Ryzen is the codename of AMD’s next-gen processors that were released in the first quarter of 2017. AMD released motherboard socket AM4 for the Ryzen CPUs, and AM4 motherboards were released at the same time as the processors.
Summit Ridge is the codename of the first Ryzen based high-end CPUs. The first Ryzen 7 chips to be released are the 1800X, 1700X, and 1700, all of which feature eight cores.
Read on as we review and compare some of the best socket AM4 motherboards for Ryzen 7 processors.
Before you read the reviews, here is a quick comparison of the best AM4 motherboards.

Support for the Latest Technologies
AM4 motherboards bring AMD back into the present, never mind the future, with features that Intel socket motherboards have supported for a few years now. They are the first AMD motherboards to support dual channel DDR4 memory, with a total of four DDR4 memory modules and speeds up to 3200MHz. There is also native support for PCIe 3.0 and USB 3.0 + 3.1.
AM4 is the first socket from AMD that provides compatibility between high end CPUs and lower end APUs, replacing previous AM and FM sockets by merging them into a single socket.
Socket AM4 ships with four chipsets, the enthusiast X370, the mainstream B350, and the entry-level A320. The other chipset includes X/B/A300 configurations for small form factors.
AM4 is a PGA socket with ZIF that measures 40 x 40mm, which is the same area as socket AM3+. It has 1,331 pins, which is a major increase over AM3+ and its 942 pins, which significantly more than Intel socket LGA 1151. The only downside to the increased number of pins is that the mounting holes have been housed differently, which means coolers that were compatible with AM2, AM2+, AM3, and AM3+ sockets will no longer fit on the socket AM4 motherboards. However some manufacturers, including Noctua, have announced they will be offering a free upgrade to its customers so they can continue using their existing coolers on AM4 motherboards.
