Performance in Third-Person 3D Shooters

Battlefield 2142

This game doesn’t support display resolutions of 16:10 format, so we use a resolution of 1920x1440 pixels (4:3 format) instead of 1920x1200 for it.

The Radeon HD 4870 CrossFire and GeForce GTX 280 both handle this test easily. They ensure high speeds even at a resolution of 2048x1536 pixels. The Radeon tandem is somewhat faster in the hardest display mode but the difference is less than 5%.

Talking about the usability factor, the Radeon HD 4850 CrossFire subsystem requires an appropriate mainboard but the cards are shorter than a GeForce GTX 280, occupy two slots like the latter card, and need two 6-pin power connectors whereas Nvidia’s card won’t work without your attaching an 8-pin PCI Express 2.0 connector to it. Nvidia’s card is more economical, though. Its peak power consumption is 178 watts as opposed to 200 watts of two Radeon HD 4850 cards working in CrossFire mode.

BioShock

BioShock doesn’t support FSAA when running in Windows Vista’s DirectX 10 environment. We benchmark graphics cards without FSAA in this game

Alas, the Radeon HD 4850 CrossFire configuration doesn’t show stable results in this test. Its performance doesn’t go near the predicted level. Moreover, CrossFire mode is downright incorrect at 1920x1200 where the average frame rate of the tandem is lower than the speed of the single Radeon HD 4850.

The 2560x1600 results are disappointing for the CrossFire system due to the low bottom speed. Nvidia’s solution, on the other hand, delivers comfortable performance in terms of both average and minimum speed. The single Radeon HD 4870 is also good here and seems to be the most valuable investment for this game.
