is intel uhd graphics 620 good for the sims 4?
Yes, you will be able to play the Sims 4 with that laptop. The following video is Sims 4 (base game it seems) being played on a 7th gen Core i3-7100u and the Intel HD 620 graphics core. The game settings are 1366x768 (the max resolution of that laptop) and medium graphic settings.
