First images of AMD AM4 motherboards for Zen and Bristol Ridge processors have leaked out via a Korean tech site Bodnara. Leaked photos show two AM4 motherboards from Gigabyte, both featuring the mid-range AMD B350 chipset.
The AMD AM4 socket is designed to combine the company’s CPU and APU offerings under one roof. Meaning, the new AM4 boards will be compatible with everything from the just-launched Bristol Ridge APUs to the upcoming Zen-based Summit Ridge CPUs. The AM4 platform is powered by the Promontory chipset stack, and supports a variety of features, including DDR4 memory, PCIe Gen 3, M.2 connectivity, and much more.
There are four chipsets offered on the AM4 platform: the X370 for enthusiasts, the B350 for mainstream market, the A320 for the essential market, and finally the A300 for small form factor systems. The leak details motherboards from Gigabyte that come in an mATX form factor and house the mid-range AMD B350 chipset.
Gigabyte AM4 Motherboards Photos Leaked – DDR4 Memory Support, 7-phase CPU VRM & More
The first AM4 motherboard features four DDR4 DIMM slots, two PCIe 3.0 x16 expansion slots, four SATA3 6Gbps ports, and an NMVe M.2 interface. The board uses a 4+3 — 7-phase CPU VRM and draws power from 24-pin ATX and 8-pin EPS power connectors.
The on-board audio is powered by Realtek’s 8 channel ALC887 HD audio codec and is separated from the rest of the board that should help minimize interference. Moreover, Gigabyte has integrated this AM4 board with dual BIOS functionality to improve safety and offer more convenient flashing.
The I/O consists of two USB 2.0 ports, four USB 3.0 ports, two USB 3.1 Type-A ports, a PS2 combo port, D-Sub, DVI-D, HDMI and three audio jacks. There’s no integrated Wi-Fi but a built-in Realtek 8111G Gigabit Ethernet controller to handle LAN.
The second AM4 motherboard from Gigabyte carries the model number GA-B350M-D2, and features the same 7-phase power delivery design with an auxiliary 8-pin power connector. This one however features only two DDR4 DIMM slots rather than four on the other AM4 board. For expansion, we have a single PCIe 3.0 x16 slot and two PCIe 2.0 1x slots.
The on-board audio solution remains identical, along with the same network connectivity port. In terms of I/O, the board comes with two USB 2.0 ports, two USB 3.0 ports, one USB 3.1 Type-A port, a PS2 combo port, D-Sub, DVI-D and three audio jacks.
With AMD Bristol Ridge APUs rumored to launch in next month, we hope to see plenty of these AM4 motherboards soon.
