Intel Xeon W5-2455X 12 Cores 24 Threads 4.6GHz E (LGA 4677) PK8071305127200 CPU

Single-Socket Workstation and Edge Server CPU platform built on Sapphire Rapids with the Intel Xeon W5-2455X

The Intel Xeon W5-2455X (SKU PK8071305127200) targets LGA4677 single-socket workstations and compact servers where predictable throughput, ECC memory integrity, and modern I/O are mandatory. Built on the Sapphire Rapids generation, the Intel Xeon W5-2455X provides 12 cores and 24 threads with a 3.2GHz base and up to 4.6GHz turbo, aligning well with mixed interactive and batch workloads that demand strong per-core performance.

For memory architecture, the Intel Xeon W5-2455X enables ECC DDR5 up to 4800 MT/s, supporting higher bandwidth headroom for CAD/CAE datasets, EDA toolchains, and virtualization hosts that are sensitive to memory stalls. Expansion is optimized through 64 PCIe 5.0 lanes, allowing high-speed NVMe storage backplanes and GPU or accelerator attachment without compromising lane allocation. This platform is well suited to NVMe-centric storage layouts and fast network adapters, enabling low-latency infrastructure services and development environments where AMX and AVX-512 accelerate inference, analytics, and vectorized compute paths.

Why Choose the Intel Xeon W5-2455X?

The Intel Xeon W5-2455X delivers a pragmatic density-to-performance balance for 1S deployments by combining workstation-class responsiveness with server-grade reliability features. With PCIe 5.0 lane availability, ECC memory support, and hardware virtualization capabilities such as VT-x and VT-d, the Intel Xeon W5-2455X scales cleanly from engineering desktops to edge virtualization nodes while maintaining consistent platform behavior and predictable expansion planning.

Intel designs Xeon platforms around validated silicon enablement, long-term ecosystem compatibility, and security technologies such as AES-NI, Boot Guard, TXT, and CET to support modern data centre operational standards and compliance-driven environments.
