AMD introduced its EPYC 4004-series processors aimed at entry-level single socket servers designed for dedicated hosting and small businesses. The new EPYC 4004-series CPUs feature up to 16 cores and use AM5 packaging, providing a cost-effective platform that supports essential enterprise-grade capabilities.
AMD's EPYC 4004 processors are essentially Ryzen 7000-series CPUs with four, six, eight, 12 or 16 cores, up to 5.70 GHz boost clocks, up to 64 MB L3 cache, and up to 28 PCIe Gen5 lanes. The EPYC chips support up to 192 GB of DDR5-5200 memory with ECC. The platform features RAIDXpert2 for servers, AMD secure processor enclave, and transparent memory encryption (TSME). The EPYC 4004 lineup includes eight models with TDPs of 65W–170W.

AMD will have six EPYC 4004P-series processors ranging from the 4-core 4124P up to the 16-core 4564P. Other than support for ECC memory and the server-grade functionality, these are effectively the same as the Ryzen 7000-series CPUs. In addition, there are two EPYC 4004PX-class processors, the 4584PX and 4484PX, both boasting 128MB of combined L3 cache. These are the EPYC equivalents of the Ryzen 9 7950X3D and Ryzen 9 7900X3D CPUs that have an extra stack of cache over one of the CCDs.
AMD positions its EPYC 4004-series CPUs for a wide range of applications, including general-purpose small business servers, branch servers, backup and storage servers, dedicated applications servers (e.g., for Adobe Premier Pro, compilation machines), cloud gaming machines, and e-commerce workloads. Technically, with EPYC 4004-series processors, AMD can address almost any use case where high processing performance and extended availability are required.
Systems based on the EPYC 4004-series will support RAID, BMC, and server-grade OSes. Speaking of operating systems, since Microsoft's Windows Server 2022 Datacenter and Standard Edition OSes support up to 16 core CPUs in the base price, EPYC 4004 will be an optimal choice for these platforms.

"Historically, many small to medium businesses have had to compromise on their IT solutions by using hardware that does not fully meet their needs," said John Morris, corporate vice president, Enterprise and HPC Business Group, AMD. "Based on the same technologies that power the most demanding data centers in the world, the AMD EPYC 4004-series processors are offered at an optimized acquisition cost for customers in small and medium-sized businesses seeking to drive better business outcomes."
AMD says that EPYC 4004-based machines will be shortly available from Altos (an Acer company), ASRock Rack, Gigabyte, MSI, Supermicro, and Tyan, with more OEMs coming later. In addition, dedicated hosting providers OVHcloud and Ionos will also make EPYC 4004-based servers available to their clients. More providers are qualifying AMD's new platform with planned availability in 2024.

Wouldn't it be nice if ECC was standard (even if memory prices have to be jacked up ~15%) and not a confusing enterprise feature? No, not the DDR5 pseudo-ECC.
Other than that, I guess these are the enterprise features:
The platform features RAIDXpert2 for servers, AMD secure processor enclave, and transparent memory encryption (TSME).
Pricing looks very reasonable compared to the Zen 4 desktop lineup, for carrying the Epyc name. EPYC 4124P looks like it's based on an APU die with half the L3 cache.
One odd thing I noticed is that both the top two SKUs cost the same: EPYC 4564P and EPYC 4584PX costing $699 respectively !
One is the 3D V-Cache variant with 128MB cache, and the other one is obviously the vanilla SKU.
That's amusing. Some (many?) customers will definitely prefer the vanilla one with higher clocks, and may have no applications at all that benefit from 3D V-Cache. So AMD might as well charge the same and see if they can get away with it.
Too bad AMD didn't take the opportunity to launch a dual cache model (192 MB total L3).

There's but one, incredibly important question:
Can we OC 'em?
I don't know, but who needs it? These are clocked just as high as the identical Ryzen chips out of the box, which is unusually high for Epyc, and hitting up to 5.7 GHz which is still crazy to think about.
This does mean that, by EPYC server standards, the 4004 series is not particularly energy efficient. This is a lineup that is intended to be cost-effective first and foremost. Instead, energy efficiency remains the domain of the EPYC 8004, with its modestly-clocked many-core Zen4c designs.

Because they are the same ryzen chips, there is no way AMD paid for the same validation as for actual epyc but then sells them so cheaply.
They just added the I/O ,ecc mem, and whatnot to a normal ryzen package.

Doing what you say is a great way to kill the Epyc brand-name. From AMDs PDF about the release "By choosing the established EPYC brand for enterprises, you can be confident in using the EPYC 4004 Series as the foundation for your
growing business, hosting facility, or server appliance development. You can choose from a variety of solutions from key system vendors
with a multi-year CPU lifecycle support from AMD. We engage with our partners with server design and BMC validation, software RAID,
and chipset support. We’ve tested and validated the EPYC 4004 Series with the leading server operating systems, including Microsoft
Windows® Server 2022, Red Hat® Enterprise Linux 9.3 and 9.4, SUSE® Linux® Enterprise Server 15 SP5, and Ubuntu® 22.04"
