My guess would be partially because there are fewer possible interfaces, and they’re directly connecting the CPU to a separate Ethernet/WiFi MAC, USB hub controller, and audio DSP rather than having a separate chipset arbitrating who’s talking to the CPU and doing some of those functions?
my understanding, from the block diagrams they release, is that these io functions are simply integrated into the cpu. in a way that could probably be implemented in desktops too.
I haven’t looked that closely at laptop CPUs
