Here's one of the first photos of a motherboard for AMD's upcoming Ryzen desktop processor. TechPowerUp got its hands on a picture of the bare PCB of the Gigabyte AX370-Gaming, an upcoming Socket AM4 motherboard that is expected to be launched around February 2017.
This will be one of the new high-end ATX boards for AMD's first Zen architecture but it will also support the current-gen Bristol Ridge APUs. The latter share the Socket AM4 with Zen but they're kinda hard to find.
The board draws power from 24-pin ATX and 8-pin EPS power connectors, and conditions it for the CPU with a 7-phase VRM. The AM4 socket is wired to four DDR4 DIMM slots. Expansion slots include one PCI-Express 3.0 x16, a second gen 3.0 x16 slot that's electrical x4, and three other gen 3.0 x1 slots. Storage connectivity appears to include at least eight SATA 6 Gb/s ports, and one 32 Gb/s M.2 slot. 8-channel HD audio, gigabit Ethernet, USB 3.1 (including type-C) ports, appear to make for the rest of the connectivity. GIGABYTE's signature Dual-UEFI is featured.
