Compact computing systems have gained significant market share over the last decade. Improvements in the performance per watt metric of processors have enabled the replacement of bulky desktop PCs by ultra-compact form-factor (UCFF) machines with a 4 in. x 4 in. footprint. Motivated by IoT applications at the edge, some companies started creating x86 systems in sub-4x4 form-factors using Intels Apollo Lake processors. ECS was one of the first mainstream vendors to pay attention to this segment with their LIVA Q Series using Intels Atom series and AMDs first-generation Ryzen Embedded SoCs. With the introduction of more power-efficient platforms, Asian manufacturers such as ACEMAGIC, GMKtec, and MinisForum have also entered this micro-PC market with a wider range of processor choices.
