Intel Xeon Platinum 8470N


The Intel Xeon Platinum 8470N is a server/workstation processor with 52 cores, launched in January 2023, at an MSRP of $9520. It is part of the Xeon Platinum lineup, using the Sapphire Rapids-SP architecture with Socket 4677.

Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 104 threads. To further increase overall system performance, up to two Xeon Platinum 8470N CPUs can work together in a multi-processor (SMP) configuration. Xeon Platinum 8470N has 97.5MB of L3 cache and operates at 1700 MHz by default, but can boost up to 3.6 GHz, depending on the workload. Intel is making the Xeon Platinum 8470N on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Xeon Platinum 8470N, which limits its overclocking potential.


With a TDP of 300 W, the Xeon Platinum 8470N is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR5 memory with an eight-channel interface. The highest officially supported memory speed is 4800 MHz, 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 computer, Xeon Platinum 8470N uses a PCI-Express Gen 5 connection. This processor lacks integrated graphics, you might need a graphics card.


Hardware virtualization is available on the Xeon Platinum 8470N, 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) can run on this processor, boosting performance for calculation-heavy applications.
