Features of AMD EPYC Embedded 9005 Series Processor

The fifth generation "Zen" architecture breaks through performance and efficiency barriers, enhancing the resilience of networks, storage, and industrial systems
The AMD EPYC (Xiaolong) embedded 9005 series processor brings server level performance to embedded applications. They are based on the Zen 5 architecture and can provide excellent core density, energy efficiency, and computational throughput, providing higher levels of performance for network, security, storage, and industrial solutions.
The AMD EPYC embedded 9005 series processor can scale up to 192 cores and 160 PCIe Gen5 channels in a dual slot configuration, providing excellent I/O agility and workload flexibility. Advanced security and reliability features ensure critical task performance, and the planned delivery period is extended to up to 7 years, making it suitable for long lifecycle embedded deployments. These processors are fully compatible with the previous generation platform, providing a seamless upgrade path and offering OEM manufacturers scalable and energy-efficient solutions to meet the demanding requirements of embedded systems.
High performance, reliability, and optimized energy efficiency are crucial for network, storage, and industrial applications, and the EPYC embedded 9005 series processor provides the following features:
In terms of network
These processors provide efficient CPU core performance for packet forwarding and processing, offering high core density suitable for scalable balanced networks, thereby enhancing the performance of enterprise and edge routers, security devices, and firewalls.
For enterprises and cloud storage
This series provides powerful media connectivity across PCIe Gen5, SATA, and Compute Fast Link (CXL) 2.0, as well as features to protect data availability and retention during power outages.
In industrial applications
The EPYC embedded 9005 series processor is capable of real-time data processing with optimized power consumption, while its built-in security features enhance physical and virtual layer protection.
Enhanced features specifically designed for embedded requirements
The AMD EPYC Embedded 9005 Series processors provide embedded specific features to enhance platform lifespan and system resilience, including:
Non transparent bridging (NTB) can provide higher availability in fault-tolerant multi host configurations. NTB enables data exchange between two CPUs in a dual active (active/active) configuration via PCI Express (PCIe), enhancing system redundancy and failover capabilities for network and storage systems to allow for continued operation in the event of a failure.
The Dual Serial Peripheral Interface (SPI) function supports two off chip ROMs for secure boot. The first ROM contains the BIOS image, and the second ROM contains the client's proprietary boot loader to verify and load the BIOS image.
The Direct Memory Access function can minimize CPU involvement in data transfer, thereby improving system efficiency and performance. By delegating data transfer to the DMA engine, the CPU core can better support critical computing tasks related to applications.
DRAM Flush to NVMe: In the event of a power outage, data will be flushed from DRAM to NVMe SSD to ensure critical data is preserved.
The Yocto Project framework supports customizable Linux distribution builds, empowering customers to build lightweight, optimized, and space efficient operating systems, making it ideal for embedded systems.
Excellent performance and scalability
The AMD EPYC embedded 9005 series processor can provide support for computationally intensive embedded systems, with a single slot core count ranging from 8 to 192. The leading core density makes these devices highly suitable for network, security firewall, storage, and industrial control applications. With up to 160 PCIe Gen5 channels 1 and CXL 2.0, they can achieve high-speed data transfer for networks and storage. DDR5-6000 memory and efficient power management can improve workload responsiveness.
Built in security
The EPYC Embedded 9005 series supports all the confidential computing functions of our previous generation products, including secure memory encryption SME, secure encryption virtualization SEV, SEV encryption status, SEV secure nested pages, and hardware verification boot. The fifth generation product has added AMD Trusted I/O. This feature builds a framework for protecting virtualized I/O paths. It supports the PCI-SIG TDISP standard for mutual authentication of virtual machines (VMs) and devices, and then establishes encrypted connections. The framework provided by AMD Trusted I/O ensures mutual trust and security of data during transmission.
Enterprise level reliability, availability, and serviceability (RAS)
The AMD EPYC embedded 9005 series processors provide seamless performance 24/7 for storage, networking, and security workloads. The main reliability, availability, and serviceability functions include:
DRAM ECC supporting Advanced Memory Device Correction: detects and corrects individual DRAM device failures, extending system uptime.
APML based Crash Dump and Machine Validation Architecture (MCA): allows processors to report out of band fatal and runtime errors to the platform without stopping the x86 core.
DRAM Runtime Package After Repair (PPR): Real time reconfiguration of faulty DIMM rows to maintain reliability without the need for system restart.
Extended service life
In order to meet the longer product lifecycle and operational requirements of the embedded market, AMD EPYC Embedded 9005 Series CPUs provide extended 7-year product manufacturing support to help system designers ensure long-term product availability and reduce redesign and certification work. In addition, AMD plans to extend the design lifespan of the current AMD EPYC embedded 9005 series CPUs from 5 years to 7 years for mass-produced SKUs to ensure the long-term product stability of embedded systems. These extended design life operational goals are crucial for embedded systems that operate critical task applications under harsh conditions, minimizing unplanned downtime, maintenance, and costly system replacements.
