I wanted to know if CPU lanes are distributed to components based on priority or are they specified by the motherboard manufacturer? For example, Intel i9 9820x has 44 lanes , and these lanes will first be given to the slotted GPU(s). A single GPU will use a maximum of 16 out 44 lanes, leaving 28 lanes. My question is will all of these 28 lanes used by distributing them to the other components in the PC based on priority level, NVMe instead of SATA, or will only some of the lanes be used by specific slots on the motherboard while the rest of the components going to the chipset?
