The suffix “X” following the model number indicates the Roku device unit itself. Nowadays, this is the only indication of the suffix, with “R” (which indicates retail stores) additionally indicating the packaging for the Roku or its accessory. Ten years ago, the “X” suffix additionally indicated online stores, whereas retail stores were the only indication of the “R” suffix.
The list of suffixes and its indications can be determined on this topic here: https://community.roku.com/t5/Roku-Legacy-Products/Retail-Country-Accessory-and-Unit-Codes-of-Roku-D...

I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
