Radxa's new Q8B single-board computer is turning heads, and Jeff Geerling's early coverage confirms what the specs suggest: roughly double the CPU performance of a Raspberry Pi 5, with meaningfully better expansion.

The board uses the Rockchip RK3588 — an octa-core chip with four A76 big cores and four A55 efficiency cores. Crucially for homelabbers, it offers more PCIe lanes and native NVMe support, which makes it a genuinely viable option for a compact NAS, Docker host, or Kubernetes node without the bottlenecks you hit on a Pi 5's single PCIe 2.0 lane.

Why homelabbers should care

If you've been stretching a Pi 5 to run multiple containers or transcode media, the Q8B looks like the logical next step without jumping to a full x86 mini PC. More RAM options, better I/O, and that RK3588 SoC has strong mainline Linux support at this point.

Honest caveats

Software maturity still lags behind the Pi ecosystem. You won't get the same depth of community tutorials, and some images may need tweaking. Driver support for the Mali GPU is improving but isn't seamless. And pricing — while competitive — tends to creep up once you add a case, cooler, and storage. Check current availability carefully; Radxa boards can be patchy in UK stock.

It's also worth noting that the Pi 5 remains hard to beat for projects where community support and plug-and-play software matter more than raw speed.

What to do

If you're considering one for a compact NAS or container host, you'll want an NVMe drive to take advantage of that faster storage bus. Our M.2 NVMe SSD Enclosure – USB-C 10Gbps with Magnetic Closure is handy for cloning or migrating drives during setup, and a 240W USB-C Fast-Charging & Data Cable – Braided, LED Indicator will keep your bench tidy if the board supports USB-C power delivery.

For the board itself, check Radxa Q8B for current UK pricing and stock. Worth bookmarking even if you're not buying today — this is where ARM homelabs are heading.
