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.

Gen 3, 16 Lanes (CPU only)

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.

64-bit

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.
