I don't fully understand how crossfire works. I do know that it involves using two gpus to increase graphics performance. However asymmetrical crossfire uses two different gpus. My question is there a way where you could turn one gpu off? For instance I was looking at a laptop that uses an amd 8650G+8670M w/1gb of memory.
I read that this combo is actually inferior than a single amd 8670M. However, some sites stated on some games, the performance was better than an Nvidia 740m gt. Overall I was curious if I could turn off the 8650G when gaming and use the 8670m while gaming instead of both.
One last thing, I have not yet purchased this system. Im still trying to research this before buying anything.

I believe AMD has a program you can download that will let you disable one of the GPUs, but I haven't bought anything AMD in years so I'm not sure. but nVidia can do it so I don't see why AMD couldn't. It seems like a pretty basic feature to not have. --- "The easiest way to stop piracy is ... by giving those people a service that's better than what they're receiving from the pirates." ~ Gabe Newell.

If it's anything like regular crossfire on a desktop, you can disable crossfire in the CCC.
