I'm a first time PC builder. I'm looking at mainboards. Some mainboards say they have a "PCIE 4.0 x16 (x4)" connection. I know what PCIE 4.0 x16 is but the (x4) confuses me. (Example mainboard: MSI PRO B760-P WIFI DDR4)

Does that mean that that particular PCIE slot will be x16 in length but can only run at x8x4 speed? Some mainboards even have PCIE 3.0 x16 (x1) at which point I'm asking myself why even use the manufacturing material to make the slot that long only for it to supportbe able to use x1 speed. at max.
