The mini-ITX board has fewer slots of course, and adds a USB 3.1 controller, but...well, did you notice this page's title? It seems that while everyone was talking about the transition of mini-ITX to performance platforms (2007), AMD was pushing DTX as a means to standardize the SFF–type gaming machine. That’s “Shuttle” form factor. Its main benefit over mini-ITX was a 9.6” front-to-back measurement, the same as a microATX motherboard, which meant that it had space for four DIMMs. Our benchmarks will show whether the missing memory channels are a real problem or a mere distraction.
