Summit Ridge (SR) is the name of the core for AMD's high-end desktop (HEDT) microprocessor line based on the Zen microarchitecture. Summit Ridge processors are fabricated on GlobalFoundries 14 nm process.

Overview

Summit Ridge are actually a complete system on a chip with both the northbridge and southbridge on-die. Summit Ridge chips offer 16 PCIe lanes (generally for the GPU) along with an NVMe controller and an additional 4 PCIe lanes for I/O along with SATA and USB 3.0 links. However, AMD sells those chips along with the Socket AM4 chipset which provides support for additional resources (i.e., more PCIe lanes and USB ports).
