AMD launches EPYC 4004 series of entry-level server processors

As AMD’s share of the x86 processor market continues to grow, they are venturing into new territories. In the entry-level server market, which was previously dominated by Intel’s Xeon E series, AMD has introduced the EPYC 4004 processor to capture this segment. The EPYC 4004 is the latest addition to the Zen 4 EPYC family, tailored for small and medium-sized businesses and hosting IT companies. It is also AMD’s first EPYC processor to use a consumer-grade processor socket.

The EPYC 4004 can offer up to 16 Zen 4 cores, with a maximum of 32 threads, a top clock speed of 5.7GHz, and support for dual-channel DDR5-5200 ECC memory with a maximum capacity of 192GB. It can provide up to 28 PCIe 5.0 lanes and integrates an RDNA 2 architecture iGPU. The specifications are similar to desktop Ryzen processors, and the platform includes server-specific features like RAIDXpert2 and AMD TSME. As an entry-level server processor, it supports single-socket systems.

The EPYC 4004 features an X-suffix variant with 3D V-Cache, offering up to 128MB of L3 cache, while standard dual-CCD processors have up to 64MB of L3 cache. This means, like the Ryzen X3D processors, only one CCD is equipped with 3D V-Cache.

The naming convention for the EPYC 4004 is illustrated below. The thousands digit denotes the series name, the hundreds digit represents the number of cores, ranging from 0 to 5, indicating 2, 4, 6, 8, 12, and 16 cores respectively. The tens digit signifies performance, and the units digit represents the generation of the Zen architecture. The P suffix, present in all EPYC 4004 processors, indicates a single-socket system, while the X suffix denotes 3D V-Cache.

Below is an official performance comparison between the EPYC 4004 and the Xeon E-2400 processors, specifically in integer computing power. As the Xeon E-2400 has a maximum of only 8 P-Cores, the EPYC 4004, with up to 16 cores, naturally holds an advantage. Even when comparing the same number of cores, the EPYC 4004 does not fall behind.

The EPYC 4004 lineup includes eight products, with TDPs ranging from 65W to 170W, encompassing 4 to 16 cores, including two models equipped with 3D V-Cache. AMD indicated that machines based on the EPYC 4004 will soon be available from Altos (an Acer subsidiary), ASRock, Gigabyte, MSI, Supermicro, and Tyan, with more OEMs to follow. Additionally, dedicated hosting providers OVHcloud and Ionos will offer EPYC 4004-based servers to their clients. More providers are qualifying AMD‘s new platform, with plans to launch within the year.
