PCI Express Version

PCI Express Revision is the supported version of the PCI Express standard. Peripheral Component Interconnect Express (or PCIe) is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. The different PCI Express versions support different data rates.

3.0

PCIe Version

PCI Express is a high-speed serial computer expansion bus standard used for connecting high-speed components, replacing older standards such as AGP, PCI, and PCI-X. It has gone through multiple revisions and improvements since its initial release. PCIe 1.0 was first introduced in 2002, and in order to meet the growing demand for higher bandwidth, subsequent versions have been released over time.

Max Number of PCI Express Lanes

A PCI Express (PCIe) lane consists of two differential signaling pairs, one for receiving data, one for transmitting data, and is the basic unit of the PCIe bus. Max # of PCI Express Lanes is the total number of supported lanes.

Instruction Set

An instruction set architecture (ISA) defines the instructions a processor can execute. Common architectures include x86-64, ARM and RISC-V. The ISA determines software compatibility, while optional instruction extensions add specialized capabilities.
