AMD Dual GPU cards.How do they work?

Hyedwtditpm · Mar 16, 2014

Does anyone know how these new Dual Gpu cards work? Do they work just like CF but on the same card?

What would be the min Psu ? any guess?

You didn't give a link or even name the card so nobody can help you much.

However:
1) YES. Dual-GPU cards are almost identical to Crossfire (AMD) or SLI (NVidia).

2) The rule-of-thumb for POWER SUPPLIES is to get one with sufficient PCIe 6/8-pin connectors.

Other:
There are often a few reasons such as PRICE, or VRAM, Noise etc that make a dual-GPU card a poor choice.

AMD's Crossfire is still not as good as NVidia's SLI. For example, DX9 issues have yet to be sorted so games like Half Life 2 that are DX9 can run at a perceived 30FPS even though 60FPS is reported. Ironically the game runs better when turning OFF the second GPU/card.

I'm looking to buy a new monitor (1440p), and afaik only way to get a 60fps average is to either these dualgpu cards or CF. So i guess dual gpu is more pratical than CF , right?

A 290X or 780Ti should do quite well at QHD, though it might have trouble if you use Ultra settings in some games.

is there a new gpu in the roadmap for Nvidia and AMD? 1440p is becoming very common.

Not for a while yet, by memory. Dual Hawaii card (Two R9 290s or 290Xs) is rumoured, though.
