The graphics card, an Amd RX Vega 8 (Ryzen iGPU), is nowadays quite passable. We could say that in the middle range. You will be able to watch Youtube / Netflix/etc... in good quality (1080p or more) and you will be able to play comfortably the majority of games.
More exactly it is the 292 of more than 600 graphic cards.
Oh and be aware, if you're still using jack/mp3 connector, this model DOES NOT have it.
With that weight, more than portable, it is draggable. As long as your intention to move it does not pass from the desk to the sofa, it will do.
