MacBooks don't have real GPUs either (I assume you mean Macbook Pros). Running the default HDRP Unity scene on a MacBook Pro runs around 30fps, Running on a 3yr old Razer 1060 runs at 180fps.
I use my MBP more than my Razer but I'm disappointed Apple no longer makes the power house laptops they used to.
