PCI Express feature test
PCI Express (PCIe) is a standard interface that provides high-bandwidth communication between devices in your PC.
New PCIe 4.0 interfaces provide up to twice the bandwidth of PCIe 3.0. With more bandwidth, games can transfer more data,
reduce loading times, and support more complex scenes.
The 3DMark PCI Express feature test measures the bandwidth available to your GPU.
> Measure the bandwidth available to your GPU.
> Test the latest PCIe 4.0 hardware.
> Compare the bandwidth of PCIe 4.0 and PCIe 3.0.
