Power efficiency. Arm promises the same performance at lower temps and wattage than x86 at competitive price points. That's a really attractive proposition for the laptop market. x86 can be as small format, as power efficient, as cheap, or as powerful than ARM but not all at the same time.
That's not true at all. It's a common misconception but there's nothing stopping x86 from also targeting a power efficient design. It's all about architecture and not the instruction set. There just hasn't been an incentive for Intel and AMD to focus their architectures on power efficiency since they make much more money in the server space. Lunar Lake is Intel's first real attempt at it.
The Z1 Extreme has already shown very comparable and sometimes better performance and power efficiency as the M2 chips and the Lunar Lake chips trade blows with the X Elite not just in performance but also power draw.
If you wanna know more, this goes very in depth on what the differences are: https://chipsandcheese.com/p/why-x86-doesnt-need-to-die
I agree it is not because they can't but because they didn't want to. But the truth is they haven't. Current offers match exactly what I have described in my comment. Intel and AMD have been sleeping on their laurels and ARM is coming for their lunch unless they move quick.
