Performance in First-Person 3D Shooters

Battlefield 2142

This game doesn’t support display resolutions of 16:10 format, so we use resolutions of 4:3 format instead.

The Radeon HD 4870 X2 finds this test to be just too easy. Even with the Sideport interface disabled, it has a higher bottom speed than the ordinary Radeon HD 4870 CrossFire configuration. This must be due to the PCI Express switch that allows the GPUs to communicate directly, bypassing the root PCI Express controller and avoiding the associated data transfer latencies.

BioShock

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

Although the game runs on the relatively undemanding Unreal Engine 3 and does not use full-screen antialiasing, the Radeon HD 4870 X2 delivers superb performance, notching over 100fps at 2560x1600 and outpacing the GeForce GTX 280 by almost 75%. As opposed to the classic pair of CrossFire-linked Radeon HD 4870 cards the new Radeon is absolutely stable and has no CrossFire-related problems.
