ASRock Industrial is one of the few vendors with a lineup of ultra-compact form-factor (UCFF) computing systems based on the latest Intel and AMD platforms. Their lineup of NUC clones - the NUC BOX series with Intel, and the 4X4 BOX series with AMD - has enjoyed significant market success, mainly due to their commitment to leading edge processors. The company introduced the 4X4 BOX-7000 series UCFF PCs based on AMDs Rembrandt-R SoCs in early February, and sent across their flagship SKU - the 4X4 BOX-7735U/D5 - to be put through our rigorous evaluation routine.
