Sipeed LM4A – T-Head TH1520 RISC-V module to power Raspberry Pi 4 competitor and cluster board
I’m sure some will say the Dhrystone benchmark is outdated and susceptible to compiler flags, and those are true statements, but Dhrystone and CoreMark are the only results we have here for now. The LPi4A’s C910 core is shown to have similar performance or even higher than the Raspberry Pi 4’s Cortex-A72 core. The RISC-V board was only running at 1.85 GHz, so performance should scale if the processor can indeed be clocked at the advertised 2.5 GHz. Both the RV64GC toolchain and an optimized toolchain was used in CoreMark, but it’s unclear what the optimized toolchain does. There may be more details in the Yocto Linux BSP for TH1520 hosted on Gitee.
