What? Absolutely not. A Turing GPU like your 2080Ti has full DX12 Ultimate featureset, hw accelerated Raytracing, AI acceleration and DirectStorage support. It is light years ahead of RDNA1. Light years. Seriously, it is like comparing a modern Ampere GPU to the Fermi architecture. Expect performance gap to wide far more in the future and even the smallest Turings are going to outperform the 5700XT (actually that is already happening with DLSS and of course RTX) But even without DLSS and RT, once games start using Sampler Feedback, VRS, DirectStorage for SSD data streaming, neural networks for physics and AI via directml, and Mesh Shaders, the 5700XT will suffer dramatically. PCIe4 doesn't matter in that case.
