3DMark PCI Express feature test

About the 3DMark PCI Express feature test

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.
