Why Is My System Reporting PCIe Gen 1x1 Instead of the Actual PCIe Configuration for My Intel® Arc™ Graphics Card?

Environment

Operating System

Windows® 10*, Windows 11*, Ubuntu 22.04

Description

Due to the PCIe hierarchy of the Intel® Arc™ Graphics Cards, standard operating system tools such as the Windows* Device Manager and the Linux* console lspci command, will not show the device’s actual PCIe port speed (specifically the PCI max link speed and PCI max link width) information of the graphics device properly. They will always show Gen1 and x1 lanes instead of the expected product information, for example such as Gen4 and x16 lanes for the Intel® Arc™ A770 Graphics card.

Resolution

It is important to remark that this does not affect the PCIe port speed, and it does not affect the card’s operation or its performance. There is no PCIe standard-compliant way of resolving this at the moment. Instead, and as a workaround, we recommend using tools (such as GPU-Z) with other means to retrieve this information and show the correct values.
