I suspect it will all shake out to health competition :)

IIRC Risc-V provides cores, but full SoC requires a lot of other IPR, and the mind even wanders to the possibility of future SoCs with hybrid Arm/R5 core arrays. The field is open. Some companies like Western Digital have been really visible in Risc-V, but what we can learn from the new push in China is really fascinating.

Super interesting as RISC-V is open hardware, if I understand correctly... Having a strong implementation of it could indeed topple ARM...

This has flown under the Western Media radar but may be significant in terms of open hardware licensing. Worth watching to keep track of execution.
“The Institute of Computing Technology at the Chinese Academy of Sciences (ICT CAS) has showcased progress on a fully open-source processor, designed around the RISC-V architecture, which it hopes will offer competition for Arm parts at the performance end of the market. Developed from the opening of a GitHub repository to booting Debian Linux in a matter of months, with work currently progressing on a higher-performance second iteration, XiangShan, or "Fragrant Hills", comes with bold promises […]”
