Performance in First-Person 3D Shooters

Call of Duty: World at War

The entry-level CrossFireX tandem has an excellent start, boasting fantastic scalability of 90-95%. That’s close to the theoretical maximum! It cannot compete with the premier-league solutions but easily beats the Radeon HD 4850 and GeForce 9800 GTX+. Unfortunately, its bottom speed is not high enough for playing the game at 1920x1200.

The Radeon HD 4670 CrossFireX is only inferior to the Radeon HD 4870 1GB and GeForce GTX 260 Core 216 in this test, and the gap from the latter is a mere 10% at the first two resolutions and about 15% at 1920x1200. That’s an impressive result for a tandem of two cards each of which costs far below $100. On the other hand, the frame rate is still too low for comfortable play.

We disabled the integrated frame rate limiter in the game console for the sake of comparing the cards. The game’s built-in benchmarking options do not provide information about the bottom speed, so there is no such info in the diagrams.

The tested CrossFireX platform performs well in this game, too. The scalability of the system relative to the single Radeon HD 4670 is 66% at 1280x1024, which is somewhat worse than in the two previous tests.
