Intel · Xeon Platinum · 2021 · LGA4189
The Intel Xeon Platinum 8351N is a server processor with 36 cores, released in 2021 at an MSRP of $3,027. It is part of the Xeon Platinum lineup, using the Xeon Scalable platform, and fits the LGA4189 socket. Internally, it is built on the "Ice Lake-SP" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 72 threads for improved parallelism. The Xeon Platinum 8351N has a base clock of 2.4 GHz and can boost up to 3.5 GHz depending on workload and thermal headroom. Intel manufactures the "Ice Lake-SP" silicon on a 10nm process node. This processor supports DDR4 memory across 8 channels, up to 6TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 64 lanes of PCIe 4.0 available for storage, networking and accelerators. With a TDP of 225W, the Xeon Platinum 8351N runs hot and requires a capable cooling setup. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 54MB of L3 cache.
3rd Gen Xeon Scalable 'Ice Lake-SP' — Intel's first 10nm Xeon Scalable generation with 8-channel DDR4 and PCIe 4.0 support.
