I haven’t looked that closely at laptop CPUs

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 can’t say for all of them, I just knew that e.g. the z790 chipset still ran the ethernet phy, audio dsp, SPI, their version of TrustZone, etc through the chipset

If you have the block diagrams for the laptop ones, I’d be curious
