The Intel Xeon W-3345 is a server/workstation processor with 24 cores, launched in July 2021. It is part of the Xeon W lineup, using the Ice Lake-W architecture with Socket 4189. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 48 threads. To further increase overall system performance, up to two Xeon W-3345 CPUs can link up in a multi-processor (SMP) configuration. Xeon W-3345 has 36 MB of L3 cache and operates at 3 GHz by default, but can boost up to 4 GHz, depending on the workload. Intel is building the Xeon W-3345 on a 10 nm production process, the transistor count is unknown. The multiplier is locked on Xeon W-3345, which limits its overclocking capabilities.
With a TDP of 250 W, the Xeon W-3345 is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR4 memory with an eight-channel interface. The highest officially supported memory speed is 3200 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 W-3345 uses a PCI-Express Gen 4 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon W-3345, 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 has added support for the newer AVX2 and AVX-512 instructions, too.
