Enemy Territory: Quake Wars
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.
Although this game makes use of very-high-resolution textures, the Gainward HD 4850 1024GB GS has no advantage over the ordinary Radeon HD 4850 if their frequencies are the same. On the other hand, the factory and additional overclocking improve the card’s average frame rate noticeably. When overclocked additionally, the card is almost as fast as the more expensive and hotter Radeon HD 4870 1GB.
Far Cry 2
Far Cry 2 is more sensitive to the GPU frequency than to the amount of graphics memory. The latter parameter doesn’t affect the card’s performance more than 10-11% even at 1920x1200 whereas the increase of the GPU frequency from 625MHz to 700MHz gives the Gainward card a 38% and 54% advantage in average and bottom speed, respectively.
Further overclocking is not so rewarding but has a practical value at 1680x1050: it increases the bottom speed from 22 to 25fps, ensuring more comfortable conditions for play.
