The successor to the GPD Win 2 is a handheld gaming device with a similar design to the Aya Neo or Nintendo Switch, running Windows 10 Home Edition.
The Core i5 1135G7 is fast enough to handle emulation up to (and including) PS3, Nintendo Switch or Nintendo 3DS (of course, not all games will run in fullspeed).
It's also capable of running most modern PC titles (playable, not as slideshows) like GTA V, Witcher 3 or similar.
While the cheaper version of the GPD Win 3 is not as powerful as the more expensive one, it should still be fast enough for most gamers out there.
What makes it stand out is keyboard hidden behind the LCD: You can slide the screen up and reveal a keyboard. So if a game needs some quick keyboard input, that's not a problem.
With the (optionally) available docking station, you can basically change it into a fully fledged desktop PC, with resolutions up to 4k on an external monitor.
It's also possible to connect an external graphics card to speed things up!
Included in the internal M.2 2280 slot is a 1TB NVMe storage card - but you can upgrade it anytime.
The battery lasts between 3 hours (heavy use) to 14 hours (light use).
Included in the package is the GPD Win 3 as well as a charger (EU version).
