and mid range models can be made easier by just putting less cores on the pcb.

When the 7950 GX most people argue about it, because has two boards and two GPU, but now there is ONE BOARD and TWO GPU!!
Galaxy Masterpiece series support TWO GPU on ONE BOARD :eek:

I'll love to see a G80 dual core ;)
The only bad thing does not support SLI, but if you have one slot and want double performance, even better than SLI, you could try it.
One board gives lower latency so there is a performance increase.
 
Being unique doesn't necessarily mean good, either.

The Masterpiece is an interesting engineering exercise but that's pretty much it: it doesn't actually work properly in SLI (unlike the 7950GX2) unless used with the NForce 4 chipset, and yields exactly the same performance as other dual-GPU solutions based on the same core. So what gives? E-todger size?

As previously said, GPUs are highly parallel; the elegant solution is to add more pipelines for nicely scaling performance; the brute-force solution for graphics bods on a budget is to bolt two together, a la QX6700 (fine, that's two Core 2 Duos, but you get the idea).

It's a nice idea in principle, but only works for a very limited time until the next chip comes out.
 
There have been dual core GPU's being produced every so often, but they never really do well.

There has been the 3D1 from Gigabyte which utilized two GeForce 6600GT cores & also the ASUS GeForce 7800GT Dual (see link).

The problem for these cards has usually been that they are more expensive to make & that means that their price is usually more expensive than the single core cards they were trying to take on in the market place. Eg. the 3D1 which was 2x 6600GT cards was more expensive than a 6800GT which offered the same performance in a simpler package.

The other major problem was that these cards usually only run on certain specific motherboards. Eg the Asus 7800GT Dual can only run on the following motherboards ...
Asus P5ND2-SLI DELUXE
Asus P5ND2-SLI
Asus A8N-SLI PREMIUM
Asus A8N-SLI DELUXE
Asus A8N-SLI
Gigabyte GA-K8NXP-SLI
DFI Lanparty UT SLI-DR
