Peripheral Component Interconnect Express (PCIe)
pcPCIe is a high-speed interface standard for connecting peripheral devices to a computer's motherboard.
expanded
Peripheral Component Interconnect Express (PCIe) is a prevalent interface standard used in computing systems to connect devices like graphics cards, solid-state drives (SSDs), and network cards directly to the computer's motherboard. It facilitates communication via point-to-point serial connection, allowing multiple lanes (x1, x4, x8, x16) to be combined for increased throughput. PCIe's scalable architecture makes it integral to modern computing, enabling high data transfer rates essential for applications requiring substantial bandwidth.
examples
The NVIDIA RTX 4090 graphics card uses a PCIe 4.0 x16 slot to achieve up to 64 GB/s data transfer rates, enabling high-performance gaming and computational tasks.
Widely employed in gaming desktops and workstations to provide rapid data exchange between the GPU and CPU.
The Samsung 980 Pro SSD utilizes a PCIe 4.0 x4 interface to deliver sequential read speeds up to 7,000 MB/s (approx. 6.8 GB/s), markedly improving storage performance in data-intensive applications.
Frequently used in high-performance computing environments where rapid data retrieval is critical, such as database servers and video editing systems.
The Intel X540 network adapter employs a PCIe 2.1 x8 interface, providing a bandwidth of up to 40 Gb/s, used in enterprise networking setups that require robust data throughput.
Commonly utilized in data centers and enterprise server configurations to facilitate efficient network communications.
