Both the PowKiddy RGB20SX and X35S launched in 2024 at $60, share the same RockChip RK3566 chip, run Linux, and top out around PSP emulation, so the choice comes down to form and feel rather than raw capability. The RGB20SX arrived in April with a vertical layout that has since proven popular; the X35S followed in August with its own take on the same vertical format. Buyers should compare grip ergonomics and screen specifics between the two before deciding.
