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. Cascade Lake W series of processors are branded as the Xeon W family.
Overview[edit]
Cascade Lake W are enterprise workstation microprocessors. Those are a two-chip solution consisting of the microprocessor and the Lewisburg chipset. All processors are socket FCLGA-3647, 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[edit]
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: 1 TiB of quad-channel DDR4-2933 ECC Memory
- M models support 2 TiB of memory
- DPC RDIMM and LRDIMM \w ECC
- I/O: 64 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 with 2 FMA units)
- 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).
Cascade Lake W Processors[edit]
Note that for the lower core-count models, the L3 cache size is larger than it would otherwise be due to additional cache slices being enabled from disabled cores.
