Yup. Their best builders run JH7110 (based on the in-order SiFive U74 cpu, RVA20 + partial B) and these are slow, somewhere between rpi3 and rpi4.
This will improve in 2026, with the first chips integrating RVA23 microarchitectures, such as the Tenstorrent Atlantis SoC and development board, with Ascalon, announced for 2026Q2.
