What is PCIe? Understanding PCIe Slots, Cards and Lanes pcie slot size PCIe is a serial expansion bus standard PCIe slots come in five different sizes: x2, x4, x8, x16 and x32 The number after the x corresponds to the pcie slot cover PCIe Max Payload Size The PCIe Max Payload Size determines the maximal size of a PCIe packet, or PCIe MTU This means that
