Nvidia RTX 3080: PCIe 4.0 vs 3.0 scaling analysis

Tom Clancy's Ghost Recon Breakpoint is an online tactical shooter video game developed by Ubisoft Paris and published by Ubisoft. The game was released worldwide on 4 October 2019, for Microsoft Windows, PlayStation 4 and Xbox One, (Wikipedia).

Engine: AnvilNext 2.0. We test using the Very High preset, with AA disabled, Vulkan API.

It's more of the same in Ghost Recon: Breakpoint, albeit on a slightly smaller scale. The Intel system outperforms AMD with PCIe Gen4 across every resolution we tested – there's certainly not much in it at 1440p and 4K, but the overall performance crown remains with Intel.

We can see AMD's system doing better with PCIe 4.0 than with PCIe 3.0, but only by a 2% margin at most, resulting in just an extra 3FPS at 1440p.
