According to a report from VideoCardz, AMD is preparing to launch a new range of EPYC branded server processors in the Socket AM5 package. These processors are designed to cater to two specific customer segments - small business servers and data-centers that offer small-size dedicated servers, which previously had to rely on Ryzen chips. Intel, on the other hand, currently has the Xeon E-2400 series "Raptor Lake-E" processors in the Socket LGA1700 package targeting similar customers.

The EPYC 4004 series will be based on the same "Raphael" package as the Ryzen 7000 series, offering an upgrade from the Ryzen PRO 7000 series. The key difference between the Ryzen PRO 7000 and EPYC 4004 series lies in their target markets, with the former focusing on commercial desktops. AMD's support and warranty for server processors also set the EPYC 4004 series apart.

The EPYC 4004 series CPUs in the "Raphael" package will feature core counts ranging from 6 to 16, based on the "Zen 4" microarchitecture. The memory controllers in the I/O die are expected to be reconfigured to support server memory densities and ECC support, similar to the Ryzen PRO 7000 series. There are discussions about potential variants with 3D V-cache, with uncertainty regarding whether the 12-core and 16-core variants will follow the model of the 7900X3D and 7950X3D.

Socket AM5 motherboards from companies like Advantech are already available, offering server-grade features and relevant I/O for the EPYC 4004 series. This existing ecosystem provides upgrade potential for future generations of EPYC processors.
