PCIe

(Peripheral Component Interconnect Express)

Peripheral Component Interconnect Express (PCIe) is a high-speed serial computer expansion bus standard used to connect hardware devices like GPUs, SSDs, and network cards to a motherboard. It offers significantly higher bandwidth compared to older standards like PCI and AGP.

PCIe is widely used in modern computing for its scalability and performance. It supports multiple lanes (e.g., x1, x4, x16) to accommodate different device requirements. PCIe is a key enabler of technologies like
NVMe and high-performance computing.
