Crossfire & SLi

post #1 of 16
Thread Starter 
Hi all,

Can anyone tell me if there is any difference at all between Crossfire and SLi and if there is, which is better/prefered?

Cheers

Crossfire is using 2 Ati cards, SLI is using 2 nVidia cards. There isn't really any "better" because it depends more on budget.

Crossfire is ATI
SLI is Nvidia

You need a crossfire board to go crossfire.
Same goes for SLI.

Better/preferred...its all (to me) whatever fits my budget best. You've got an SLI motherboard....so you're obviously going to be better off with SLI.

Crossfire = 2 ATI cards
SLI = 2 nVidia cards

Certain motherboards only support either SLI or Crossfire, or neither. (Or in some instances, both, like the newer X58 chipset for socket 1366 CPU's). It (partially) depends on the chipset and PCIe slots available on the motherboard.

EDIT: Only certain ATI or nVidia cards support Crossfire or SLI, as well.

Ah, yes.

Tri-SLI = Three Nvidia cards
Quad-SLI = Two nVidia dual-GPU cards
Crossfire-X = Three (or more) ATI cards, or a dual-GPU card + single GPU card
"QuadFire" = Two ATI dual-GPU cards
