Considering the virtual non-existence of native Windows ARM apps right now, x86 benchmarks would be far more interesting on this thing, to get an idea of how it will perform in the real world, since the vast majority of software users will run will be emulated.
Right now, it's true that there are a handful of apps that are ARM native, but in many cases it won't be the software that people normally use. Asking somebody to change all their software to unfamiliar equivalents is a serious knock against a product, and is in some ways worse than a Windows user and giving them a mac: at least they can run most of the same software they're familiar with on the mac.
When I think of the software that I use on a Windows machine on a regular basis (Chrome, Discord, Photoshop, Netflix, Visual Studio, Media Player Classic Home Cinema), none of them are currently available as ARM native, AFAIK. Ironically, Visual Studio can compile to ARM64, it just can't run directly on it.
