PCIe (Peripheral Component Interconnect Express) is a high-speed interface standard that connects peripherals, such as graphics cards, storage devices, and network cards, to a computer's motherboard. The PCIe specification defines the architecture, protocols, and interfaces for these high-speed connections. pcie spec
: Each new generation of the spec typically doubles the bandwidth of its predecessor. For example, PCIe 4.0 offers double the throughput of 3.0, and PCIe 5.0 doubles it again, providing the low latency necessary for modern gaming and AI workloads. : A key feature of the spec is
The Peripheral Component Interconnect (PCI) Local Bus was introduced in the early 1990s as a replacement for the ISA and EISA buses. It evolved over time, increasing in width from 32 bits to 64 bits and increasing in speed from 33 MHz to 66 MHz, and eventually 133 MHz with PCI-X. While PCI and PCI-X served the industry well for over a decade, the inherent limitations of a parallel bus architecture (such as loading, signal integrity, and clock skew) made it difficult to scale to higher bandwidths.
