Nobody expects RISC-V to beat i7 or Ryzen in any benchmarks.
IMO its purpose is to be the in hardware what GNU/Linux was in software.
edit: GNU/Linux, not just Linux :)
Crusoe and ARM were not about the promise of better performance, but of being much more energy-efficient for the intended purpose (though since a few years ARM tries to get into a (more) high-performance field).
What I wanted to say is that the major selling point of RISC-V would be its open-ness rather than anything performance (or power) related. In that respect it has already captured the attention of interested parties, regardless of that the actual performance will be.
