The H310 chipset provides 6 x PCH PCI-E lanes, while the B365 chipset provides 14 x PCH PCI-E lanes. The number of I/O lanes is higher on the B365 chipset, providing 30 lanes against 14 found in the H310 chipset. An advantage of the H310 chipset is that it supports wireless AC, so you won’t have to buy an aftermarket network card if you want WiFi in your system.
