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

Overview[edit]

Skylake SP processors are based on Intel's Skylake 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 TiB for extended memory models.

Skylake SP processors utilize the new FCLGA-3647 package (which makes use of "Socket P"). Those use the Lewisburg chipset (HUB) via 4 PCIe3 lanes using Intel's proprietary 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 Ultra Path Interconnect (UPI) links which Intel introduced with Skylake SP as well, replacing and obsoleting the older 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 Skylake § Scalability).

Common Features[edit]

All Skylake SP processors have the following:

Hexa-channel memory
- 768 GiB / 1.5 TiB 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: Speed Shift, vPro, VT-x, TSX, TXT, Volume Management Device (VMD), Mode-based Execute Control (MBE), Key Protection Technology (KPT), and Platform Trust Technology (PTT).
- Silver and up also have Hyper-Threading and 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" (SKL-F) integrate the Omni-Path Host Fabric Interface (HFI) die on-package.
