Crysis

This game is tested at the High level of detail, excepting the Shaders option which is set at Very High. This way we try to achieve a compromise between image quality and speed.

Alas, there is no breakthrough which we had expected. The Sideport interface will hardly make it possible it, too. Anyway, the Radeon HD 4870 X2 delivers good performance and outpaces the GeForce GTX 280 in this test. The gap is especially large at 2560x1600 where the Radeon HD 4870 X2 enjoys a 45% lead in terms of average speed. ATI’s solution also features superb stability which is not observed with the classic CrossFire tandem.

Enemy Territory: Quake Wars

The frame rate is fixed at 30fps in this game as this is the rate at which the physical model is being updated at the server. Thus, this 30fps speed is the required minimum for playing the game.

The Radeon HD 4870 X2 is roughly equal to the Radeon HD 4870 CrossFire configuration at ordinary display resolutions but goes ahead at 2560x1600, leaving all its opponents far behind. The reason is obvious: the game features MegaTexture technology that operates with 32768x32768 textures (they are as heavy as 3 gigabytes in uncompressed form), so 1 gigabyte of local graphics memory comes in handy here.
