I can't answer for specific systems but in general the important things to know are

- Intel laptop processors come with various 'TDP' values reflecting their thermal power. The lower the TDP the less time the processor can sustain running a heavy workload but the lighter the laptop. For casual use and general office use the machine is basically idle all the time and bursts to full speed briefly, gaming is different so the higher TDP and heavier laptops tend to perform better
- Intel on chip graphics totally suck for gaming (again great for office use). The latest ones on some of the chips merely mostly suck, and it's not entirely consistent that newer CPU has better graphics.
- AMD on CPU graphics suck a lot less but they won't handle more demanding games on high settings

So in general - for gaming - you go for a heavier system with discrete graphics and probably poorer battery life. The extreme being things like some of the ROG Strix systems with a desktop AMD Ryzen and an underclocked RX580. 2 hour battery life, can also be used as a hairdrier 8)

Desktop systems are generally better than laptops because there is no power restriction, no space restriction and thus you can vent vast amounts of heat. Desktop processors go up to about 135W TDP plus 300W or so for a GPU. If you put that in a laptop it would simply melt. In addition you can swap more parts. The RX3060 in the latest top end gaming laptops will be obsolete within 5 years probably - can you swap it ?
