Xeon Platinum 8351N Details

As of March 2026, the Intel Xeon Platinum 8351N remains a powerful server and workstation processor, though its 2021 launch places it in the older segment of current offerings. Despite its age, it continues to hold relevance in enterprise environments due to its robust multicore performance and enterprise-grade features. The processor is built on Intel's 10 nm Ice Lake-SP architecture and is designed for high-end server and workstation platforms, utilizing the FC-LGA4189 socket and supporting up to 225 W of thermal design power. This high TDP reflects its demanding workloads and necessitates serious cooling infrastructure, making it unsuitable for mainstream desktop use.

The Xeon Platinum 8351N features 36 cores and 72 threads thanks to Intel's Simultaneous Multithreading (SMT) technology, allowing it to handle highly parallelized workloads efficiently. With a base clock of 2.4 GHz and a turbo frequency of up to 3.5 GHz, it delivers strong single-threaded performance, especially when leveraging AVX-512 and AVX2 instruction sets for compute-intensive applications. The processor includes a substantial 51.5 MiB L3 cache, paired with 0.061 MiB of L1 and 0.954 MiB of L2 cache, enhancing data throughput and reducing latency in memory-intensive tasks.

In benchmark testing, the Xeon Platinum 8351N achieves an overall score of 6,231, placing it at #171 among 2,060 processors. Its multicore performance scores 7,195, ranking it #84, while its single-core score of 5,588 secures a position at #491. This performance profile highlights a strong focus on multi-threaded processing, with its multicore ranking significantly higher than its single-core rank—indicating its design is optimized for sustained workloads rather than burst performance. It outperforms many mainstream desktop CPUs, including the Core i9-12900KS and Ryzen 7 9800X3D, but trails behind leading-edge processors such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K.

The processor supports DDR4 memory at speeds up to 2933 MT/s via an eight-channel memory interface, delivering a memory bandwidth of 187.7 GB/s. ECC memory support ensures data integrity in mission-critical environments, a key advantage for servers and professional workstations. It also supports PCIe 4.0 with 64 lanes directly from the CPU, enabling high-speed storage and expansion options. However, it lacks integrated graphics, requiring a discrete GPU for any visual output.

Technologically, the Xeon Platinum 8351N supports advanced features including Intel VT-x, VT-d, and TXT for hardware virtualization, making it ideal for virtualized environments. It also includes Intel vPro for enhanced manageability and security, further solidifying its enterprise appeal. While it lacks AVX-512 support in some configurations, the presence of AVX and AVX2 ensures compatibility with a broad range of scientific, engineering, and data processing applications.

In conclusion, the Xeon Platinum 8351N is a well-rounded server/workstation CPU suited for data centers, virtualization, and high-performance computing environments. While newer processors have surpassed it in both single-core and overall performance, its multicore strength, memory bandwidth, and enterprise features ensure it remains a viable option in professional settings where reliability and scalability are paramount.
