The Xeon D is a brand of x86 system on a chip designed, manufactured, and marketed by Intel, targeted at the microserver market.[1] It was announced in 2014, with the first products released in 2015. Related to the Xeon brand of workstation and server processors are based on the same architecture as server-grade CPUs, with support for ECC memory, higher core counts, support for larger amounts of RAM, larger cache memory. Unique to the Xeon D line, emphasis was also made on low power consumption, and integrated hardware blocks such as a network interface controllers, a PCI express root complex, and USB and SATA controllers.

Design Goals[edit]

The Xeon D was designed to offer better performance per watt compared to the Xeon E3 and better absolute performance compared to the Atom processors, while operating at lower power and higher densities than Xeon E5 processors.[2] Particularly, the Xeon D was designed to compete with emerging ARM microarchitecture based server solutions,[3] by offering superior single core performance.[4]

Skylake Based[edit]

A second generation of Xeon D products were released in February 2018. Updates included an increased maximum number of cores, the Skylake microarchitecture, AVX-512 acceleration, and cryptographic acceleration.[5] The second generation also offered increased clock speeds, resulting in greater performance, though the maximum thermal design power also increased.[6] However, the level of AVX-512 support is unclear by product, with higher end products having greater performance than the listed specifications.[7]

Cascade Lake Based[edit]

Intel announced the next generation of Xeon D products, codenamed Hewitt Lake in February 2019.[8]
