Unlike GPD's Win Max mini laptop, the OneGX1 from One-Netbook is a bit more compact since it does not integrate game controller buttons, but it may also prove a bit faster as it is supposed to integrate Intel's Tiger Lake CPUs. The design appears inspired by Dell's Alienware Area-51m, and this is also said to be the first mini laptop to offer 5G support.
