Head-to-Head
RGB20 Pro vs X35S
RGB20 Pro vs X35S: a head-to-head comparison of specs, performance, screen, battery, and which one is the better buy for your retro library.
RGB20 Pro
PowKiddy · 10/10 · A+
The PowKiddy RGB20 Pro is the stronger package: the two devices share the same RockChip RK3566 and 1 GB of RAM and grade identically all the way to N64, Dreamcast and PSP, so the RGB20 Pro's advantages sit in the hardware around the chip. It pairs a sharper 3.2 inch 1024x768 display with a 5000 mAh battery, where the X35S offers a 3.5 inch 640x480 panel and a 3000 mAh cell. The price gap is only about ten dollars (roughly $70 against $60), which is cheap for the extra resolution and the much larger battery. Buy the X35S only if the smaller spend is the deciding factor and the sharper screen does not matter to your library.
