The slot that is currently in use is the slower one since it’s only Type: x1. Depending on what you use the slot currently (such as an M.2 drive), you might wanna switch slots so you can take advantage of the speed; the x1 slot is completely adequate for 1gbps ethernet if you don’t need more. Both slots are otherwise functionally the same, but make sure to look up in your mainboard documentation if there’s any limitation if you use both slots or a specific hardware configuration (mine deactivated the second M.2 slot after changing from an 2600x to an 5950x for example)
