What we see is, that a 3080 is a bit more stable and a little bit faster than a 6800xt. Over all those games together, it is a plus of 9%. That is not a big difference, and it still gives no definite answer to the question "what to buy". Unfortunately they did no tests with an Index and 120hz, nor with a Reverb and a higher resolution.
For this question, you maybe want to take a look at the OpenVR benchmark somewhere at the very end of the main table. Here you will see a very remarkable difference of more than 30% pro 3080!
Why? The developer of OpenVR says:
"Most likely because OpenVR Benchmark internally uses a high supersampling resolution to really put maximum load on the GPUs. The new AMD GPUs have fast cache, but slow memory compared to Nvidia, so the higher the rendering resolution gets, the slower the AMD GPUs become compared to Nvidia. Many flat-gaming benchmarks have shown that the AMD GPUs are very competitive at 1080p, but less so at 4K. And OpenVR Benchmark ends up rendering significantly more than 4K internally, as even an Index at only 100% SS is already more than 4K."

Big Navi vs Ampere for VaM
As many of us are desperately looking for an GPU upgrade for VR, but can't get their hands on a RTX 3080, there are two alternatives on the near horizon. Next week we will learn everything about AMD Big Navi and NVIDIA 3070. According to Igor from IgorsLab, who has stretched his NDA quite a bit...
