Cascade Lake W (Cascade Lake Workstations; CLS-W) is codename for Intel's enterprise workstation microprocessor line based on the Cascade Lake microarchitecture, succeeding Skylake W. Cascade Lake W processors feature a number of enhancements including a new AVX512 x86 extension for neural network / deep learning workloads, and introduces persistent memory support.
Overview
Cascade LAke W are enterprise workstation microprocessors. Those are a two-chip solution consisting of the microprocessor and the C422 chipset. All processors are socket Socket R4 (LGA-2066), manufactured on Intel's enhanced 14++ nm process based on the Skylake microarchitecture. Those are single-socket chips only. Geared toward business workstations, those processors come with all the related features such as vPro, Volume Management Device (VMD), and RAS.
Common Features
For the most part, Cascade Lake W processors come with all the features enabled and only core count and frequency being the differentiating feature. It's worth pointing out that the Skylake W come with AVX-512 along with two full execution units, similar to the high-end Skylake SP models (with the exception of the two low-end models). All models have 48 PCIe lanes and have all the following features in common:
- Mem: 512 GiB of quad-channel DDR4-2933 ECC Memory
- DPC RDIMM and LRDIMM \w ECC
- I/O: 48 PCIe 3.0 Lanes
- TDP: 160 W - 205 W
- ISA: Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2, AVX-512-F/CD/BW/DQ/VL/VNNI)
- Features: Speed Shift, vPro, VT-x/EPT, VT-d, TBT 2.0, TSX, TXT, SpeedStep, Identity Protection, Secure Key, MPX, OS Guard, and Volume Management Device (VMD).
