The GPD Win is a Windows10-Handheld with an x86-Processor, new revision 2, with the Z7850 processor.
Included in this package is also a carry case, an HDMI-Cable and four replacement rubber caps for the analog sticks.
Questions and Answers:
Q: What's the difference of Revision 1 and Revision 2?
A: Revision 2 has a few improvements. It features an improved DPad silicon mat and keyboard as well as a less shiny case (that doesn't collect fingerprints as easily). It also uses the Z8750-CPU, which is minimal faster than the older one (you probably can't notice it in real life).
The latest version (I call it Rev. 2.5) has a lid made of Aluminium.
Q: Is it possible to install a different OS (i.e. Linux)?
A: Maybe. The device has no locked bootloader, but there is no official support for anything else except Windows 10. Besides, similar Intel SoCs are known to have issues running Linux. So it might work, but we cannot promise anything.
Q: Is it possible to install a different Windows 10 version?
A: Yes. You can find the drivers for that here at the downloads.
Q: Can the memory or CPU be upgraded?
A: No, that's not possible. You can only increase the internal storage using a MicroSD-Card.
Q: Can the GPD Win play ALL Windows PC Games?
A: In theory, yes. However, RAM and Processor can cause issues. The processor is about as fast as a normal desktop PC from 2010. Many current Indie games and other not-processor-hungry games will work fine, but don't expect it to run the latest commercial games (like Witcher 3 or GTAV) in full speed!
