The AM4 socket uses a square physical package measuring roughly . Unlike Intel’s LGA (Land Grid Array) sockets, which place pins on the motherboard, AM4 follows a PGA (Pin Grid Array) design where the pins are located on the underside of the processor. Key Specifications Pin Count: 1,331 pins in a 1.14mm pitch grid. Memory Architecture: Dual-channel DDR4.
Large clusters of pins that provide high-current voltage to the CPU cores and SoC. VDDCR_CPU , VDDCR_SOC , VSS (Ground) am4 pin layout
