Benchmarks: Left 4 Dead, Resident Evil 5

The Radeon HD 5770 continued to perform well in Left 4 Dead, almost matching the performance of the GeForce GTX 260. Although it was slightly slower than Nvidia's competing card at each resolution, it was also a bit faster than the Radeon HD 4870. At 1920x1200, the new 5770 was 25% faster than the Radeon HD 4770.

Resident Evil 5 performance trends were similar to those of Left 4 Dead, which could have something to do with the zombies, though we are not sure.

At 2560x1600, for example, the Radeon HD 5770 was just 1fps slower than the Radeon HD 4870 and 2fps slower than the GeForce GTX 260. This made the 5770 an impressive 38% faster than the old Radeon HD 4770.
