The PGS Portable aims to ship two competing versions. The lite version and the more souped up hardcore version. The hardcore version aims to ship with a 2560 X 1440 QHD Display, Windows 10, Intel Atom Quad-Core 2.4GHZ, Intel HD graphics, 8G RAM, 128G SSD, wireless n, bluetooth, usb 3, microHDMI, headphone jack, webcam and a DS-like second display. They claim the battery life should last up to 5 hours but I imagine that depends on the game and other factors. Compared to the GPD Win the PGS Portable is visually stunning and seems to be aiming directly at owners of existing Sony and Nintendo handhelds.
Like I said before, I imagine this space will heat up significantly as all the power we've come to love from our phones comes to PC gaming and I can't wait to see how it turns out.
