AMD has just introduced the 5th Gen AMD EPYC Embedded 9005 Series “Zen 5” processors designed for embedded systems with a focus on longevity (7 years), reliability, and system resiliency, and targeting networking, storage, and industrial edge systems with support for up to 6TB of DDR5 memory, up to 160 PCIe Gen5 lanes with CXL 2.0.
The EPYC Embedded 9005 Series processors are offered with 8 to 192 cores in a single socket and deliver up to a 1.3x faster networking process and 1.6x faster storage. The company also claims a 1.3x increase in socket throughput and 1.3x better performance/Watts compared to the competition thanks to the new Zen 5c architecture.
AMD EPYC Embedded 9005 highlights:
- CPU sub-system
- AMD EPYC Embedded 9745 to 9965 – Zen 5c architecture up to 12x core complex dies (CCDs), 192x cores, 384x threads
- AMD EPYC Embedded 9015 to 9655 – Zen5 architecture up to 16x core complex dies (CCDs), 128x cores, 256x threads
- Supports classic (4nm) and dense (3nm) cores
- Gen 3 AMD Infinity FabricTM architecture with up to 32 Gbps die-to-die bandwidth
- 1 MB L2 cache per core, up to 32 MB L3 per CCD
- Memory

- 12-channel DDR5 with ECC up to 6000 MT/s
- Option for 2, 4, 6, 8, 10, and 12-channel memory interleaving
- Up to two DIMMs per channel capacity of 9 TB/socket (384 GB 3DS RDIMMs)
- I/O:
- 160x lanes (2P) or 128x (1P) lanes of PCIe Gen5
- Speeds up to 32 Gbps with bifurcation supported down to x1
- PCIe link encryption and PCIe Hotplug port reconfiguration
- CXL 2.0, four x16 capable “P” links; Type 3, Type 1 and 2
- Up to 32x I/O lanes for SATA
- SDCI (Smart Data Cache Injection)
- 4x USB 3.2 Gen2x1 ports, including support for legacy USB speeds
- RAS (Reliability, Availability, and Serviceability)
- Advanced Memory Device Correction
- Dynamic PPR (Post Package Repair) to repair faulty DIMMs
- BMC MCA crash-dump
- Out-of-band error polling over APML
- Additional functionality
- NTB (Non-Transparent Bridging)
- DRAM flush
- Non-Volatile CXL Memory Module (NV-CMM)
- Dual SPI to load a secure and proprietary bootloader to authenticate the platform, ensuring a trusted execution environment.
- Security
- Hardware root-of-trust
- Secure I/O (SEV-TIO)
- SME, SEV-ES, SEV-SNP, SMKE
- SP5 socket form factor
17 SKUs are available with a TDP from 125W up to 500W. AMD has some interesting “embedded” parts that look more like something you’d find in a datacenter…
The company explains that NTB (Non-Transparent Bridging) increases availability in fault tolerant multi-host configurations, enhances system redundancy and failover capabilities for networking and storage systems by enabling data exchange between two CPUs in active-active configurations via PCI Express to allow continued operation in case of a failure.
Software support includes a Yocto-based framework to create custom Linux distributions tailored for the customer’s system, as well as SPDK (Storage Performance Development Kit) and DPDK (Data Plane Development Kit) specific to network and storage workloads.
The AMD EPYC Embedded 9005 Series will be used by various ODMs and OEMs, including Cisco and IBM, with notably the IBM Storage Scale System 6000 designed for enterprise AI workloads. Additional information may be found on the product page and the press release.
