Performance in First-Person 3D Shooters
Call of Duty 4: World at War
The frequencies being equal, the Gainward card is no better than the reference sample equipped with 512MB of memory even at 1920x1200. The factory frequencies improve its performance somewhat while the additional overclocking helps close the gap from the Radeon HD 4870 1GB at low resolutions. When the resolution is high, the latter’s ultra-fast GDDR5 memory says its word. The overclocked Gainward HD 4850 1024MB GS is ahead of the GeForce 9800 GTX+, mainly in terms of bottom speed.
The game appreciates large amounts of graphics memory: the Gainward card is somewhat better than ATI’s reference sample even at 1280x1024, the gap growing up quite large at 1920x1200. The factory overclocking doesn’t affect the card’s performance much while the additional overclocking (when not only the GPU, but also the memory chips are clocked faster) makes the Gainward card as fast as the Radeon HD 4870 1GB. Alas, every card has a rather low frame rate in this game. None of them can provide a bottom speed higher than 25fps even at the lowest resolution.
