Performance in Strategies

Company of Heroes: Opposing Fronts

The new add-on to Company of Heroes is tested in DirectX 10 mode only since it provides the highest quality of the visuals.

CrossFire technology shows its effect at a resolution of 1600x1200 where it amounts to 18%. The performance gain is 25% at 1920x1200 but the bottom speed doesn’t grow up much. It is only at 2560x1600 that the Radeon HD 4870 CrossFire shows the efficiency we may expect from it, about 85%. Alas, the bottom speed is low. It is also low with the GeForce GTX 280 that has 80 texture processors and 1 gigabyte of graphics memory. The GeForces are faster than the Radeons at the lower resolutions, though.

Once again we can see that the Radeon HD 4870 X2 is better for playing at high resolutions than the pair of ordinary Radeon HD 4870 with 512MB of graphics memory.

Command & Conquer 3: Kane’s Wrath

The add-on to C&C 3: Tiberium Wars brought no changes into the technical aspect of the game. The game still having a frame rate limiter, you should consider the minimum speed of the cards in the first place.

The CrossFire platforms both reach the frame rate limit at 2560x1600 and provide a somewhat higher bottom speed in comparison with Nvidia’s solutions. This makes no practical difference, of course.

World in Conflict

The Radeon HD 4870 CrossFire is again ahead of the Radeon HD 4870 X2 at every resolution, save for 2560x1600.
