Initial Benchmarks Of The SpacemiT K3 RVA23 RISC-V CPU With The K3 Pico-ITX
For getting an initial idea of the SpacemiT K3 computer performance across a range of workloads, I compared the performance to the SiFive P550 Premier as the fastest SBC/developer board offering from SiFive to this point. Plus benchmarks alongside the recently reviewed Loongson 3B6000 as that recently reviewed Chinese 12 core / 24 thread processor, Plus for reference to the ARM performance was the Raspberry Pi 500+ with its four 2.4GHz Arm Cortex-A76 CPU cores. And then for x86_64 perspective were various current-generation Intel Core Ultra and AMD Ryzen 9000 series desktop processor all tested on Ubuntu Linux.
This is just the initial benchmarks with my testing of the K3 RISC-V SoC over the past week. More benchmarks to come, including AI and more. For AI there is Llama.cpp in the Bianbu repository as SpacemiT's preferred path for using Llama.cpp on the K3 SoC as for the best performance you need to be using their proprietary toolchain that is based on GCC and doesn't appear to be publicly available yet. With this SoC is the likes of the xsmtvdot vector dot product extension for helping with AI workloads, but unfortunately not yet in upstream open-source compilers at this time.

With this initial benchmarking is a range of different workloads tested across these systems. Unfortunately with the K3 there was no Linux PowerCap/RAPL driver or HWMON driver for exposing the SoC / CPU cores power consumption data so there isn't any power / performance-per-Watt metrics in today's articles. So just treat this initial batch of numbers as a "preview" of the SpacemiT K3 Linux capabilities.
