'''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]] and utilize the {{intel|Lewisburg|l=chipset}} chipset. | '''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}}.

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}}). | As with {{\\|Skylake SP}}, Cascade Lake SP processors utilize the new {{intel|FCLGA-3647}} package (which makes use of "Socket P").
