The very first set of motherboards from AMD's upcomingAM4platform for Zen, Bristol Ridge & Raven Ridge have been detailed & pictured. These new boards will be compatible with everything from upcoming high-end Summit Ridge 8 core CPUs to mid-range and entry-level desktop APUs. The new details & photos come via the Korean hardware tech site bodnara.

AMD AM4 Motherboards From Gigabyte Pictured & Detailed

AMD's new AM4 platform will feature three different chipsets for three tiers. The entry-level A320 chipset, mid-range B350chipset and high-end X370 chipset. The updated chipset brings M.2 connectivity, PCI-E gen 3, DDR4 memory and much more to AMD's desktop platform. Currently, only a select number of OEMs have started systems with AM4 motherboards & Bristol Ridge APUs inside. So this represents the first ever leak pertaining to channel boards that you'll be able to buy in retail stores or via e-tail soon enough.

We have two AM4 motherboards from Gigabyte to talk about here, both feature the mid-range B350 chipset and come in an M-ATX form-factor.

The first board features two PCIe 3.0 x16 expansion slots and an NMVe M.2 interface. In terms of I/O the board comes with 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. Which brings us neatly to the ob-board audio. Which is physically separated from the rest of the board to minimize interference. Powered by Realtek's 8 channel ALC887 high definition audio codec & high-end Japanese capacitors.

As is with most modern motherboards Gigabyte's AM4 board comes with dual BIOS functionality for more convenient flashing and added protection in case overclocking fails or unstable settings are saved. Above you can see the UEFI screen showing the frequency & voltage of installed DDR4 memory modules.

The second board Gigabyte's entry-level OEM GA-B350M-D2 model. It features a 4+3 -- 7-phase -- power delivery desgin and an auxiliary 8-pin motherboard power connector. Unlike the other AM4 Gigabyte motherboard this one actually comes with only two rather than four DDR4 dimms. Storage wise we have four SATA3 6Gbps ports, two USB 3.0 front panel headers and one USB 2.0 front panel header. In terms of expansion this board comes with only PCIe 3.0 x16 slot and two PCIe 2.0 1x slots.

The on-board audio solution is identical here, featuring an 8 channel Realtek ALC887 high definition audio codec with premium Japanese capacitors. Just like the other board there's no integrated wifi and LAN is handled by a Realtek 8111G Gigabit Ethernet controller. I/O consists of 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.

AMD Zen Press Release

From 7th Gen APUs to upcoming Zen-based “Summit Ridge” desktop processors, the future-ready AM4 platform features the newest I/O standards and an AMD commitment to support it into the future.

The initial “Zen” cores for “Summit Ridge”-powered desktops will utilize the AMD AM4 socket, a new unified socket infrastructure that is compatible with 7th Generation AMD A-Series desktop processors. With dedicated PCIe® lanes for cutting-edge USB, graphics, data and other I/O, the AMD AM4 platform will not steal lanes from other devices and components. This allows users to enjoy systems with improved responsiveness and the future looking technologies that the AM4 platform provides, resulting in a powerful, scalable and reliable computing solution for all their needs.
