graphic card slot in motherboard

Low profile, 1206 MHz, 4GB GDDR5 ... PULSE RX 550 4G G5 LP. ... PCI Express® 2.0 or higher version based PC is required with one X16 lane graphics slot available on the motherboard in order for the card to be compatible with.

Regardless of the PCI-E revision (be it 3.0, 4.0, 5.0), if I have a x16 PCI-E card, it needs to be in a x16 slot on the motherboard to have it run at its full speed.
