I don't see any downside of having a dedicated graphic card because it only works when needed.

The 'downside' is that if an app 'needs' the GPU it will get switched on, and when it's on... it's on and thus consuming more power even when it's hardly being used.

So the downside is slightly reduced battery life, and not always with the benefit of noticeably increased performance.
