UL frigiver PCI Express-funktionstest til 3DMark foran PCIe 4.0-hardware

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. Selvom virkelige spilpræstationer sandsynligvis ikke vil være begrænset af PCIe-båndbredde, giver testen en gentagelig og pålidelig måde at måle PCIe-båndbredde på tværs af generationer og dermed ydeevnen for forskellige hardwarekonfigurationer. PCI Express-funktionstesten er nu tilgængelig i 3DMark Advanced Edition og 3DMark Professional Edition og er kompatibel med ethvert system, der har et Direct X 12-kompatibelt diskret grafikkort. Testen køres ikke på systemer, der bruger integreret grafik, og på multi-GPU-systemer testes kun den primære GPU. Eksterne GPU-kabinetter understøttes heller ikke.
