PCI Express Insights

What is PCI Express?

PCI Express (PCIe) is a high-speed serial computer expansion bus standard, designed to replace the older PCI, PCI-X, and AGP bus standards. It is commonly used to connect graphics cards, network cards, storage interfaces (such as SSDs), and other high-performance peripherals to a computer's motherboard. PCIe offers significantly improved bandwidth and performance compared to its predecessors.
