EPYC 9755

The EPYC 9755 is a 128-core / 256-thread processor based on the Turin (2024) architecture, manufactured on a 4 nm process node. It reaches a maximum boost clock of 4.1 GHz from a base frequency of 2.7 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 512 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 80 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 166,328, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,800, while multi-core reaches 29,300.

The EPYC 9755 fits into the SP5 socket and supports PCIe 5.0 with 128 total PCIe lanes for expansion cards and storage. It supports DDR5 memory at speeds up to DDR5-6000 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 9 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 9755 is primarily designed for Data Center / Cloud Computing. Virtualization: AMD-V, SEV-SNP — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Xeon 6980P.

The EPYC 9755 has a rated TDP (Thermal Design Power) of 500 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 $10,931 (MSRP: $12984), the EPYC 9755 delivers 15 PassMark points per dollar. Performance ranking position: #2 out of all indexed processors.
