Hello everyone,

I have long since used Crossfire with my ATI 3870x2, which is a great previous gen GPU where two separate GPU's "must" be in crossfire as a master/slave in order to function. Disabling one is impossible from what I understand, so any games that were poorly optimized for Crossfire often suffered miserably.

THE POINT: So is the 295x2 treated as two separate GPU's by games/OS or is it genuinely one card and not at all a crossfire type setup? It seems to me that the answer could be no but also a mixed of yes and no as well since there are two chips but it's confusing since they share the same die. Are they still considered Crossfire or will any game handle the 295x2 as it would any other single GPU?

For instance, how does the dual chip design really work out in the end for compatibility with all games? I am always told that Crossfire suffers some performance loss no matter what when both cards are being taxed, and from experience I definitely agree. At the same time though that's talking about two separate cards that are linked... what about two cards on the same die though?
(P.S.: I already know stuff regarding the power of the 295x2. For example, I know that 2 290X's in crossfire still do not compare to one 295x2. This discussion is based more on compatibility than anything else)

Thanks!

It's regarded as a single gpu, like the gtx 690 is like a dual gpu rolled into one but it is only a single gpu still, you cn even crossfire 2 r295 x2's

so does that mean that the 295x2 has none of the compatibility issues of a real crossfire setup? So that means that the 295x2 is "both" more powerful than 2x 4GB 290X's in crossfire AND it will also be spared any crossfire issues too since it's considered not to be two separate GPU's (not crossfire)?
