NVIDIA GeForce RTX 5090 PCI-Express scaling (www.techpowerup.com)

The new NVIDIA GeForce RTX 5090 is the first high-end graphics card that makes use of a PCI-Express 5.0 bus interface. Are you in trouble when try to run it on PCIe 4.0? What about x8, like when an SSD is using up some bandwidth? We've also tested various PCI-Express 3.0, 2.0 and 1.1 configs to get a feel for how FPS scales with bandwidth.

Good to know that PCIe 2.0 x16 respectively 3.0 x8 is still enough for pretty much anything less than a 5090 class card. Except for specific, comm heavy workloads maybe
