CrossFireX tested on Gigabyte GA-MA790GP-DS4H AMD 790GX+SB750 mainboard with 2 Radeon HD 4850 graphics card
Bluetooth 7 Aug 2008

CrossFire X

As the board comes with 2 PCIe slots and support CrossFire X, we tested the board with the Phenom 9550 with 2 pieces of ATi Radeon HD 4850 graphics card. The driver used is the same beta driver we used for the IGP tests. Here is a breakdown of the results:

	Radeon HD 4850	Radeon HD 4850 in CrossFire	Difference (%)
3DMark05	14234	14583	+2.4%
3DMark06	10578	11359	+7%
3DMark Vantage	P6207	P8387	+35%
DOOM3	111.9 fps	106fps	-5%
FEAR	89 fps	114fps	+28%
Lost Planet	Snow 49 Cave 58	Snow 91 Cave 57	Snow +85% Cave -1.57%
Call of Juarez	33.6 fps	33.5 fps	-0.29%

The CrossFire performance only gave a slight boost in 3D performance. This is largely due to the CPU bound applications. The performance would be better if a better CPU is used to tap the power of the 2 graphics cards.
