Well, performance-wise, you cannot beat Intel and AMD at the moment. Then there is ARM, which is strong, especially if power consumption is an issue. And it is closing the gap to the top. Bonus: ARM has a range from simple M0 cores to GHz multiprocessor chips. Where is RISC-V on that scale?

Compare ARM performance: https://browser.geekbench.com/search?utf8=✓&q=ARM with RISC-V performance: https://browser.geekbench.com/search?q=RISC-V and you’ll see that RISC-V has a looooong way to go before it can be considered relevant.

RISC-V has it’s place, no question, but don’t expect servers or workstations anytime soon. At least outside China and Russia…
