Xeon D

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, and a larger cache. 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 PCIe root complex, and USB and SATA controllers.

Skylake

Main article: Skylake (microarchitecture)

The Skylake (D-2100) 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]
