In terms of current chips they're the best part of a decade away. You can't buy a RISC-V processor competitive with a good arm chip let alone an X86 or a really good arm chip like M1 Current cores, however, are fairly competitive in terms of perf per MHz, but this has to be taken with a grain of salt because the proof is in the taste not the ingredients.
