What do you think of notebooks without a graphics card from Nvidia or ATI? So onboard? Are they good for what?
To work in any case and with the ryzen igpus, you can also gamble very reasonably, at least with the 4000s
For everything except 3D applications: Yes.
It depends on what you want to do. In normal office applications this is enough as soon as it becomes graphically demanding, they run very hot…
Such laptops are certainly also useful. You don't need a dedicated graphics card for office applications. An integrated graphics unit may also have sufficient performance for a little more demanding applications. Here you would have to know exactly what the application is about. Games, for example, can sometimes be played when the system requirements are low.
Sure they are good as long as you don't want to play very demanding games
