EPYC 7401

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.

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.

Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Xeon Silver 4114.

The EPYC 7401 has a rated TDP (Thermal Design Power) of 170 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: Premium Server Cooler.

At an average price of $450 (MSRP: $1500), the EPYC 7401 delivers 123 PassMark points per dollar. Performance ranking position: #165 out of all indexed processors.
