If by disparity you mean sometimes Windows is better and sometimes Linux is better. I have one of those GPUs. Give it a try before you slam it. Valve has thrown so much money into Proton that support is amazing compared to when I tried a decade ago.
Benchmarks are readily available, I have a 5080. Some DX11 and older games do run slightly better on Linux. But a lot of them don’t. And pretty much 100% across the board DX12 games run 10-30% slower on Linux compared to Windows. Nvidia has even acknowledged the issue and claims to be working on a solution.
