A 16-core K3 SoC\u003C\u002Fh2>\u003Cp>The headline feature is the Key Stone K3, a RISC-V SoC with 16 CPU cores split between eight X100 cores and eight A100 AI cores. The X100 cluster runs up to 2.4 GHz, which is enough to move the chip out of toy-demo territory and into something that can power a real desktop.\u003C\u002Fp>\n\u003Cfigure class=\"my-6\">\u003Cimg src=\"https:\u002F\u002Fxxdpdyhzhpamafnrdkyq.supabase.co\u002Fstorage\u002Fv1\u002Fobject\u002Fpublic\u002Fcovers\u002Finline-1781176686850-dmcv.png\" alt=\"SpacemiT’s K3 makes RISC-V feel usable\" class=\"rounded-xl w-full\" loading=\"lazy\" \u002F>\u003C\u002Ffigure>\n\u003Cp>That matters because the K3 is not just about core count.

The Intel NUC-sized mini desktop case\u003C\u002Fh2>\u003Cp>Banana Pi also offers the K3-Pico in an Intel NUC-sized case, which makes it feel like a small desktop rather than a developer board. That form factor is useful if you want a neat box for a desk, lab bench, or test rack without giving up the K3’s expansion options.\u003C\u002Fp>\u003Cp>Benchmarking from Phoronix found that this setup can beat the Raspberry Pi 500+ in multiple tests, and it also outperforms the SiFive P550 Premier. Those results suggest the K3 is one of the more credible RISC-V options for users who want visible desktop performance, not just architectural novelty.\u003C\u002Fp>\u003Cul>\u003Cli>NUC-sized enclosure\u003C\u002Fli>\u003Cli>Beats Raspberry Pi 500+ in multiple tests\u003C\u002Fli>\u003Cli>Outperforms SiFive P550 Premier\u003C\u002Fli>\u003Cli>Available through Banana Pi\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>5. The price you pay for RISC-V progress\u003C\u002Fh2>\u003Cp>The catch is cost. The K3 Pico-ITX board was seen on AliExpress for just under £300, or about $400, for an 8 GB version, while the listed RRP is £595, a little under $800. That is roughly twice the price of a Raspberry Pi 5 with 8 GB RAM.\u003C\u002Fp>\u003Cp>So the K3 is not a cheap switch for hobbyists. It is a higher-spec RISC-V system that finally looks usable, but buyers are paying for early access to that usability.\u003C\u002Fp>\u003Cul>\u003Cli>About £300 \u002F $400 for 8 GB on AliExpress\u003C\u002Fli>\u003Cli>RRP of £595, near $800\u003C\u002Fli>\u003Cli>About 2x a Raspberry Pi 5 with 8 GB RAM\u003C\u002Fli>\u003Cli>Pricing reflects early RISC-V hardware\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>How to decide\u003C\u002Fh2>\u003Cp>Pick the K3 if you want the most convincing sign yet that RISC-V can run a modern Linux desktop with real responsiveness. It is the best fit for developers, distro testers, and hardware watchers who care more about capability than bargain pricing.\u003C\u002Fp>\u003Cp>If you want a cheap board for tinkering, the Raspberry Pi still wins on price. If you want a compact RISC-V machine with real storage, display output, and serious I\u002FO, the K3 Pico-ITX or NUC-style system is the more interesting buy.\u003C\u002Fp>","4 ways SpacemiT’s K3 mini
