The Intel Xeon W-2255 was a high-performance server/workstation processor with 10 cores, launched in October 2019. It is part of the Xeon W lineup, using the Cascade Lake architecture with Socket LGA 2066. Thanks to Intel Hyper-Threading technology, the core-count is effectively doubled, to 20 threads. The Xeon W-2255 features a base clock speed of 3.7 GHz and can boost up to 4.7 GHz depending on workload, with a substantial 19.25 MB of L3 cache for enhanced performance. Intel manufactured the Xeon W-2255 on a 14 nm production process, incorporating advanced transistor technology for improved efficiency and performance.

With a TDP of 165 W, the Xeon W-2255 demands robust cooling solutions to maintain optimal operating temperatures. The processor supports DDR4 memory with a quad-channel interface, running at speeds up to 2933 MHz, ensuring high bandwidth for data-intensive applications. ECC (Error-Correcting Code) memory is also supported, a critical feature for mission-critical workloads where data integrity is paramount.

For system connectivity, the Xeon W-2255 utilizes PCI-Express 3.0, providing ample bandwidth for high-speed peripherals and storage devices. This processor does not include integrated graphics, so a dedicated graphics card is required for display output. Hardware virtualization support (Intel VT-x) is included, significantly enhancing virtual machine performance for enterprise and professional workloads. Additionally, the processor supports advanced instruction sets such as AVX-512, making it well-suited for demanding computational tasks in scientific, engineering, and creative applications.

The Xeon W-2255 is designed for professional workstations and servers where multi-threaded performance, memory bandwidth, and reliability are essential. Its unlocked multiplier allows for limited overclocking potential, though thermal constraints must be carefully managed due to its high power consumption.
