StarFive has launched its 64-bit RISC-V “Dubhe” core with up to 2GHz @ 12nm performance plus Vector and Hypervisor extensions. Meanwhile, the Chinese Academy of Sciences announced a similarly Linux-friendly, 14nm RISC-V RV64GC “XiangShan Nanhu” core that also clocks to 2GHz.

Chinese RISC-V chipmaker StarFive, which recently showed off a VisionFive V1 SBC with a StarFive JH7100 SoC with dual Cortex-A55 like SiFive U74 cores, has announced the “delivery” of its own RISC-V core called Dubhe. In other China-related RISC-V news, the Chinese Academy of Sciences revealed a line of open source XiangShan RISC-V cores that run Linux, including a new, high performance XiangShan Nanhu design (see farther below).
