An Ampere or other Arm server chip would fit the bill. Aside from Apple, no one is making arm chips to serve the laptop/desktop segment. So there's this HUGE gap between the endless sea of embedded/mobile Arm chips and then jumps to a handfull of mega-many-core server chips.
Apple is finally filling in one of the Arm gaps with a mid-tier chip that can handle a desktop load efficiently while an efficient GPU can handle graphics without thermally clobbering each other.

You can argue that their chips in this segment are not very good, but Qualcomm is actually specifically addressing the laptop market, and they're not "no one".
