The power is secondary. There are many x86 processors that can compete with Apple Silicon for compute, even in a laptop, and my desktop can crush a Mac Studio/Pro easily even though it isn't strictly top tier. What Apple has is great power and superb efficiency. A Macbook Pro can work literally all day, 16+ hours, while a Windows laptop doing the same work will drain its battery in two or three hours. And work in this case means the same as "game", computer doesn't care whether the math it's doing is being put into something productive or something entertaining. In mobile platforms, as compared to competing Windows products, Apple offers high-tier performance and absolutely unrivalled efficiency. Windows laptops that match it in battery life have so little performance they're barely usable even for just web browsing, and Windows laptops that match Apple in compute/graphics don't have anywhere near the battery life.
With a macbook, I can unplug from the wall, go to work, work all day, come home, watch films or game all evening, and only plug back into the wall overnight. With a Windows laptop I have to plug into the wall for half an hour every two hours. My 7840HS laptop can match a macbook in pure compute/game metrics, but battery life is a huge part of a quality laptop, and it just comes nowhere near being able to compete. The macbook can match it in performance, all day long. The x86 laptop conks out after just a few hours. And that's despite the 7840HS having a node advantage, TSMC 4nm vs TSMC 5nm. M2 Pro is just that much better.
