It is the common motherboard interface for personal computers' graphics cards, hard disk drive host adapters, SSDs, Wi-Fi and Ethernet hardware connections. Those same video cards can work in earlier chipset motherboards, but will be slowed down to 2.0/2.1 speeds.PCI Express ( Peripheral Component Interconnect Express), officially abbreviated as PCIe or PCI-e, is a high-speed serial computer expansion bus standard, designed to replace the older PCI, PCI-X and AGP bus standards. But those version 3.0 video cards can only operate at PCIe 3.0 speeds when used in a latest generation Intel Z77 chipset motherboard.
PCIe cards are now mostly designed according to the PCIe 2.0 or 2.1 standard, with the exception of some of the latest generation PCIe 3.0 video cards that are available. Incorrect: you're confusing 2 different standards going by similar sounding names. Those would see a speed downgrade, if compared with one of the newer PCIe cards. The best USB 3.0 chipset for such a card seems to be made by NEC/Renesas.Īlso: there do exist USB 3.0 add-in cards that utilize the older PCI card design. 2.0) USB 3.0 add-in card should indeed function at full speed when inserted into a PCIe 1x slot. The 8x & 16x slots are physically the same, but can differ according to the motherboard chipset resources that are available. However: PCIe slots are available in PCIe 1x, 4x, 8x & 16x sizes.
