'''Skylake SP''' ('''{{intel|Skylake|l=arch}} Scalable Performance''') is the code name for Intel's series of server [[multiprocessors]] based on the {{intel|Skylake|l=arch}} microarchitecture as part of the {{intel|Purley|l=platform}} platform serving as a successor to both {{intel|Broadwell EX|l=core}} and {{intel|Broadwell EP|l=core}}. These chips support up to 8-way multiprocessing, up to [[28 cores]], and incorporate a new {{x86|AVX-512}} [[x86]] {{x86|extension}}. Skylake SP-based chips are manufactured on an enhanced [[14 nm process|14nm+ process]] and utilize the {{intel|Lewisburg|l=chipset}} chipset. Skylake SP-based models are branded as the [[processor families]]: {{intel|Xeon Bronze}}, {{intel|Xeon Silver}}, {{intel|Xeon Gold}}, and {{intel|Xeon Platinum}}.

== Overview ==
Skylake SP processors are based on Intel's {{intel|Skylake|l=arch}} server configuration which incorporates a very large number of enhancements and improvements over its predecessor. Those processors support between two and eight-way multi-processing (the exact support depends on the Xeon family) and with all models supporting hex-chanel 768 GiB of DDR4 ECC memory or 1.5 GiB for extended memory models.

Skylake SP processors utilize the new {{intel|FCLGA-3647}} package (which makes use of "Socket P"). Those use the {{intel|Lewisburg}} chipset ({{intel|Platform Controller Hub|HUB}}) via 4 PCIe3 lanes using Intel's proprietary {{intel|Direct Media Interface}} 3.0 (DMI 3.0), allowing for 8 GT/s transfer rate per lane. When in multi-socket configuration, the microprocessor is connected to the other processors via the {{intel|Ultra Path Interconnect}} (UPI) links which Intel introduced with Skylake SP as well, replacing and obsoleting the older {{intel|QuickPath Interconnect}} (QPI) operating. Depending on the model, there may be either two or three UPI links inter-linking each socket (for more details see {{intel|skylake#Scalability|Skylake § Scalability|l=arch}}).

=== Common Features ===
All Skylake SP processors have the following:

* Hexa-channel memory
** 768 GiB / 1.5 GiB for extended memory variants (''M'' suffix)
** UP to DDR4-2666 MT/s
** [[ECC]] support
* '''TDP:''' 70 W to 205 W
* '''PCIe:''' x48 Lanes of PCIe Gen 3
* '''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|TSX}}, {{intel|TXT}}, {{intel|Volume Management Device}} (VMD), {{intel|Mode-based Execute Control}} (MBE), {{intel|Key Protection Technology}} (KPT), and {{intel|Platform Trust Technology}} (PTT).
** Silver and up also have {{intel|Hyper-Threading}} and {{intel|Turbo Boost}}
** Gold and up also have Node Controller Support and offer Integrated Omni-Path Fabric Interface options

Models that are suffixed with "''T''" have extended lifetime (10 year use) guarantees and [[NEBS]]-friendly packing specification. Additionally, models that are suffixed with "''F''" integrate the {{intel|Omni-Path}} Host Fabric Interface (HFI) die on-package.
