The Intel Xeon w7-2475X is a server/workstation processor with 20 cores, launched in February 2023, at an MSRP of $1789. 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 40 threads. Xeon w7-2475X has 37.5 MB of L3 cache and operates at 2.6 GHz by default, but can boost up to 4.8 GHz, depending on the workload. Intel is making the Xeon w7-2475X on a 10 nm production node, the transistor count is unknown. You may freely adjust the unlocked multiplier on Xeon w7-2475X, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 225 W, the Xeon w7-2475X 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 computer, Xeon w7-2475X 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 w7-2475X, 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.
