As I understand, that is to be expected because PCIe GPUs get 16 lanes, which is more than enough. There's more to PCIe than just graphics cards. SSDs, Thunderbolt, 10G Ethernet, USB 3.1-2 are some bandwidth demanding applications that could benefit PCIe NVME drives only get 4 lanes through the m.2 port, and drives run close to the bandwidth limits on 3.0, I think I've seen benchmarks showing 30% improvements on 4.0 compared to 3.0 I'd also be interested in what difference there is running a PCIe 4.0 graphics card with only 8 lanes on 4.0 vs 3.0

> I'd also be interested in what difference there is running a PCIe 4.0 graphics card with only 8 lanes on 4.0 vs 3.0 it's measurable, but not very significant. take a look at these charts: https://www.techpowerup.com/review/nvidia-geforce-rtx-3080-pci-express-scaling/27.html https://www.techpowerup.com/review/nvidia-geforce-rtx-3080-p... (pcie 2.0 x16 is equivalent to or slightly worse than pcie 3.0 x8)
