AMD has expanded its product lineup by introducing the EPYC 4004 server processors, which for the first time, utilize the consumer-oriented socket AM5, shared with the Ryzen 7000 desktop CPUs. These new server processors, based on the Zen 4 architecture, come equipped with up to 16 cores and 32 threads, mirroring the core and thread counts of the Ryzen 7000 series. The EPYC 4004 chips support two DDR5 memory channels and are distinctive for their official support for ECC (Error Correcting Code) memory, accommodating up to 192GB of RAM. Key features include up to 28 PCIe 5.0 lanes and an integrated RDNA 2 GPU, specifications that align closely with the Ryzen 7000 series. However, unlike traditional EPYC processors, the 4004 series does not support configurations with multiple sockets. While the hardware specifications are similar to the Ryzen 7000 models, the EPYC 4004 processors are tailored for enterprise applications with added support for server-specific operating systems, software RAID storage, and server motherboards equipped with BMC (Baseboard Management Controller) chips for remote management. This positioning allows AMD to cater to a broader range of applications by merging consumer and enterprise-grade features.

The new EPYC 4004 processors are compatible with the Socket AM5 package and feature up to 16 "Zen 4" CPU cores. They are equipped with a 2-channel DDR5 memory interface and a 28-lane PCIe Gen 5 I/O. These processors are designed to serve small-business servers and dedicated web-server hosting, a segment traditionally targeted by Intel’s Xeon E-2400 series in the LGA1700 package. Key advantages of the EPYC 4004 series include support for Error-Correcting Code (ECC) memory, AMD Secure Processor, and comprehensive security features similar to those found in the Ryzen PRO 7000 series processors for commercial desktops. These features offer an enhanced support and warranty regime compared to typical client-segment processors.

The architecture of the EPYC 4004 series is fundamentally identical to the Ryzen 7000 "Raphael" processors but with added support for ECC memory. Each chip can include up to two 5 nm "Zen 4" Core Complex Dies (CCDs) with up to 8 cores each, alongside an I/O die that supports two DDR5 memory channels and 28 PCIe Gen 5 lanes. With the launch of the EPYC 4004 series, server motherboard vendors are also releasing Socket AM5 server boards designed for rackmount installation and equipped with features pertinent to server use.

The processor lineup includes eight models varying in core count and Thermal Design Power (TDP) settings:

  • The 16-core/32-thread EPYC 4564PX operates at a base frequency of 4.50 GHz, with boosts up to 5.70 GHz, and a 170 W TDP, priced at $699.
  • The EPYC 4584P also offers 16 cores and 32 threads but has a lower base frequency of 4.20 GHz and a 120 W TDP, available at the same $699 price point.
  • The 12-core/24-thread EPYC 4464P features a 3.70 GHz base frequency, 5.40 GHz boost, and a 65 W TDP, priced at $429.
  • The faster 12-core EPYC 4484PX has a 4.40 GHz base frequency and 5.60 GHz boost with a 120 W TDP, costing $599.
  • The 8-core/16-thread models include the EPYC 4364P and 4344P, priced at $399 and $329 respectively.
  • The EPYC 4244P, a 6-core/12-thread processor, and the 4-core/8-thread EPYC 4124P are priced at $229 and $149, respectively.
