Better integrated graphics than most of Intel's offerings (HD4000 come close to some of the mid level APU's though).
If you can't afford to or just don't want to use a dedicated GPU, but you still want to play games, an APU is the best way to go. The CPU portion isn't as strong as anything Intel offers, but the IGP makes up for it, to an extent.
If you don't care about gaming, anything with integrated graphics will do.
