Benchmarks: Aliens vs. Predator, Alan Wake
When testing Aliens vs. Predator at 1920x1200, the HD 7770 Crossfire cards delivered an impressive 65fps -- 38% and 33% faster than the GTX 560 Ti and HD 6870. The HD 7770 Crossfire configuration was also 44% faster than the HD 7750 in Crossfire, which scored 45fps -- 96% faster than a single HD 7750 but not enough to surpass the GTX 560 Ti and HD 6870.
Having just launched on PC, AMD hasn't optimized Crossfire for Alan Wake yet. As a result, the dual HD 7770s were just 64% faster than a single card, while the HD 7750 pair was 85% quicker. Nonetheless, both exceeded the GTX 560 Ti and HD 6870 by a handful of frames.
