Vapour chambers in consumer tech very much are new. Outside of a the occasional pointless part they haven't actually featured in consumer electronics due to high cost and lack of use case (low power densities or low overall power dissipation requirements).
Comparing them like heatpipes is like comparing a tractor to a Lamborghini, they both have 4 wheels, an engine, and are even built by the same company. But there are some subtle differences relevant to where you may consider using one or the other.
Yes they do. Basically none have vapour chambers in them. They are NOT the same thing just because they work on the same principle. Vapour chambers have featured in Intel Itaniums, Asus ROG mobile phones, and Sapphire Vapor-X GPUs (for marketing purposes, not because they were necessary). Very recently they have started becoming necessary and that has largely been the shift to 7nm concentrating power density. You will find an occasional laptop with a vapour chamber, but only high end ones due to their desig
New form factor, sure - same principal, moving heat in a closed system using evaporative cooling and a capillary system to move fluid. Even most of the materials are the same, its just different construction.
A tractor and a sports car are also based on the same principle, hell they are even made by the same company. Both have wheels internal combustion engines, complete with cylinders, most of the same components including differentials, cooling systems. You don't consider them the same thing do you?
Construction matters and makes differences that exceed orders of magnitude. Vapour chambers can move heat an order of magnitude more effectively than a heatpipe. They also can't move them very far as they rely on surface area. Heatpipes are not dependent on surface area for the applications and are poor at moving large quantities of heat and instead can move them large distances (I specified a 5m long heatpipe in one project, a vapour chamber tops out at moving heat 1-2mm).
Simply converting a heatpipe to a flat shape and calling it a vapour chamber will very quickly show you just how different they are internally when your attempt crushes on one side from mounting pressure and bows on the other due to thermal pressure.
They are as much of a different construction as a Lamborghini Aventador and an Lamborghini Spark VRT. Actually even more different considering both the tractor and the sports car have the same engine displacement and are in the same order of magnitude for engine power.

Sigh, nothing new here.

What? Every laptop I've had for the last decade (or more) has a heat pipe in it. You must have a narrow definition of consumer electronics.
