Connectivity
Intel Socket 4189
The Intel Xeon Platinum 8351N is a server/workstation processor with 36 cores, launched in April 2021. It is part of the Xeon Platinum lineup, using the Ice Lake-SP architecture with Socket 4189. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 72 threads. Xeon Platinum 8351N has 54 MB of L3 cache and operates at 2.4 GHz by default, but can boost up to 3.5 GHz, depending on the workload. Intel is building the Xeon Platinum 8351N on a 10 nm production process, the transistor count is unknown. The multiplier is locked on Xeon Platinum 8351N, which limits its overclocking capabilities.
With a TDP of 225 W, the Xeon Platinum 8351N is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR4 memory with an eight-channel interface. The highest officially supported memory speed is 2933 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Xeon Platinum 8351N uses a PCI-Express Gen 4 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon Platinum 8351N, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel has added support for the newer AVX2 and AVX-512 instructions, too.
