  Here is the conclusion from the article: "Across 71 benchmarks ran across all three Scaleway Elastic Metal instance types, the EM-RV1 was much slower than even the aging Intel and AMD x86_64 instances. The EM-A315X that is using a 10 year old Ivy Bridge Xeon with 4 cores was around 7.4x the performance of this RISC-V cloud server. Or the half-decade old Ryzen 5 PRO 3600 within the EM-A210R instance was 18.3x the performance of the EM-RV1. Comparing to the very latest Intel and AMD CPUs would be even more mind-boggling advantages for latest x86_64 performance over RISC-V. See all the benchmarks in full here.

  The Scaleway Labs EM-RV1 is interesting for a number of reasons as noted and a great way to dabble with RISC-V cheaply in the cloud, but do so with realistic performance expectations."

  Basically, the reviewed RISC-V chip is not competitive because it is a about seven times slower than a 10 year old Intel chips. My guess is its performance per WATT is lower than current chips from AMD, Intel, and ARM.

  This is relatively boring, as machines with this CPU core have been available for years.

  Looking forward to something new. BPI-F3 ships this month with a 8 core CPU that implements RVA22 and RVV 1.0.

  Milk-V Oasis ships later this year with 16x SiFive P670, which are comparable to Cortex-A77, and thus faster than any ARM SBC that can be bought right now.

  They'll be exciting to look at.
