Performance in Simulators

Race Driver: GRID

The Radeon HD 4770 is not much faster than the Radeon HD 4830 and GeForce 9800 GT at first, but breaks away from its opponents at 1680x1050 and begins to compete with the GeForce GTS 250 512MB. It is quite successful in the competition: the gap is only 5% then and shrinks to zero at 1920x1200.

Like in many other tests, the new card is as fast as the Radeon HD 4850 at the overclocked frequencies and even beats the latter at 1920x1200 notwithstanding the 128-bit memory bus.

We use the in-game benchmarking tools that do not allow to measure the bottom frame rate. We also enable DirectX 10.1 support for ATI’s solutions.

This is a highly resource-consuming game, and there is no talking about comfortable performance when it comes to $100 graphics cards. Anyway, we can note that the Radeon HD 4770 is close to the Radeon HD 4850 and leaves no chance to the Radeon HD 4830. Also, that’s not enough to compete with Nvidia’s solutions at 1280x1024, which is the only playable resolution here. The Radeon HD 4770 is competitive to the GeForce 9800 GT and even GeForce GTS 250 512MB at the higher resolutions, but is 36% and 44% slower than them at 1280x1024.
