> It's more bandwidth to the chipset, meaning you can run double the PCI 3.0 gear off of that chipset than you could before without hitting a bottleneck Not necessarily the case in practice since that would require some sort of chipset or active converter exposed by the motherboard to mux 3.0 lanes to bifurcated 4.0 lanes. A 3.0 x4 device still needs those four lanes to get full speed so in a PCI-e 4.0 setting you’ll actually be using up four of the PCIe 4.0 lanes, but inefficiently. |
