They're not integrated into the motherboards, they're built directly into the CPU. This reduces power consumption and allows the motherboard to shrink, no separate component needed.
The HD4000 isn't the most capable chipset on the market but for most applications, light-duty use, it's fine. Even the basic versions of this chipset could support two 24" screens without much trouble. Just don't expect benchmark-shattering 3D performance.
