The Anbernic Win600 is a small compact Windows handheld, the 1280x720 resolution works really well with the screen size.
Speed-wise, the small AMD processor is about the same as the latest version of the GPD Win 2 - both have a passmark of about 2900. GPU processing power is also similar, though the Radeon drivers (which the Win600 uses) are generally more compatible with games than those from Intel.
This is obviously not enough for the latest AAA titles, but if you like to run some older PC games, indie titles or emulators, this little guy can do it.
Windows 10 Home is included, SteamOS can be installed without problems and Batocera Linux (ideal for emulation) can be booted directly from an SD card.
Fortunately, both the RAM and the SSD storage can be easily replaced and upgraded.
The USB-C port also supports HDMI and Displayport, so you can connect the handheld to a TV with a corresponding adapter.
