Radxa ROCK 5C review

The ROCK 5C is built around the Rockchip RK3588S2. It has four Cortex-A76 cores at up to 2.4GHz and four Cortex-A55 cores at up to 1.8GHz, with an Arm Mali-G610MC4 GPU and a 6 TOPS NPU. That suits multi-threaded work such as builds, containers and local services. Owners praise its multi-core performance and value.

RAM comes in 4GB, 8GB, 16GB and 32GB versions. The V1.1 board uses LPDDR4X and the V2.1 board uses LPDDR5, so check which revision you are buying. The 16GB and 32GB tiers give container-heavy setups plenty of headroom.

Radxa lists its own Debian and Android images, along with third-party systems. Notebookcheck says Android is only on the 5C. That gives you official images from the manufacturer as a starting point, with third-party systems as alternatives.

Because support comes through Radxa's images and those third-party systems, check that the image you want covers your workload before you commit to a specific project.

This is the board's main limitation. It has one eMMC connector and one microSD slot, with no SPI flash and no native M.2 slot. The one route to fast storage is a 1-lane PCIe 2.1 connection through an FPC connector.

Owners complain that storage is bottlenecked by microSD. If you stay on a card, that matches the complaint. If you use the PCIe connector for a drive, owners report that the drive stays powered and heats up when the board is off. That matters for anyone planning an always-plugged-in setup.

Networking is Gigabit Ethernet, with PoE possible through an optional HAT. Wireless is WiFi 6 and Bluetooth 5.4, with an external antenna connector. There is no 2.5GbE port, so wired throughput tops out at gigabit.

The 40-pin header follows the Raspberry Pi-style layout, with 3.3V logic and up to 27 GPIO. That helps if you already have wiring built around that pinout. Video outputs are one HDMI 2.1 port up to 8K and one MIPI DSI up to 2K.

The board runs from 5V over USB Type-C. Radxa recommends at least 10W, and 25W with full USB and PCIe load. No power supply is included. You need to buy a USB-C PD adapter of 30W or more separately, and owners list this as a complaint. Budget for that extra purchase.

With eight cores, a 6 TOPS NPU and up to 32GB of RAM, the ROCK 5C suits compute-heavy hobby projects, container hosts and edge experiments. With microSD, eMMC or an FPC-connected PCIe drive as the only storage options, it suits you better if you are comfortable adapting storage than if you want a plug-in NVMe drive. Owner feedback points the same way: strong value and multi-core performance, held back by storage, the missing power supply and PCIe power behaviour.
