Technical Analysis
Detailed breakdown of EPYC 7401 specifications and capabilities.
Processing Power
The EPYC 7401 is a 24-core / 48-thread processor based on the Naples (2017−2018) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3 GHz from a base frequency of 2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 64 MB (total) of L3 cache, plus 512K (per core) of L2 cache and 96K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 55,280, placing it in the Enthusiast performance tier as a Legacy generation product.

Memory & Platform
The EPYC 7401 fits into the TR4 socket and supports PCIe 4.0 with 128 total PCIe lanes for expansion cards and storage. It supports DDR4 Eight-channel memory at speeds up to 2666 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 2048 across 8 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: None — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.
