Question

Iron

The specifications of the intel core i9-10900F processor indicate that it has 16 lines

Let's say I put a video card in the 16x slot and a sound card in the 1x slot into the GIGABYTE Z490 GAMING X motherboard. Following the description of the processor, will it distribute lines 8-8? I read somewhere that the chipset has its own lines. Then the processor will give 16 lines to the video card, and the sound card will be controlled by the chipset? In general, how does it work?

Answer 1

This board has the ability to configure several PCI Express 16 in 16-4 format, therefore, instead of 8-8 configuration, it will be 8-4.
