− | 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 == | | == 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-channel 1 TiB of DDR4 ECC memory with up to 2 TiB and even 4.5 TiB for the medium memory and large memory tiers extended memory models. Cascade Lake also brings support for [[persistent memory]].
| + | {{empty section}} |
− | | |
− | 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 === | | === Common Features === |

| |
− | :[[File:cascade lake naming scheme.svg|600px]]
| |
− |
| |
− | Where,
| |
− |
| |
− | * "''F''" suffix integrates the {{intel|Omni-Path}} Host Fabric Interface (HFI) die on-package
| |
− | * "''L''" suffix indicates the SKU is a large memory (4.5 TiB) tier SKU
| |
− | * "''M''" suffix indicates the SKU is a medium memory (2 TiB) tier SKU
| |
− | * "''N''" suffix indicates the SKU is a networking-specialized model
| |
− | * "''S''" suffix indicates the SKU is a search application-specialized model
| |
− | * "''T''" suffix indicates that SKU has an extended lifetime (10 year use) guarantees and [[NEBS]]-friendly packing specification
| |
− | * "''U''" suffix indicates the SKU is a single-socket model (even if part of the [[Xeon Gold]] family that normally supports up two 4-way [[SMP]])
| |
− | * "''V''" suffix indicates the SKU targets the VM density value market
| |
− | * "''Y''" suffix indicates the SKU has {{intel|Speed Select Technology}} (SST)
