Performance in First-Person 3D Shooters

Aliens vs. Predator

This game is benchmarked in DirectX 11 mode with the highest graphics quality settings.

The Matrix 5870 doesn’t do as a single-processor Radeon HD 5970 even at a GPU frequency of 1 GHz and doesn’t allow playing comfortably at 1920x1080 but our overclocking helps improve the bottom speed to 25 fps at 1600x900. That’s good considering how AMD solutions perform in this test in general. The 2560x1600 results indicate that 2 gigabytes of onboard graphics memory are redundant for graphics cards like Radeon HD 5870.

Battlefield: Bad Company 2

Our overclocking is the most rewarding at 1600x900 where the Matrix 5870 is close behind the Radeon HD 5970 while consuming the same amount of power. We have a smaller effect from overclocking at the higher resolutions, especially at 2560x1600 where the three versions of Radeon HD 5870 produce almost identical results. The Matrix 5870 doesn’t benefit from its 2 gigabytes of onboard memory, but we can see that its RV870 processor overclocked to 1 GHz can successfully compete with such solutions as the Nvidia GeForce GTX 480.

Call of Duty: Modern Warfare 2

Overclocking the RV870 chip is not rewarding here. This game runs just as well on the ASUS Matrix 5870 as on any standard Radeon HD 5870. Performance can only be improved greatly by switching to dual-processor solutions such as the Radeon HD 5970.

Crysis Warhead

This is the first time we can see a positive effect from 2 gigabytes of onboard graphics memory: the ASUS Matrix 5870 beats the reference card from AMD at 2560x1600 and has a higher bottom speed than the Radeon HD 5970. Alas, its frame rate is still lower than playable. The results we can see at the lower resolutions suggest that RV870-based products can match senior models based on the Nvidia GF100 chip. They only need a GPU clock rate of about 1 GHz for that.
