Far Cry 2

Radeon HD 4770 and Radeon HD 4850 graphics cards compete successfully in Far Cry 2 game in the “light” quality mode. As soon as we enable graphics quality enhancements, HD 4850 takes the lead in this race, even though its fps rate is still low. The additional 512 MB of video memory on Radeon HD 4890 start to pay off, which you can clearly see from the results comparison against HD 4870. And the dual-processor Radeon HD 4870 X2 is probably the only graphics card in our today’s test session that can provide comfortable framerate in any resolution and with any image quality settings.

Left 4 Dead

Not very resource-hungry game according to today’s standards, Left 4 Dead, allows even the owners of inexpensive Radeon HD 4730 to play comfortably and the power of Radeon HD 4870 X2 is absolutely unnecessary here. The performance differences between the cards are quite comparable with their price differences.

Lost Planet: Colonies

Lost Planet: Colonies is another game where Radeon HD 4770 can compete successfully against Radeon HD 4850. I also have to point out very sad results demonstrated by Radeon HD 46xx and excellent work of a CrossFireX configuration represented by Radeon HD 4870 X2.
