quick crossfire question

post #1 of 4
Thread Starter 
Do you have to use the crossfire adapter to be able to crossfire? my friend seems to think you dont have to since sli you dont have to. I showed him how my system wont go into crossfire without the adapter and he still dosnt beleive me, so, do you or dont you?

they have special chip sets where you don't - but for the most part, yes you do need the adapter

SLI and Crossfire bridge adapters are sold for good reasons

There are a few instances where you dont need connectors,what cards are you trying to crossfire?

There's software crossfire/SLI which does not require the bridge/adapter. However, that's mostly for lower end card whcih the bandwidth between the PCIe/Chipset is suffcicent to transfer the data.

On higher end cards, a small section of the GPU is dedicated to crossfire/SLI and dependent on the bridge. Without the bridge you will have additional CPU overhead which will generally lower performance as the CPU/Chipset will have to compute the instructions that would otherwise be handled by the integrated master chip in each GPU that communicates over the crossfire/sli bridge.
