Product Descriptions

The Intel Xeon w5-2455X is a server/workstation processor with 12 cores. It is part of the Xeon W lineup, using the Sapphire Rapids architecture with Socket 4677. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 24 threads. Xeon w5-2455X has 30 MB of L3 cache and operates at 3.2 GHz by default, but can boost up to 4.6 GHz, depending on the workload. Intel is making the Xeon w5-2455X on a 10 nm production node, the transistor count is unknown. You may freely adjust the unlocked multiplier on Xeon w5-2455X, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.

With a TDP of 200 W, the Xeon w5-2455X is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR5 memory with a quad-channel interface. The highest officially supported memory speed is 4800 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 w5-2455X 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 w5-2455X, 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. Besides AVX, Intel has added support for the newer AVX2 and AVX-512 instructions, too.
