Rhino 6 Integrated vs Dedicated Graphics Performance

I’m having a devil of a time trying to decide on which Windows laptop to get to run Rhino 6. (I’ve been running Rhino 5 on my Mac on Parallels with great success up to now, but no more for Rhino 6.) My big question is how much of a performance difference, approximately, am I going to see between an integrated Intel UHD Graphics 620 and, say, a dedicated NVIDIA GeForce MX150?

I’m not planing on doing massive complex renderings or movies.

Any thoughts anyone can share?
