UL Releases PCI Express Feature Test For 3DMark Ahead of 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.While real-life gaming performance is unlikely to be limited by PCIe bandwidth, the test does provide a repeatable and reliable way to measure PCIe bandwidth across generations and thereby the performance of different hardware configurations. The PCI Express feature test is available now in 3DMark Advanced Edition and 3DMark Professional Edition and is compatible with any system that has a Direct X 12 compatible discrete graphics card. The test will not run on systems using integrated graphics, and on multi-GPU systems, only the primary GPU will be tested. External GPU enclosures are not supported either.

Horrible encoding is horrible.
Perhaps it might reveal weakness in other components that could cause stuttering
It starts with fewer big polys and then goes up, on my gen 3 PCIe it looks quite nice at the end, on gen 4 it should be quite convincing field of grain :)
I know oc'ing the PCI-E bus helps the videocard but can cause issues for the NIC, S-ata controller and what more. But we've done it in the past to sqeeze a few more FPS out of a OC contest.
Modern graphics cards are proven to be effective enough to run on 3.0x8 with single digit performance loss.
The only "4.0 beats 3.0" scenario is external display card, but it is a very niche market .
Please stop doing these stupid PCI-E 4.0 graphics benchmarks.
Something looked like a AIDA64 memory test would be fancy enough for a bandwidth test.
And I have to remind you, this test isn't a PCI-E test because it needs a GPU to operate.
For example you cannot test your fancy PCI-E 4.0 x4 m.2 slot with it.
You can call it a "GPU data rate test" but PCI-E ? Hell NO.
It is a pointless test at the beginning and calling it a PCI-E bandwidth test is utterly stupid.
108 intel ruler SSD's in there, offering a total capacity of 864GB and speeds of 30GB a second read/write. That's ten times the speeds of an high-end SSD for consumers right now.
