Cross Generation Multifire

post #1 of 3
Thread Starter 
Hey guys

Not in the know about the whole multi-fire thing but i was wanting to know

a) can you put two cards from different generations in crossfire?

b) Is it in any way stable? does it increase performance?

Thanks!

For the most part no, but there are exceptions. Not every game will see improvements, but most will. It depends on the drivers and the game. It's pretty rare to see negative scaling, so you'll almost never lose performance. Most games see an increase but not all.

As for stability, if it's on that chart it'll work. Crossfire and SLI in general have their issues, one of the main ones being stuttering. But radeon pro is supposed to be a big help with that.

No.


There are situations with rebranded cards with different generational names however since they are rebrands it is still the same generation. For ex. 6770 = 5770, etc etc. Thus the rule remains no for different generations.
