With PCI-Express 4.0 graphics cards and motherboards soon to arrive, UL has released their PCI Express feature test for 3DMark. This latest addition has been designed to verify the bandwidth available to the GPU over a computer's PCI Express interface. To accomplish this, the test will make bandwidth the limiting factor for performance and does so by uploading a large amount of vertex and texture data to the GPU for each frame. The end goal is to transfer enough data over the PCIe 4.0 interface to thoroughly saturate it. Once the test is complete, the end result will be a look at the average bandwidth achieved during the test.
