Best laptop for COD: MW2

I usually game on my home PC but recently I've needed to be away from home for an extended period of time. I want to pick up a laptop to play COD:MW2, Apex Legends and some other titles. I've never gamed on a laptop before. From what I understand, the graphics cards on gaming laptops don't lineup with their desktop counterparts. Does anyone game on a Legion Pro 7i Gen 8? if so, what sort of frame rates are you getting? Are they comparable to desktop machines?
