"From what I've seen of people running Linux on these things, it is definitely not something you'd want to develop on"

Can you please elaborate? I'm a programmer with a linux framework laptop (NixOS specifically).

The JH7110 is a multi-year-old SBC that is slower than a Raspberry Pi 3 is. It does not have many extensions for things people today take for granted (no hardware crypto for instance is in practice a massive loss.) So, if you're OK with that, then it will be fine. But most people probably aren't interested in making their expensive laptop perform worse than a 15-year-old device in every way.

It's slow to the point of being outpaced by an ARM SBC from 2016, and it's not even current with today's RISC-V spec. This is a curiosity, nothing more, but it will still be far and away the nicest (but not the only!) RISC-V laptop. Give me a Pi CM5 + 16GB RAM Framework motherboard carrier and I'll get out my credit card.

Completely ridiculous benchmarks for what people will use this board for. The xz compression and SQLite are the only slightly relevant tests -- and on those it's pretty close to a Pi 400.

Comparing an 8 GB JH7110 board to a 1 GB Pi 3 is beyond ridiculous. The Pi might win a few micro-benchmarks that use NEON, but not general purpose C code, and in real use 1 GB is incredibly limiting.

All Arm SBCs at present as far as I know -- certainly including the Pi 5 and RK3588 boards (Rock 5 etc) -- are far behind the current Arm ISA, as they implement ARMv8.2-A from 2016. And none of them even have the optional SVE vector ISA that was defined as part of ARMv8.2-A.

In contrast, the JH7110 implements mid 2019 RISC-V specs, plus some things from late 2021 (e.g. Zba and Zbb).

The SpaceMIT 8 core SoC in the BPI-F3, Muse Book and others being released now implements RVA22+Vector ratified in March 2023. The Canaan K230 (on e.g. the CanMV-K230 board) also implements the same RVA22+Vector spec.

Late this year the 16 core ~2.5 GHz P670 (A78-class) SoC will leapfrog anything available on currently known Arm SBCs. Milk-V say the base model of their Oasis SBC will be $119. Sipeed says a fully-kitted board will be $300.
