The ASRock N3700-ITX is a Mini-ITX motherboard that comes with a Pentium N3700 “Braswell” quad-core CPU soldered on it. It has six USB 3.0 and four SATA-600 ports, but its highlights are actually its low power consumption, low cost, and, of course, its small size.
The Pentium N3700 is an SoC (System on a Chip), meaning it has the CPU, GPU, memory controller, and chipset in the same chip. Actually, Braswell CPUs are an evolution of the Bay Trail-D processor, manufactured under 14 nm process, and with a TDP of only 4W or 6W. Besides that, Braswell processors come with a “generation 8” GPU, more powerful that the Bay Trail-D video engine, and two SATA-600 ports (earlier generation processors come only with SATA-300 ports).

The Pentium N3700 is targeted to desktop computers, has four cores running at 1.6 GHz (maximum clock of 2.4 GHz), and has 2 MiB of L2 cache. The Braswell family has other three CPUs, the Celeron N3150 (four cores, 2.08 GHz turbo clock), Celeron N3050 (two cores, 2.16 GHz maximum clock), and Celeron N3000 (two cores, 2.08 GHz maximum clock). All the models have a TDP of 6 W, except for the Celeron N3000, which has a TDP of 4 W.
You can see the ASRock N3700-ITX motherboard in Figure 1. It uses the Mini-ITX form factor, measuring 6.7” x 6.7” (170 x 170 mm).
