Xeon D is a family of 64-bit multi-core x86 microserver single-chip processors introduced by Intel in March of 2015. Xeon D chips are aimed at filling the gap between the Atom and the Xeon E3 families. Targeting the low-end server market, the Xeon D family puts priority on efficiency and networking - areas where dense, lower-power, lightweight hyperscale workloads are expected.

History

The Xeon D began as a joint collaboration between Facebook and Intel in 2013. Yosemite is the codename for Facebook's open source modular chassis for the highly-concurrent but lower-power microservers. The design calls for dense nodes of lower power but highly concurrent workload which tends to be mostly memory-bandwidth-bound. While early designs where mostly based on the Atom SoCs, their performance proved to be too much of a bottleneck on its own. Xeon D is a middle-tier family that's a step above Atom in terms of performance, but below Xeon E3 power-wise. Xeon D is largely driven by high concurrency and better memory capabilities.

Currently, Intel offers two series of Xeon D parts - dense low-power and dense high-power parts.

D-2100 Series (Skylake)

Main articles: Skylake (server) Microarchitecture and Skylake DE core

Introduced in February 2018, Xeon D-2100 series processors are based on the Skylake microarchitecture. Those low-power variant range from 4 to 18 cores with hyperthreading support. As with the previous generations, those chips are also a single-chip solution - the Lewisburg chipset is incorporated into the same package as the processor. Being based on the new Skylake microarchitecture means those parts are also based on the mesh architecture which brought a much bigger L2 cache and supports twice as many memory channels. Additionally, all models also support AVX-512 with a single execution unit.

SKUs are suffixed with either I, T, and N or combination of multiple of those options:

• I - Integrated Ethernet
• T - High Temperature (90° T_CASE) and extended reliability support
• N - Integrated Ethernet and Intel's QuickAssist technology

All models have all the following features in common:

• Mem: Up 512 GiB of quad-channel DDR4 Memory
  • DPC RDIMM and LRDIMM \w ECC
• I/O: 32 PCIe 3.0 Lanes + 20 configurable High-Speed I/O (HSIO) lanes
• TDP: < 110 W
• ISA: Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2, AVX512F, AVX512CD, AVX512BW, AVX512DQ, AVX512VL)
• Features: Speed Shift, vPro, VT-x/EPT, VT-d, TBT 2.0, TSX, TXT, SpeedStep, Secure Key, MPX, OS Guard, and RAS.
