AMD X670E Chipset Architecture

AMD’s X670E chipset uses a high-end AM5 platform architecture. It is designed for Ryzen series CPUs with a dual-chiplet (“Promonotory 21”) design by supporting PCIe 5.0 for both NVMe and GPU slots. In addition, it uses a 4-lane PCIe 4.0 link to the CPU by allowing wide, overclockable I/O options. It supports Ryzen series processors, extensive USB 3.2/4.0 support, superior overclocking, and DDR5 memory capability.

Components

The AMD X670E chipset architecture can be built with different components like Dual-Chipset (Promontory 21 x2), CPU-to-Chipset Link, PCIe 5.0 Support, Memory Architecture, Storage (SATA/NVMe), USB Capabilities, Networking, and Overclocking.

Dual-Chipset (Promontory 21 x2)

The AMD X670E chipset architecture uses a dual-chiplet design with two “Promontory 21” (PROM21) silicon dies. These dies deliver I/O and high-end connectivity capabilities for the AM5 Socket platform. X670E motherboards use two PROM21 chipset dies connected in a daisy-chain configuration. The first chipset connects directly to the CPU through a PCIe 4.0 x4 link, while the second chipset connects to the first, expanding the available I/O lanes. Therefore, the Promontory 21 chip is a high-speed, versatile PCIe hub that allows AMD to balance I/O capabilities without designing various and different chipset dies, which is an efficient design approach for exclusive AM5 motherboards.

CPU-to-Chipset Link

This is a high-speed connection that uses 4 PCIe 4.0 lanes to connect the Ryzen series CPUs to the PROM21 chipset. X670E chipset uses a dual-chiplet design, which provides additional PCIe 4.0/3.0 lanes & SATA ports.

PCIe 5.0 Support

The AMD X670E chipset provides the maximum range of PCIe 5.0 motherboard support within the AM5 platform. It mandates Gen5 lanes for the main graphics slot (x16) & minimum one M.2 NVMe SSD slot. Therefore, PCIe 5.0 provides up to 32 GB/s per direction for x16 links, doubling the bandwidth of PCIe 4.0. When the chipset architecture utilizes PCIe 4.0 for the link between the CPU & the chipset itself, then the main PCIe slots for components use the complete speed of 5.0 by providing twice the bandwidth of PCIe 4.0.
