AMD's EPYC 4004 series offers high-performing, cost-effective server chips based on the Zen 4 architecture, competing with Intel's Xeon-E family and targeting small business and entry-level server markets.
- AMD's EPYC 4004 series offers high-performing cores with clock speeds up to 5.1GHz, making them ideal for demanding workloads.
- The EPYC 4004 series fills a niche in the server market that Intel does not, offering 12 and 16 core options in the entry-level segment.
- The EPYC 4004 series comes with all the expected features of the AM5 platform, including PCIe 5.0 support, DDR5 memory, and integrated graphics.
AMD has been making significant strides in the server market since its resurgence as a major competitor in the x86 CPU scene. With their EPYC processors, they have been steadily chipping away at Intel’s dominance in the lucrative server market. Now, AMD is targeting the entry-level 1P server market with their new EPYC 4004 series processors.
The EPYC 4004 family essentially replaces AMD’s Ryzen chips for server use. While Ryzen for servers was not a dedicated product lineup, it has been a segment within the company since 2019, catering to smaller-scale hosting providers. With the upgrade to EPYC status, AMD is repositioning this hardware ecosystem as a proper lineup with dedicated chips and additional features suitable for EPYC processors. This expansion also includes small business users, broadening the market segments AMD is targeting.
The EPYC 4004 series is based on AMD’s AM5 platform and Raphael processors, which are part of the Ryzen 7000 series. These EPYC counterparts are essentially rebranded Ryzen 7000 SKUs, offering the same core counts, clock speeds, and TDPs. The only exception is the entry-level 4-core 4124P chip.
All the chips in the EPYC 4004 series are based on AMD’s Zen 4 architecture. While they may have fewer cores compared to other EPYC processors, they are high-performing cores, with clock speeds that don’t go below 5.1GHz. Some SKUs in the series also feature AMD’s 3D V-Cache technology, which stacks cache on top of the CCDs, resulting in a total of 128MB of L3 cache.
In terms of energy efficiency, the EPYC 4004 series is not particularly efficient compared to other EPYC processors. However, these chips are designed to be cost-effective rather than energy-efficient. The EPYC 8004 series, with its many-core Zen 4c designs, focuses more on energy efficiency.
The EPYC 4004 series comes with all the expected features of the AM5 platform, including PCIe 5.0 support, DDR5 memory, and integrated graphics. ECC is officially supported on these server chips, although only UDIMMs are supported, not RDIMMs.
While AMD has not disclosed the specific chipset paired with the EPYC 4004 processors, it is likely to be an ASMedia-designed I/O chipset. The EPYC 4004 platform offers additional enterprise features at the motherboard level, such as baseboard management controller (BMC) support, software RAID, and official server OS support.
AMD’s EPYC 4004 chips directly compete with Intel’s entry-level Xeon-E family. Unlike Intel, AMD offers 12 and 16 core chips in this segment, filling a niche that Intel does not. Additionally, AMD’s core counts align well with Windows Server 2022 licensing, allowing server owners to maximize their license with top-end EPYC 4004 chips.
In terms of performance, AMD’s EPYC processors have an advantage in highly multi-threaded workloads due to their significant core count advantage over Intel’s products. However, this also results in higher power consumption compared to Intel’s lower wattage chips.
AMD has launched the EPYC 4004 product stack immediately, with many server partners already on board. The availability of core hardware means there won’t be a significant ramp-up period for these processors.
