Xeon w5-2455X Details

Ranking #109 of 2060 in overall performance, the Intel Xeon w5-2455X delivers a compelling blend of multi-threaded power and single-core efficiency, despite being a relatively niche processor in the broader CPU landscape. Launched in early 2023, this 12-core, 24-thread server/workstation chip is built on Intel’s Sapphire Rapids architecture and is fabricated on a 10 nm process node. It operates at a base frequency of 3.2 GHz, with a turbo boost up to 4.6 GHz, making it one of the higher-frequency options in the Xeon W lineup. With a TDP of 200 W and a socket 4677 package, the w5-2455X is designed for robust workloads in professional environments where sustained performance and memory reliability are critical.

The processor supports DDR5 memory with a quad-channel interface, enabling a peak memory bandwidth of 153.6 GB/s and a rated speed of 4800 MT/s. ECC memory support is included, which is essential for mission-critical systems where data integrity is paramount. The 30 MB of L3 cache and support for PCIe 5.0 with 64 lanes further enhance its suitability for high-throughput applications. While it lacks integrated graphics, the Xeon w5-2455X relies on discrete GPUs, a common configuration in professional workstations.

In benchmark testing, the Xeon w5-2455X achieves a single-core score of 6529, placing it at #111 in the single-core rankings. This performance is competitive with mainstream desktop processors like the Core i9-11900KF and Core i7-8670, highlighting its strong per-thread efficiency. Its multicore score of 6694 ranks it at #132, indicating solid scalability across multiple cores. However, its overall score of 6595 places it just behind top-tier offerings such as the EPYC 7642 and Core Ultra 7 268V, showing that while it performs well, it doesn’t match the highest-end processors in the market.

Notable features include full support for Intel’s advanced instruction sets, such as AVX-512, FMA3, and SHA extensions, which benefit scientific computing and encryption tasks. Virtualization capabilities like Intel VT-x and VT-d, along with Intel vPro, make it ideal for enterprise environments. The processor also supports hardware-based encryption, AES-NI, and transactional memory via TSX, enhancing performance in security and database applications.

As of March 2026, the Xeon w5-2455X remains a strong option for workstation users requiring high core counts, fast memory bandwidth, and ECC support. It sits between mainstream high-end desktop CPUs and server-grade processors, offering a balance of performance and efficiency. While it doesn’t dominate in any single category, its versatility makes it well-suited for content creation, engineering simulations, and virtualization tasks where both single-core responsiveness and multi-threaded throughput are important.
