 The Skylake-SP (Scalable Processor) generation of Intel Xeon processors was introduced in 2017, and it is designed for use in data center and enterprise server environments. It offers significant improvements in performance, scalability, and efficiency over the previous generation, the Broadwell-EP Xeon processors. One of the key features of the Skylake-SP processors is the increased number of cores, up to 28 cores per processor. This increase provides you more processing power, allowing for better performance in applications that require a lot of parallel processing, such as data analytics, virtualization, and high-performance computing. Another important enhancement of the Skylake-SP processors is the support for Intel's AVX-512 instruction set. This instruction set offers significant improvements in performance for compute-intensive workloads like machine learning, deep learning, and scientific simulations. Offering advanced features for memory and I/O, allows for greater memory bandwidth and I/O performance, making the processors suitable for workloads that require high data throughput.

 The Skylake-SP processors are also designed for better energy efficiency, with a new mesh architecture that improves inter-core communication and reduces latency. Additionally, Intel has introduced new power management features that help to optimize energy usage and reduce power consumption. Overall, the Skylake-SP generation of Intel Xeon processors offers significant improvements in performance, scalability, efficiency, and advanced features, making them well-suited for use in data center and enterprise server environments.
