Performance in Third-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 ATI Radeon HD 4850 lays claim to leadership in its class right from the start. It is somewhat slower than the Nvidia GeForce 9800 GTX, but the difference in average frame rate is a mere 6% at 1920x1200, for example, while the minimum speed is the same. It means both cards provide the same level of playing comfort while the ATI Radeon HD 4850 is far easier to use because it is smaller and doesn’t need two power connectors.
The game is not new and doesn’t utilize the powerful computing capacities of the new core. This is the reason why the ATI Radeon HD 3870 X2 is faster, but this interesting dual-processor solution from ATI is living its last days. As you can see, the Radeon HD 4870 is about as fast as the dual-processor card while having only one GPU. The idea of installing two GPUs on one PCB is still alive, though. Being one of the cornerstones of ATI’s new strategy, it will be embodied in the ATI Radeon HD 4870 X2 which is going to become a real champ among single graphics cards.
BioShock doesn’t support FSAA when running in Windows Vista’s DirectX 10 environment. We benchmark graphics cards without FSAA in this game.
The Radeon HD 4850 is somewhat slower than the GeForce 9800 GTX at 1280x1024. At the higher resolutions the new card is just as fast as Nvidia’s monster. Not knowing exactly the reason, we suppose it is due to the new memory subsystem, particularly the caches, as well as to the improved architecture of the rasterization units.
The Radeon HD 4870 beats the GeForce 9800 GTX easily, setting a new record – over 100fps at 1600x1200. Obviously, the Nvidia GeForce 9800 GTX+ with increased frequencies won’t make a good rival to it whereas the Nvidia GeForce GTX 260 is considerably more expensive.
