AMD has unveiled its new EPYC 4004 series of processors built on the Zen 4 architecture. Suited for small and medium businesses (SMBs), these processors stand out in AMD’s lineup as they can be installed on conventional motherboards with Socket AM5. This makes their integration into existing systems significantly easier.
The EPYC 4004 series consists of processors with a range from 4 to 16 cores, supporting 8 to 32 virtual threads. These chips have base clock speeds between 3.7 and 4.5 GHz, with a maximum speed limit ranging from 5.1 to 5.7 GHz. The stated Thermal Design Power (TDP) ranges from 65W to 170W.
Two chips within the new series, namely the 12-core 4484PX, and the 16-core 4584PX, are equipped with additional 3D V-Cache. This elevates the L3 cache memory up to a sizeable 128MB. The rest of the models feature L3 cache memory sizes that vary from 16 to 64MB. All EPYC 4004 processors come with integrated graphics based on the RDNA 2 architecture.
AMD asserts that the EPYC 4004 series offers support for up to 192GB of dual-channel DDR5-5200 ECC RAM. It can also accommodate up to 28 lanes of PCI Express 5.0. Additionally, it incorporates AMD’s RAIDXpert2 technology for RAID array configurations and TSME encryption.
Comparison with Intel Xeon E-2400
AMD contrasts the EPYC 4004 series with Intel’s Xeon E-2400 chips. The AMD processors offer twice as many cores, are more cost-effective per core, and have higher base and boost clock speeds. They also support faster and more high-capacity memory. AMD outperforms Intel in various use-case scenarios, as evidenced by the comparison charts above.
The price range for the EPYC 4004 series starts from $149 for the four-core 4124P model and goes up to $699 for the 16-core EPYC 4564P and EPYC 4584X models that feature 3D V-Cache. These processors are available in the market starting today.
