Re:Ask HN: Why don’t motherboards have GPU and VRAM sockets? by wmf on Saturday January 07, 2023 @03:02PM (#34292048)
There are a variety of GPU configurations. Some use 100 W, some use 450 W; should all motherboards have 450 W VRMs? Memory bus widths vary from 128 bit to 512 bit. And socketed RAM cannot support ~20 GT/s signaling used by GDDR.
