AMD’s AM4 socket has been spotted, with 40% more pin count than AM3+ socket

AMD’s AM4 socket has been spotted, unveiling a total pin count of 1331 for AMD’s Summit Ridge CPUs, which is an increase of over 40% increase compared to AMD’s older AM3+ socket, which has a total of 942 pins. Despite using the PGA (Pin Grid Array) design, AMD manages to put more pins on AM4 socket than Intel LGA 1051 socket, which is an impressive achievement for AMD.

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.

Currently, AMD’s AM4 socket is said to have support for 3200MHz dual channel DDR4 memory and up to 24 PCIe lanes depending on the motherboard’s chipset. As of now, the first AM4 motherboards are expected to show up with AMD’s 7th generation of Bristol Ridge APUs, though AMD’s Zen-powered Summit Ridge CPUs are supposed to launch in early 2017.
