Difference between Rock and Rock Pi

[Melab]

I’m seeing model names like ROCK 4C and Rock Pi 4. Is there a difference between Rock and Rock Pi?

Rock 4 is serie of SBCs based on RK3399 with few variants and some versions like 4C 4C+ or 4 SE. Each has some unique features and versions so they can be different, but specs are mostly similar.
Radxa decided to not use “Pi” in names so “Rock Pi 4” become “Rock 4” now, If You see “Pi” anywhere just don’t mind that.
