Dual AGP slots?

Will there ever be MOBO's with 2 AGP slots? I know you can get cards with 2 display outputs, but would there be any advantage (in performance) by having 2 agp slots with 2 cards running in SLI anymore?
 
It can't currently be done. HTi shas been discussed before. THe thing to remeber is that agp is a port not a slot. So it isn't like simply adding another slot. The entire chipset would need to be redesigned to support it. IT may happen one day but at the moment it is unlikely.
 


<< I thought the whole idea behind AGP was putting the graphics card on its own, dedicated bus. >>



That is correct. Therefore in order to have two slots you would need two busses which as i mentioned above would involve redesigning the chipset you want this on...
 
Yeah hanpan's got the right idea.

You have add a second AGP controller to your chipset.
That's a whole bunch more traces on the motherboard, and a whole bunch more transistors in the north bridge. You can't add AGP in parallel like you can PCI slots.
 
well assuming the whole chipset was redesigned to have two separate busses for 2 separate cards, where the second card would need to be identical to the first card so they could be connected together, what kind of performance gains might there be?

100%, 200%, 5%? Would it be similar to the performance gains of setting up v2's in SLI?
 
<AGP doesn't support dual cards...>

Matrox g450 dualhead AGP??? doesn't support dual cards? :Q

it does on my machine...😎
 


<< Matrox g450 dualhead AGP??? doesn't support dual cards? >>

A Matrox G450 isn't dual cards. It's dual monitors driven from a single card. Big difference.
 
you CAN use an AGP + PCI video card at the same time to get dual monitors. I've tried this on win98 and it works. dunno about win2k. why don't you consider getting the GeForce cards with the TwinView option? basically, dual monitor outputs on one card.
 


<< why don't you consider getting the GeForce cards with the TwinView option? >>



I'm not buying anything, I'm just asking about systems with 2 AGP ports.

I know you can run 2 PCI video cards (voodoo2) in SLI and you get increased performance.

Now imagine if you could have 2 AGP GF3's running in SLI. 2x as much processing power, 2x as much memory (and 2x as much memory bandwidth?).



<< stefan..........i like the way you think!!...bigger better faster >>



I think thats how everyone here thinks 😀
 
Even if such a mobo did exist with 2 AGPs. No card made now can support SLI in AGP although it may be possible to make a card that does
