Intel Xeon W 2155 CPU

The Intel Xeon W-2155 is a high-performance processor designed for use in workstations and servers. It was introduced in the fourth quarter of 2017 and is still a relevant option in today's market. The Xeon W-2155 belongs to the Skylake-SP family of processors and is manufactured using a 14nm process. In this article, we will delve into the features and performance of the Intel Xeon W-2155 processor.

Specifications

The Intel Xeon W-2155 has 10 cores and 20 threads, with a base clock speed of 3.3 GHz and a maximum turbo frequency of 4.5 GHz. It has a thermal design power of 140W, which is higher than most consumer-grade processors. The processor also has 13.75MB of L3 cache and supports up to 512GB of DDR4 2666 memory.

Like its predecessors, the Xeon W-2155 supports ECC memory, which is crucial for workstations and servers that are used for critical tasks where data integrity is essential.

Performance

The Intel Xeon W-2155 processor delivers exceptional performance in both single-threaded and multi-threaded applications. In single-threaded applications, it performs similarly to other high-end processors such as the Intel Core i9-9900K. However, where it truly shines is in multi-threaded applications. The Xeon W-2155 outperforms consumer-grade processors in tasks that can utilize all 20 threads, such as rendering or video encoding.

The Xeon W-2155 also supports Intel Turbo Boost Max Technology 3.0, which automatically identifies the best-performing core on the processor and directs critical workloads to it. This can provide an extra boost in performance for single-threaded applications that are sensitive to clock speed.

The Xeon W-2155 also supports Intel Advanced Vector Extensions 512 (AVX-512), which allows for enhanced performance in applications that require heavy computing. This can be useful in scientific simulations or machine learning tasks, where high-performance computing is essential.

Like its predecessors, the Xeon W-2155 lags behind consumer-grade processors in gaming performance. However, its high core count, support for ECC memory, and advanced technologies make it an excellent choice for workstations and servers that require top-tier performance for critical tasks.
