Benchmarks: World in Conflict
When testing with World in Conflict we found the new Radeon HD 4850 was able to match the performance of the original GeForce 9800 GTX with AA/AF disabled. The upcoming GeForce 9800 GTX+ on the other hand was 4fps faster at 1920x1200, placing it just in front of the dual-GPU powered Radeon HD 3870 X2.
Enabling AA/AF in World in Conflict was what the Radeon HD 4850 needed to get back into the lead, producing 33fps at 1920x1200 or 7fps faster than the GeForce 9800 GTX+. This also made the Radeon HD 4850 faster than the Radeon HD 3870 X2 graphics card, which was impressive.
