3DMark PCI Express feature test

PCIe bandwidth test

3DMark PCI Express feature test is a PC hardware benchmark that measures the bandwidth available to your GPU over the system’s PCI Express interface. You run the test to check how much bandwidth the connection provides.

PCIe 4.0 and 3.0

The test covers PCIe 4.0 hardware and lets you compare its bandwidth with PCIe 3.0. PCIe 4.0 provides up to twice the bandwidth of PCIe 3.0.
