The Intel Xeon Platinum 9282 is a server/workstation processor with 56 cores, launched in April 2019. It is part of the Xeon Platinum lineup, using the Cascade Lake-AP architecture with BGA5903. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 112 threads. To further increase overall system performance, up to eight Xeon Platinum 9282 CPUs can link up in a multi-processor (SMP) configuration. Xeon Platinum 9282 has 77MB of L3 cache and operates at 2.6 GHz by default, but can boost up to 3.8 GHz, depending on the workload. Intel is building the Xeon Platinum 9282 on a 14 nm production process using 8,000 million transistors. The multiplier is locked on Xeon Platinum 9282, which limits its overclocking capabilities.
With a TDP of 400 W, the Xeon Platinum 9282 is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR4 memory. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon Platinum 9282, 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 is including the newer AVX2 standard, too, but not AVX-512.
