Take a laptop with a mobile graphics card. Mobile graphics cards obviously perform worse than their desktop counterparts. I would say they perform like the next lower tier on desktop (e.g. an RTX 3080 Mobile performs about as good as an RTX ~~3070~~ 3060TI desktop card according to UserBenchmark (yeah, I know, not the best site, but close enough in this case). But the mobile card still only less wats.

This laptop uses a 200 watt charger. How can a 200 watt charger power a 3070 and an i9 processor? Even if they are just the mobile variant, isn’t that almost like expecting a 200 watt power supply to run a 3060 TI and an i7 processor from the same generation? Heck, we don’t even run 75 watt cards like GTX 1650s and 60w CPUs like some i5s and i3s on 200 watt on desktops. So what gives?

a 3080 mobile is not as good as a 3070 desktop. It’s not even the same league. A simple 3070 is tripple the size in height as the laptop. It’s the same chip running on 30% clock rates. Gaming Notebooks are a marketing thing. Buy a Gaming PC + a normal Notebook and you’re mostly cheaper than a gaming notebook (ok, not today..but when prices are back to normal). So they get descent performance (for a notebook) but not even close to the desktop counterpart – you can’t even compare them directly. If a rtx 3080 would fit in 5mm height with horrible cooling – the desktop versions wouldn’t take giant amounts of space the tower.
