ROCK 3A

Radxa team has just announced their latest SBC named ROCK 3 powered with a brand Rockchip RK3568 chip. The new hardware also includes a few improvements, such as DDR4 memory and QC/PD power support. In Comparison to the previous Rockchip RK3399, its new CPU can reach up to 2GHZ, plus the GPU is faster than the ARM Mali-T860 MP4, capable of reaching up to a respectful higher frequency of 800-950 MHz.

ROCK 3A is simply an improved version of ROCK Pi 4 with some performance enhancements as well as additional new interfaces.

    Yet another Rpi competitor that looks so good on paper. Yet 7 months later we still have hacked OS’s that only partially work. I am not criticizing the many volunteers that work on these projects, but I am criticizing the companies who offer glorious (potentially) hardware, that needs others working for little to nothing to hack together a workable set of instructions to try to get the board to live up to its potential. I have one of these boards, and some of the connectors are shoddy and fragile to say the least. To verify that all the hardware functions as it should is impossable unless your knowledge level is that of a software engineer, or you wish to wait for a bonified offering from a OS supplier like Manjaro or Ubuntu to write a distro for this board. Would I buy one again, in a word no.
