Performance in Third-Person 3D Shooters

Lost Planet: Extreme Condition

It is only on Nvidia’s SLI solutions, including the GeForce 9800 GX2, that this game used to run fast enough at the maximum settings, but now the Radeon HD 4850 comes into play, conquering the resolution of 1280x1024 and outperforming the GeForce 9800 GTX by 40%. You won’t have to lower the level of detail on the new graphics cards if you play at that resolution.

Why is the RV770 so fast in this test? The new core contains a lot of architectural optimizations but seems to benefit the most from the 40 texture processors. It is clear that the memory bandwidth doesn’t limit the speed because the Radeon HD 4870 is only 15% ahead of the junior card at 1920x1200. When the display resolution is so high, the memory bandwidth usually becomes an important factor irrespective of the game engine.

Tomb Raider: Legend

The ATI Radeon HD 4850 loses to the GeForce 9800 GTX in this test although ensures a comfortable speed in every display mode. It is competitive against the GeForce 8800 GT 512MB, so that’s not a total defeat. The more advanced Radeon HD 4870 is behind the GeForce 9800 GTX at first but overtakes the opponent at 1920x1200 thanks to higher memory bandwidth.
