It provides a visual representation of how modern "System on a Chip" (SoC) designs prioritize communication, showing how much physical space is dedicated to memory and PCIe compared to raw power. Technical Layout
is a community-sourced spreadsheet file that provides a comprehensive mapping of the 1,331 pins found on AMD's AM4 CPU socket. It serves as a vital technical reference for hardware enthusiasts, overclockers, and engineers looking to understand the physical and electrical layout of Ryzen processors. Purpose and Origin AM4_Pinout.ods
These pins supply power to different parts of the chip, such as the CPU cores (VCORE), the integrated graphics (SOC), and the memory controller. It provides a visual representation of how modern
A large block of pins dedicated to communicating with RAM. These are sensitive to physical damage; a single bent pin here can "kill" a memory channel. Purpose and Origin These pins supply power to
The spreadsheet categorizes the 1,331 pins into several functional groups, typically color-coded for clarity:
Pins that handle high-speed data for GPUs and NVMe SSDs.
