It's possible to have such a graphics system and not know about it.
For instance nVidia GTX xxxM (where xxx is a normal nVidia graphics
system model), have an Intel chip as the front end.  These are called
Optimus, and are made mostly for laptops.  The idea being that if you
don't need the grunt of the nVidia side of things, they just run the
Intel side of things, using less power, making your battery life
longer.  The "M" at the end is a dead give away, even if otherwise
never mentioned.

Oculus Rift developers are having a hard time with these, as Oculus has
dropped support for them, though laptops are popular for demos, coz
it's easier to carry one around.  I had a hard time with one, before I
discovered that the client will be using laptops for their Rift stuff,
so we decided to stick with the last Rift SDK that supported nVidia
Optimus.

I have no idea what the ATI versions are like.
