The pace of RISC-V adoption continues to grow rapidly, yet for the successes enjoyed in areas such as embedded computing, RISC-V is yet to gain ubiquity in High Performance Computing (HPC). The Sophon SG2044 is SOPHGO’s next generation 64-core high performance CPU that has been designed for workstation and server grade workloads. Building upon the SG2042, subsystems that were a bottleneck in the previous generation have been upgraded.
In this paper we undertake the first performance study of the SG2044 for HPC. Comparing against the SG2042 and other architectures, we find that the SG2044 is most advantageous when running at higher core counts, delivering up to 4.91 greater performance than the SG2042 over 64-cores. Two of the most important upgrades in the SG2044 are support for RVV v1.0 and an enhanced memory subsystem. This results in the SG2044 significantly closing the performance gap with other architectures, especially for compute-bound workloads.

RISC-V的采用速度持续快速增长，然而在嵌入式计算等领域取得的成功，RISC-V在高性能计算（HPC）领域尚未普及。Sophon SG2044是SOPHGO下一代64核高性能CPU，专为工作站和服务器级工作负载设计。在SG2042的基础上，上一代中的瓶颈子系统得到了升级。
在本文中，我们首次对SG2044在HPC领域的性能进行了研究。与SG2042和其他架构相比，我们发现SG2044在更高核心数运行时最为有利，在64核上比SG2042高出4.91倍的性能。SG2044中最重要的两项升级是支持RVV v1.0和增强的内存子系统。这使得SG2044显著缩小了与其他架构的性能差距，特别是在计算密集型工作负载中。
