The Intel Xeon W-1350 was a server/workstation processor with 6 cores, launched in May 2021, at an MSRP of $255. It is part of the Xeon W lineup, using the Rocket Lake-S architecture with Socket 1200. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Xeon W-1350 has 12 MB of L3 cache and operates at 3.3 GHz by default, but can boost up to 5 GHz, depending on the workload. Intel is building the Xeon W-1350 on a 14 nm production process, the transistor count is unknown. The multiplier is locked on Xeon W-1350, which limits its overclocking capabilities.
With a TDP of 80 W, the Xeon W-1350 consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR4 memory with a dual-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 computer, Xeon W-1350 uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics P750 integrated graphics solution.
Hardware virtualization is available on the Xeon W-1350, 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.
