Here are some of the first pictures of a socket AM4 motherboard by GIGABYTE. Positioned as an entry-mainstream offering by the company to launch with AMD's 7th generation A-series "Bristol Ridge" APUs, while being ready for upcoming "ZEN" based CPUs and APUs, this board appears to be based on AMD B350 chipset, the company's mid-tier socket AM4 chipset alongside the entry-level A320 and enthusiast-segment X370. This board appears to feature a rectangular CPU cooler retention-module like older AMD sockets. Could the "square" bolt-type RM we spotted on OEM boards, as well as AMD's own platform demonstrator board not make it to the DIY segment?

This unnamed (label not clearly pictured) motherboard is built in the micro-ATX form-factor, drawing power from 24-pin ATX and 8-pin EPS power connectors. It uses a 7-phase CPU VRM. AMD appears to have introduced new voltage domains with AM4, probably because these are full-fledged SoCs, with core-logic completely integrated. The board features four DDR4 DIMM slots, and PCI-Express gen 3.0 slots. The B350 chipset wires to the SoC over PCI-Express gen 3.0, and puts out additional downstream general-purpose PCIe gen 3.0 lanes, besides additional SATA 6 Gb/s and USB 3.1 ports.
