Rock Pi 4 Model C+ released with HDMI 2.0 ports, LPDDR4 RAM and M.2 SSD support
The Rock Pi 4 Model C+ is another single-board computer (SBC) from Radxa inspired by the Raspberry Pi. Incidentally, CNX Software notes that the SBC is the first in the Rock Pi 4 family to use the Rockchip RK3399-T, a downclocked version of the Rockchip RK3399. Specifically, the RK3399-T delivers a 1.5 GHz peak clock speed by default across its two ARM Cortex-A72 CPU cores.
However, the Cortex-A72 cores are overclockable to 2.0 GHz. Likewise, the SoC's four Cortex-A53 cores ship with a 1.4 GHz peak clock speed, they are also overclockable but only to 1.6 GHz. Incidentally, the Rockchip RK3399-T features a Mali-T864 CPU too, along with a VPU that can decode 4K H.264/H.265/VP9 videos and hardware encode H.264 content at 1080p.
Elsewhere, the Rock Pi 4 Model C+ has 4 GB of LPDDR4 RAM, dual micro HDMI 2.0 ports, a 40-pin expansion header and numerous storage options. As Radxa's marketing images show, the SBC has an eMMC socket, a microSD card reader and an M.2 2230 connector for NVMe SSDs. Please note that the latter supports up to PCIe 2.0 x4, while SPI flash can be mounted for booting from a network or an NVMe drive. Out of the box, the Rock Pi 4 Model C+ supports up to Android 11, Debian and Ubuntu Linux, among other operating systems.
Currently, Radxa offers the SBC through ALLNET China and ameriDroid from US$59.99 and US$64.95, respectively. While ameriDroid only stocks one SKU, ALLNET China also offers the Rock Pi 4 Model C+ with a small heatsink and fan for US$63.98. For reference, ameriDroid states that the Rock Pi 4 Model C+ is only available to pre-order, whereas ALLNET China suggests that it has stock of both SKUs.
