With the Lightsmark test running at 1920 x 1080, the Radeon HD 4770 continued to compete with the GeForce 9800GT. The Radeon HD 4770 was faster than the Radeon HD 4850 by a greater margin, but still behind the Radeon HD 4870.
When running Lightsmark at 2560 x 1600 the same trends can be gathered. From fastest to slowest the order was the Radeon HD 4870, Radeon HD 4770 (830/800MHz), GeForce 9800GT, Radeon HD 4770 (750/800MHz), Radeon HD 4850, Radeon HD 4830, and then the Radeon HD 4670 in last.
