This content requires the base application 3DMark on Steam in order to run.

## About This Content
PCI Express (PCIe) is a standard interface that provides high-bandwidth
communication between devices in a computer. New PCI Express 4.0 interfaces
provide up to twice the bandwidth of PCI Express 3.0. With more bandwidth,
games can transfer more data, reduce loading times, and support more complex
scenes.

This 3DMark feature test measures the bandwidth available to your GPU over
your system’s PCI Express interface.

* Measure the bandwidth available to your GPU over PCIe.
* Test the performance of the latest PCIe 4.0 hardware.
* Compare the bandwidth of PCIe 4.0 and PCIe 3.0 interfaces.
