RISC-V chips like the processors are starting to show up in low-power, open source computers like the HiFive Unmatched and Nezha as well as educational products like the BBC Doctor Who HiFive Inventor. Pine64 even uses a RISC-V processor for its Pinceil soldering iron.
So far most RISC-V chips are designed for low-power, embedded applications. But that could change in the future.
A new RISC-V Special Interest Group for High Performance Computing (SIG-HPC) is looking into what it would take to expand RISC-V architecture so that it would also be a good fit for supercomputers and other high-performance systems used for artificial intelligence, deep learning, and machine learning.
