'''Cascade Lake SP''' ('''{{intel|Cascade Lake|l=arch}} Scalable Performance''') is code name for Intel's series of server [[multiprocessors]] based on the {{intel|Cascade Lake|l=arch}} microarchitecture as part of the {{intel|Purley|l=platform}} platform serving as the successor to {{intel|Skylake SP|l=core}}. These chips support up to 8-way multiprocessing, up to [[28 cores]], incorporate a new {{x86|AVX512-VNNI|AVX512}} [[x86]] {{x86|extension}} for neural network / deep learning workloads, and introduces [[persistent memory]] support. Cascade Lake SP-based chips are manufactured on an enhanced [[14 nm process|14nm++ process]] and utilize the {{intel|Lewisburg|l=chipset}} chipset.

Cascade Lake SP-based models are branded as the 2nd-generation {{intel|Xeon Bronze}}, {{intel|Xeon Silver}}, {{intel|Xeon Gold}}, and {{intel|Xeon Platinum}} [[processor families]].


== Overview ==
Cascade Lake SP processors are based on Intel's {{intel|Cascade Lake|l=arch}} microarchitecture which brings a modest frequency improvement due to an enhancement process technology along with {{intel|DL Boost}}, an {{x86|extension}} designed to speed up machine learning algorithms. 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 ? GiB of DDR4 ECC memory or ? TiB for extended memory models. Cascade Lake also brings support for [[persistent memory]].

As with {{\\|Skylake SP}}, Cascade Lake 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|cascade lake#Scalability|Cascade Lake § Scalability|l=arch}}).

=== Common Features ===
All Cascade LAke SP processors have the following:

* Hexa-channel memory
** 1 TiB, 2 TiB medium memory support variants (''L'' suffix), and 4.5 TiB for extended memory variants (''L'' suffix)
** UP to DDR4-2933 MT/s
** [[ECC]] support
* '''TDP:''' 85 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, AVX512VNNI)
* '''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''" (CSL-F) integrate the {{intel|Omni-Path}} Host Fabric Interface (HFI) die on-package.
