I'm reading the AT review of the Ryzen cpu's and the chipset slide with specs shows some real limitations that need to be addressed. Their top model X370 cripples 2 sata ports if you run m.2 which is ridiculous. Even my z97 doesn't affect the sata ports when a nvme m.2 drive is used. How are they going to compete with Intel's higher offerings with limitations like these? Who wants to sacrifice sata ports when running a m.2 ssd?
it is an option for the motherboard designer. Through all kinds of settings, different functionality can be routed to the same pins.
If you plug in a x4 nvme, suddenly your 2 sata ports do not stop working.
They are just not there. It says it right there in the notes.
It is just as with microcontrollers and other soc, where an i/o pin can have multiple functionality. Like for example an adc input, a timer output, a pwm output, half of a uart. It is just a software selection.
The motherboard designer decides what will be equipped as hardware and through writing proper boot code in the bios, the functionality of the pins can be programmed.
