‘Zeppelin’: An SoC for multichip architectures

Codenamed “Zeppelin”, AMD's next-generation System-on-a-Chip (SoC) was designed for use in multiple products and packages in multiple markets, including server, mainstream PC desktop, and high-end desktop. Utilizing GLOBALFOUNDRIES' 14nm LPP FinFET process technology, the “Zeppelin” SoC has over 4.8B transistors. It contains high-performance AMD x86 cores codenamed “Zen” [1][2], caches, memory controllers, PCIe®, SATA, and other IO controllers, and integrated x86 southbridge chipset capabilities. All these functions are connected on the SoC and between multichip packages and multi-socket systems by AMD Infinity Fabric.
