Epyc 4004 from US$149: AMD Ryzen processors with ECC RAM for small servers
The five new Epyc 4004s for single-socket servers are similar to the Ryzen 7000 desktop CPUs. They have 4 to 16 cores and officially support DDR5 RAM with ECC.

AMD is launching a new series of server processors. The initial five Epyc 4004 models with their four to sixteen CPU cores are positioned below the 8004 and 9004 families and are intended for servers with only one CPU version. In the case of the 65-watt four-core Epyc 4124P, they are available from 149 US dollars (all prices plus tax). The 16-core, most expensive Epyc 4004 CPU costs 699 US dollars, whether as a normal 4564P with 170 watts Thermal Design Power (TDP) or as a 4584PX with 3D-V cache, 120 watts and slightly lower clock rates.
The Epyc 4004s use the AM5 platform and are also based on the technology of the Ryzen 7000 desktop series, but are officially approved for up to 192 GB of DDR5 RAM with ECC memory protection. The CPUs are also validated for common server operating systems, for use with baseboard management controllers (BMC) for remote access and for (software) RAIDXPert2. As with the Ryzen 7000, the memory speed depends on the number of memory modules: With only two UDIMMs of 64 GB each, up to DDR5-5200 are allowed, with four memory bars only DDR5-3600.

The other features are also identical to the desktop platform: integrated graphics including modern video acceleration as well as HDMI and display port output if you want to maintain the server locally, plus up to 20 Gbps fast USB-C and 28 PCI Express 5.0 lanes.

Standardized technology for Windows Server
According to AMD, desktop Ryzen technology has been running in servers since 2019 and began with an ODM (Original Design Manufacturer) development for an EMEA customer in the field of dedicated hosting. This market has grown significantly since then, but requires standardized technology and some server features such as BMC, software RAID and validation for operating systems. AMD is now responding to this with the Epyc 4004 series, and at the same time wants to appeal to smaller companies for whom low costs are a factor. According to AMD, Windows Server is quite common in this market segment and only allows up to 16 cores in its standard license, which fits in well with the AM5 offering.

According to AMD, the Epyc 4584PX is up to 70 percent faster than Intel's eight-core Xeon E-2488 and offers a 50 percent better price-performance ratio. The Epyc 4344P, which also has eight cores, offers lower costs.
