Radxa CM4: Affordable compute module with octa-core ARM CPU now available for purchase

Radxa recently detailed its latest offering in the system-on modules category, dubbed the CM4. As the name suggests, this affordable compute module is expected to sit right between the CM3 and CM5 compute modules, offering a decent set of features. The company has now revealed the pricing details as well, with the CM4 now starting at $70.

The primary difference between the CM5 compute module and the CM4 is the performance of the SoC, among other things. The CM4 is powered by the Rockchip RK3576 SoC, sporting an octa-core setup with four Cortex A72 and four Cortex A53 cores, along with a Mali G52 MC3 iGPU. The CM5 (currently $107 on Amazon), on the other hand, boasts the noticeably more powerful and pricier RK3588 SoC with Cortex A76 and Cortex A55 cores, as well as the Mali G610 MP4 iGPU.

The Radxa CM4 compute module, as mentioned, starts at $70 for the base variant with 32 GB of eMMC storage and 4 GB of LPDDR4X RAM. A variant with 8 GB of memory and twice the storage is also available, priced at $115. By attaching the CM4 I/O board, a multitude of ports can be achieved. The CM4 compute module is also compatible with third party boards, such as those from Raspberry Pi and WaveShare. Other key details of the CM4 are as follows:

• 4-lane or 2x2-lane MIPI CSI (video input)
• Dual SATA 3.1, single-lane PCIe Gen2
• Gigabit Ethernet (physical layer)
• OpenGL ES 1.1 to 3.2, Vulkan 1.2, OpenCL 2.1
• 4-lane MIPI DSI, HDMI (4K120), DP (4K120), 4-lane eDP
• Triple 100-pin B2B connectors
