Radxa ROCK 5C (Rockchip RK3588S 8-Core / 4-32GB LPDDR4 / Gigabit Ethernet with PoE / WiFi 6 + BT 5.4 / PCIe 2.1) Review
The Radxa ROCK 5C is a compact single-board computer built on the 8-core Rockchip RK3588S, with 4GB to 32GB LPDDR4 options, PoE-capable Gigabit Ethernet, WiFi 6, Bluetooth 5.4, and PCIe 2.1 expansion.
The ROCK 5C is Radxa's mid-tier RK3588S board, using the same core Rockchip silicon family as their higher-end ROCK 5B but in a more compact, slightly cost-reduced package. The RK3588S is genuinely one of the most powerful ARM SoCs available in the SBC space, an 8-core big.LITTLE design that outperforms a Raspberry Pi 5 on raw CPU throughput and includes a built-in NPU for AI workloads that the Pi doesn't have at all. RAM configurability up to 32GB is unusual for a board this size, most competing SBCs cap at 8GB or 16GB, making the ROCK 5C a legitimate option for lightweight server, NAS, or even local AI inference workloads that need more memory headroom than a typical Pi-class board offers.
RK3588S Performance Class
This SoC family sits meaningfully above Raspberry Pi 5's Broadcom chip in raw compute, at the cost of a less mature software ecosystem and less community documentation than the Pi enjoys. If your project needs the extra horsepower and you're comfortable with a steeper setup curve, the performance gap is real and worth the trade.
Comparison to Alternatives
Against our Raspberry Pi 5 (8GB) and ASUS Tinker Board 3N, the ROCK 5C offers a stronger CPU, PoE support, and up to 32GB RAM, at the cost of the Pi's much larger community and software ecosystem maturity. Against our Khadas VIM4 (also RK3588S-family), the two are close competitors, VIM4 focuses more on media/entertainment use cases while the ROCK 5C's PoE and RAM ceiling lean it toward server/networking projects.

Expert rating8 / 10
Serious ARM compute and up to 32GB of RAM, if you can handle a thinner software ecosystem.
Best for
- Lightweight NAS, server, or local AI inference projects needing more RAM than a typical SBC offers.
- PoE-powered deployments where a single Ethernet cable for power and data simplifies installation.
Not for
- Beginners wanting the largest support community and simplest setup, Raspberry Pi remains the easier starting point.
- Buyers needing x86 software compatibility, this is ARM-based like all boards in this class.
