Description
The AMD EPYC™ 9455P is a high-performance server processor designed for demanding enterprise, virtualization, analytics, engineering, and AI-enabled data center workloads. Featuring 48 CPU cores and 96 threads, the EPYC 9455P delivers a 3.15 GHz base clock, 4.1 GHz all-core boost speed, and maximum boost frequencies of up to 4.4 GHz.
Built for the AMD SP5 platform and optimized for single-socket server configurations, the EPYC 9455P supports 12-channel DDR5 memory at speeds up to 6400 MT/s, providing up to 614 GB/s of memory bandwidth per socket. It also offers 128 lanes of PCIe® 5.0 connectivity, enabling high-bandwidth connections for storage, networking, accelerators, and other data center infrastructure.
With 256 MB of L3 cache, a configurable TDP range of 240W to 300W, and support for technologies including AMD Infinity Guard and AMD Infinity Architecture, the EPYC 9455P is engineered to support business-critical applications where compute density, memory bandwidth, security, and scalability are essential.
Ideal workloads include virtualization and VM density, VDI, analytics, application development and testing, CAE/CFD/FEA engineering applications, enterprise resource management platforms, and high-capacity database environments.
