PCIe 3.0 x4 == PCIe 2.0 x8 == PCIe 1.x x16 m 0 l CDdude55 a b V Motherboard December 12, 2012 5:09:37 PM It's really just used as a letter to mean "by". Some people will read it as "PCI-E by 16" and some people just say "PCI-E x16"(they say "x" instead of "by"). I guess you could say that "by" is a better way to put it, as the number followed after it indicates PCI-E lanes which determine bandwidth. m 0 l Related resources PCI-E x16 (Compatible) what does this mean? - Forum What does it mean that a "PCI-Express 3.0 X16 Slot runs at X8"? - Forum What does it mean that my VGA card is x16 - Forum Pcie x16-what does this mean? - Forum What does pcie x8/x16 mean on an ICH0R MB? - Forum Can't find your answer ?
