Its not a thinkpad. Its a small UMPC oriented towards games. It features an Intel Atom X7 Z8700, 4 GB RAM and 64 GB eMMC storage. The display is 5.5" multitouch with 1280x720.
Processorwise its around the same speed as the C2D T61 era TPs. Batterywise it should go around 10h, when not playing games.
It features USB type C for charging, miniHDMI, MicroSDXC (supports 256 GB cards), USB 3.0 and a headphones jack (3.5mm)
The T61F, the "small" TP8, and the tiny GPD.
