Performance in Simulators
Race Driver: GRID
The Radeon HD 4890 is faster than the GeForce GTX 285 at the lowest and highest resolutions but the gap is only 2% at 1680x1050 and 1920x1200. The performance growth relative to the Radeon HD 4870 1GB is 14 to 21% depending on the resolution. And the new card has no rivals when overclocked, beating both the GeForce GTX 285 and Radeon HD 4850 X2.

We use the game’s built-in benchmarking options which cannot measure the bottom frame rate. We enable DirectX 10.1 support for ATI’s solutions.
For an unknown reason the Radeon HD 4890 is just a little better than the Radeon HD 4870 1GB in this test. The gap is smaller than 4% at resolutions up to 1920x1200 and grows to 9% at 2560x1600. Overclocking adds 12-18% more, yet the GeForce GTX 285 and Radeon HD 4850 X2 are still superior at the lower resolutions. At high resolutions the frame rate is too low for smooth gameplay.
