PCI Express | Vibepedia

PCI Express, officially abbreviated as PCIe, is a high-speed standard used to connect hardware components inside computers, designed to replace older expansion bus standards such as PCI, PCI-X, and AGP. Developed and maintained by the [[pci-sig|PCI Special Interest Group]], PCIe is commonly used to connect [[nvidia|NVIDIA]] graphics cards, [[creative-technology|Creative Technology]] sound cards, [[intel|Intel]] Wi-Fi and Ethernet adapters, and storage devices such as [[western-digital|Western Digital]] solid-state drives and hard disk drives. With its ability to support faster data transfer, use fewer pins, take up less space, and allow devices to be added or removed while the computer is running, PCIe has become the go-to standard for computer hardware connections. As of 2022, PCIe has become the dominant standard for computer hardware connections, with over 90% of new computers using PCIe connections. The latest version of PCIe, PCIe 4.0, supports speeds of up to 16 GT/s, making it an essential component for applications such as [[artificial-intelligence|artificial intelligence]], [[gaming-pc|gaming PCs]], and [[data-center|data centers]].
