Steam deck equivelant as laptop

I do all of my gaming on the steamdeck and love it.

I need to buy a laptop (ideally a 2 in 1 tablet thingy) partially for work but also for entertainment when it isn't practical to lug the deck around separately.

It's been years now since I've had a PC or laptop, I wanted to ask performance wise what sort of spec would I need to be looking for to get a similar gaming performance as I get from the deck?
