The Intel Xeon Silver 4514Y is a server/workstation processor with 16 cores, launched in December 2023, at an MSRP of $780. It is part of the Xeon Silver lineup, using the Emerald Rapids-SP architecture with Socket 4677. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 32 threads. To further increase overall system performance, up to two Xeon Silver 4514Y CPUs can link up in a multi-processor (SMP) configuration. Xeon Silver 4514Y has 30 MB of L3 cache and operates at 2000 MHz by default, but can boost up to 3.4 GHz, depending on the workload. Intel is building the Xeon Silver 4514Y on a 10 nm production process, the transistor count is unknown. The multiplier is locked on Xeon Silver 4514Y, which limits its overclocking capabilities.
With a TDP of 150 W, the Xeon Silver 4514Y 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 4400 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 Silver 4514Y 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 Silver 4514Y, 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.
