Crossfire x8+x8 versus x16+x16
 

Overall, the change in platforms results in a speedup of only a few percent. Games that ran smoothly before run a little faster, while slower games such as Crysis or Flight Simulator X don’t yet benefit from Crossfire optimizations in the WHQL drivers. Currently, going from x8 to x16 for Crossfire really only offers a tangible payoff in higher resolutions. At the highest resolution of 1920 x 1200 pixels, only a single test enjoyed a really meaningful speedup as a result of the faster interface, going from 53 to 63 fps. The remaining resolutions were already running smoothly at more than 70 or 100 fps, so any improvements here only help the overall performance rating, not real-world playability.
