Service Fudzilla tested the new Radeon HD 4890 from XFX. It was a matter of checking on the performance gain for DirectX version 10.1. Tests conducted on a Tom Clancy game, HAWX at a resolution of 1920×1200 and 2560×1600 px.

Look at the results. The Full HD resolution of the game was about 8 or 9 more frames in DirectX 10.1, and 2560×1600 resolution was about 6 and 7 frames for more than DirectX 10.
