'''Xeon D''' is a family of {{arch|64}} 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 {{intel|Atom}} and the {{intel|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 {{intel|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 {{intel|Atom}} in terms of performance, but below {{intel|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.

First-generation of dense low-power Xeon D parts were introduced in early [[2015]] and are based on the {{intel|Broadwell (server)|Broadwell|l=arch}} microarchitecture. Fabricated on their [[14 nm process]], those parts incorporate up to [[16 cores|sixteen cores]] with a [[TDP]] of up to 65 W.

* '''TDP:''' 20-65 W
* '''Mem:''' 128 GiB dual-channel DDR4 ECC memory up to 2133/2400 MT/s. (128 GiB @ [[RDIMM]] 32 GiB/DIMM, 64 GiB @ UDIMM/SODIMM 16 GiB/DIMM)
* '''I/O:''' 32 PCIe 3/2 lanes (x24 Gen3 + x8 Gen2)
* '''ISA:''' Everything up to {{x86|AVX2}} ({{x86|SMM}}, {{x86|FPU}}, {{x86|NX}}, {{x86|MMX}}, {{x86|SSE}}, {{x86|SSE2}}, {{x86|SSE3}}, {{x86|SSSE3}}, {{x86|SSE4.1}}, {{x86|SSE4.2}}, {{x86|AES}}, {{x86|AVX}}, {{x86|FMA3}}, and {{x86|AVX2}})
* '''Features:''' {{intel|SpeedStep}}, {{intel|VT-x}}, {{intel|TSX}}, {{intel|TXT}}, {{intel|Secure Key}}, and {{intel|OS Guard}}

All models are a single-chip solution, meaning both the [[CPU]] [[die]] and the [[chipset]] die are packaged together on the same substrate.

Intel introduced a refresh of the {{intel|Broadwell DE|l=core}} in early 2019, formerly codename {{intel|Hewitt Lake|l=core}}. Like the prior generation, those new processors are also based on the {{intel|Broadwell (server)|Broadwell|l=arch}} microarchitecture. Fabricated on their [[14 nm process]], those parts incorporate up to [[16 cores|sixteen cores]] with a [[TDP]] of up to 65 W. The new SKUs feature higher frequencies at similar TDPs, improving the performance per watt.

* '''TDP:''' 27-65 W
* '''Mem:''' 128 GiB dual-channel DDR4 ECC memory up to 2133/2400 MT/s. (128 GiB @ [[RDIMM]] 32 GiB/DIMM, 64 GiB @ UDIMM/SODIMM 16 GiB/DIMM)

== Dense High-Power ==
=== D-2100 Series (Skylake) ===
{{main|intel/microarchitectures/skylake (server)|intel/cores/skylake de|l1=Skylake (server) Microarchitecture|l2=Skylake DE core}}
Introduced in February [[2018]], Xeon D-2100 series processors are based on the {{intel|Skylake (server)|Skylake microarchitecture|l=arch}}. Those low-power variant range from [[4 cores|4]] to [[18 cores]] with {{intel|hyperthreading}} support. As with the previous generations, those chips are also a single-chip solution - the {{intel|Lewisburg|l=chipset}} [[chipset]] is incorporated into the same package as the processor. Being based on the new {{intel|Skylake (server)|Skylake microarchitecture|l=arch}} 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 {{x86|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° [[tcase|T<sub>CASE</sub>]]) and extended reliability support
* '''N''' - Integrated Ethernet and Intel's {{intel|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:''' {{intel|Speed Shift}}, {{intel|vPro}}, {{intel|VT-x}}/{{intel|EPT}}, {{intel|VT-d}}, {{intel|TBT 2.0}}, {{intel|TSX}}, {{intel|TXT}}, {{intel|SpeedStep}}, {{intel|Secure Key}}, {{intel|MPX}}, {{intel|OS Guard}}, and {{intel|RAS}}.
