Performance in First-Person 3D Shooters
Call of Duty: World at War
The Sapphire HD 4850 X2 hits first. The card is 4-6% ahead of its opponent in every resolution save for 1680x1050 where the gap is as large as 16%. To be more specific, the two RV770 cores, even clocked at 625MHz and limited by the relatively slow memory, can maintain a higher bottom speed than the single G200 core. This advantage has practical value at the resolution of 2560x1600 where the Leadtek WinFast GTX 280 cannot deliver a comfortable frame rate.
The new Crysis is somewhat less heavy than its predecessor, yet the speeds are very low at the maximum level of detail, making you forget about playing at high resolutions. The opponents are equals in this test. Although the advantages of CrossFireX technology can be seen at the resolutions higher than 1280x1024, this cannot be viewed as a victory because the game is virtually unplayable at a frame rate of 11-20fps.
