A laptop RTX 4060 is not a desktop RTX 4060, and treating them the same will cost you. Power limits and cooling decide real laptop performance, so judge your laptop as its own machine.
Score your laptop as its own category, never as a desktop card. If it comes back close or weak, fix power mode, cooling, RAM, and storage first. Only buy a new laptop when the GPU itself is the wall, because you cannot swap it.
Do not buy on a guess. Check your exact setup in 60 seconds and see the one part that matters.
