3DMark feature tests are special tests designed to highlight specific techniques, functions or capabilities.
The 3DMark PCI Express feature test is designed to measure the bandwidth available to your GPU over your computer’s PCI Express interface. This is a synthetic test. In real-world use, your PC’s gaming performance is extremely unlikely to be limited by PCIe bandwidth.

Introduction to PCI Express
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.
