EPYC 9554

The EPYC 9554 is a 64-core / 128-thread processor based on the Genoa (2022−2023) architecture, manufactured on a 5 nm, 6 nm process node. It reaches a maximum boost clock of 3.75 GHz from a base frequency of 3.1 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 256 MB (total) L3 cache (3D V-Cache technology), this processor has a significant gaming advantage — the large cache drastically reduces memory latency in game engines., plus 1 MB (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 104,336, placing it in the Enthusiast performance tier as a Aging generation product.

The EPYC 9554 fits into the SP5 socket and supports PCIe 5.0 with 128 total PCIe lanes for expansion cards and storage. It supports DDR5-4800 memory at speeds up to DDR5-4800 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 6 TB across 12 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers.

The EPYC 9554 is primarily designed for Data Center. Virtualization: AMD-V, SEV-SNP — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Xeon 8468.

The EPYC 9554 has a rated TDP (Thermal Design Power) of 360 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: Server Grade Air/Liquid.

At an average price of $2,795 (MSRP: $9087), the EPYC 9554 delivers 37 PassMark points per dollar. Performance ranking position: #28 out of all indexed processors.
