Performance in First-Person 3D Shooters
This game doesn’t support display resolutions of 16:10 format, so we use a resolution of 1920x1440 pixels (4:3 format) instead of 1920x1200 for it.
The new card looks good right from the start, outperforming the Radeon HD 3850 in bottom speed. It is also better in terms of average frame rate at1600x1200. Although the results of the Radeon HD 4670 are everywhere high enough for comfortable play, it cannot compete with the GeForce 9600 GT. The gap varied from 16-18% to 35% depending on the display resolution. ATI’s new memory controller is more efficient than the G94’s controller, so the defeat can be explained by the weaker RBE subsystem. The twofold difference is too big to be made up for by the architectural advantages of ATI’s rasterization processors.
Anyway, the performance of the new Radeon is high for a $79 card and even superb if you compare it with the GeForce 9500 GT. The latter can hardly provide a comfortable speed at 1280x1024 whereas the ATI solution makes the game playable even at 1920x1200.
BioShock doesn’t support FSAA when running in Windows Vista’s DirectX 10 environment. We benchmark graphics cards without FSAA in this game.
If the new Radeon has any problems with rasterization performance, they only show up in the somewhat lower bottom speed than that of the GeForce 9600 GT. Both cards deliver playable speeds at resolutions up to 1600x1200 inclusive. Their speeds fluctuate too much at 1920x1200, bottoming out below 25fps. The Radeon HD 3850, on its part, maintains a frame rate higher than 30fps. This card isn’t yet outdated.
The GeForce 9500 GT is totally routed by the Radeon HD 4670, losing from 46% in the lowest resolution to 55% at 1920x1200.
