PCIE
n.n. Stands for Peripheral Component Interconnect Express. A fast way for a computer to connect to parts like graphics cards or storage drives inside the machine.
n. Abbreviation for Peripheral Component Interconnect Express. A high-speed serial computer expansion bus standard designed to replace older standards like PCI and AGP, providing higher bandwidth and lower latency for internal hardware connections.
You need a motherboard with a PCIe slot for that graphics card.
Modern gaming PCs require at least one PCIe x16 slot to handle the massive data throughput of high-end video cards.
The transition from PCIe 4.0 to 5.0 effectively doubled the available bandwidth per lane, allowing for significantly faster data transfer rates in enterprise-level solid-state drives.
Often used as a modifier before another noun, such as 'PCIe slot' or 'PCIe lane'.
