Cascade Lake R (Cascade Lake Scalable Performance Refresh) is code name for Intel's series of server multiprocessors based on the Cascade Lake microarchitecture as part of the Purley platform serving as mid-cycle refresh to Cascade Lake SP. Cascade Lake R only targets mainstream entry and mid-range servers and therefore only support up to 2-way multiprocessing. As with Cascade Lake SP, these chips also support up to 28 cores, incorporate AVX512 x86 extension for neural network / deep learning workloads, and introduces persistent memory support. Cascade Lake R-based chips are manufactured on an enhanced 14 nm process and utilize the Lewisburg chipset.

Cascade Lake R-based models are branded as the 2nd-generation Xeon Bronze, Xeon Silver, and Xeon Gold processor families.

Overview[edit]

Cascade Lake R processors are based on Intel's Cascade Lake microarchitecture intended to enhance the original Cascade Lake SP lineup. These processors introduce a significant price cut compared to original SKUs or additional cores and the higher frequency at comparable price. The intended purpose of this release is to elevate the performance-per-dollar for entry-level and mid-range server processors.

As with Skylake SP, Cascade Lake 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 Cascade Lake § Scalability).

Common Features[edit]

All Cascade Lake R processors have the following:

Hexa-channel memory
- 1 TiB, 2 TiB medium memory support variants (M 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: 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

Naming Scheme[edit]

Cascade Lake SKUs follow the following naming scheme.

Where,

"F" suffix integrates the 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
"V" suffix indicates the SKU targets the VM density value market
"Y" suffix indicates the SKU has Speed Select Technology (SST)
"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)
"R" suffix indicates the SKU is a dual-socket model (even if part of the Xeon Gold family that normally supports up two 4-way SMP)
