graphics card. The result is a complete frame rendered at up to twice the performance of a single graphics card.

8How 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.

9Which 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.

10Is a driver profile required to make CrossFire™ work?

No. CrossFire™ is enabled by default for all full-screen 3D games and applications.

11What 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.

12What happens if the CrossFire™ Edition graphics card and the CrossFire™ Ready graphics card have different clock speeds?

Both cards will continue to operate at their individual clock speeds; neither card is “stepped down.” The compositing engine on the CrossFire™ Edition card merges the resulting images independent of the clock speed on either graphics card.

13On what basis are different rendering modes chosen?

When Catalyst™ A.I. is enabled in Catalyst™ Control Center, it determines the optimal rendering mode to use, based on the application or game being used. The default rendering mode is dependant on both the hardware configuration and the application being run.

14What type of performance improvement is expected?

Performance enhancements experienced on a CrossFire™ system depend on the application or game being used. Performance improvements can be increased up to 100%.
