The Intel Xeon Platinum 8321HC is a server/workstation processor with 26 cores, launched in April 2020. It is part of the Xeon Platinum lineup, using the Cascade Lake architecture with Socket LGA4189. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 52 threads. To further increase overall system performance, up to eight Xeon Platinum 8321HC CPUs can work together in a multi-processor (SMP) configuration. Xeon Platinum 8321HC has 35.75 MB of L3 cache and operates at 2.5 GHz by default, but can boost up to 3.5 GHz, depending on the workload. Intel is making the Xeon Platinum 8321HC on a 14 nm production node. The multiplier is locked on Xeon Platinum 8321HC, which limits its overclocking potential. With a TDP of 205 W, the Xeon Platinum 8321HC consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR4 memory with a six-channel interface. The highest officially supported memory speed is 3200 MT/s. 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 computer, Xeon Platinum 8321HC uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, you might need a graphics card. Hardware virtualization is available on the Xeon Platinum 8321HC, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX-512) will run on this processor, boosting performance for calculation-heavy applications.
