Sorry, you're right, I meant "integrated graphics". Those (often laptop) chips that don't have real GPUs with SOCs, or whatever, but just have some helper commands/functions for common graphic processing tasks. Basically, the kinds of chips that only do linear (threaded) processing, even if it's on rendering functions.
I'm not aware of any "integrated graphics" which is not also a full GPU. Unless you talk about 15 year old laptops.
Can you give some examples of such chips/laptops? As far as I'm aware Windows requires at least full DirectX 9 compatibility before being able to use hardware acceleration for it's composited desktop.
