What is the difference between a CrossFire™ Edition graphics
card and a standard graphics card from the same family?
CrossFire™ Edition graphics cards include a "compositing engine", a
chip that takes the partially rendered image from the Slave graphics
card and merges it with the partially rendered image from the Master
graphics card. The result is a complete frame rendered at up to twice
the performance of a single graphics card.
8
How are the graphics cards connected on a CrossFire™ system?
The two cards are connected by an external cable. The cable is
attached from the Slave graphics card's DVI-I connection to the
CrossFire™ Edition's CrossFire™ connection, which is used to
convey information from the Slave graphics card to the Master
graphics card and transmit the combined signal to a display device.
9
Which games/applications work with CrossFire™?
CrossFire™ works with all full-screen 3D games and applications.
Catalyst™ A.I. is enabled by default in the Catalyst™ Control Center
software. This automatically selects the optimal rendering mode for
the application.
10
Is a driver profile required to make CrossFire™ work?
No. CrossFire™ is enabled by default for all full-screen 3D games
and applications.
11
What happens if you pair a two CrossFire™ Edition graphics
cards with different architectures?
In this scenario both graphics cards will operate at the speed of the
slower graphics cards while in CrossFire™ mode. You will be
required to restart your computer for this matching to take place.
