EPYC 7401 Details

The AMD EPYC 7401 stands as a powerful server-grade processor designed for high-performance computing environments, leveraging AMD's Zen microarchitecture built on a 14 nm process. Released in June 2017, it represents a generation of server CPUs that emphasize scalability and multi-threaded performance, though its age places it well behind current offerings. Despite its maturity, the EPYC 7401 remains a relevant option for workloads requiring extensive parallel processing and ECC memory support, particularly in enterprise and data center deployments where reliability and longevity are critical.

At the core of this processor are 24 physical cores, each capable of handling two threads through Simultaneous Multithreading (SMT), resulting in a total of 48 threads. This enables exceptional performance in multi-threaded applications such as virtualization, rendering, and scientific simulations. The base clock speed is 2.0 GHz, with a turbo frequency reaching up to 3.0 GHz on lower core counts, though performance scales down with increased core utilization. The chip features a substantial cache hierarchy, including 2.25 MiB of L1 cache (0.75 MiB L1D and 1.5 MiB L1I), 12 MiB of L2 cache, and a large 64 MiB L3 cache, which helps maintain high data throughput under heavy workloads.

The EPYC 7401 operates within a 155 W TDP and is packaged in the FCLGA-4094 socket, compatible with Socket SP3 motherboards. It supports up to 2097152 MiB (2 TB) of DDR4-2666 memory across eight channels, delivering a peak memory bandwidth of 170.6 GB/s. This makes it well-suited for memory-intensive applications, while ECC support ensures data integrity in mission-critical environments. The processor also includes a PCIe Gen 3 interface with up to 128 lanes, enabling robust expansion capabilities for high-speed storage and networking components.

In terms of performance, the EPYC 7401 achieves an overall score of 6480, ranking #119 among 2060 processors, with a single-core score of 5480 (#565) and a multicore score of 7981 (#30). These results indicate that while it is not competitive with modern high-end desktop or workstation processors, it holds its own in the server segment, particularly in multicore scenarios. Its multicore performance surpasses many consumer-grade CPUs, including the Ryzen 9 7950X and Core i9-14900KF, though it trails behind more recent AMD and Intel offerings in single-threaded tasks.

Key features include support for advanced vector extensions (AVX and AVX2), AES encryption, and AMD-V virtualization technologies, enhancing performance and security in virtualized environments. The absence of integrated graphics means that a discrete GPU is required for display output, which is typical for server processors. As of March 2026, the EPYC 7401 remains a viable choice for legacy server upgrades or specialized workloads where its balance of core count, memory support, and power efficiency is advantageous, though newer generations offer significantly higher performance and efficiency.
