Xeon E5

Xeon W is a family of enterprise-class 64-bit multi-core x86 performance workstation microprocessors.

Overview

The Xeon W family targets business and enterprise-class performance workstations, situated below the scalable Xeon family and above the Xeon E3. Compared to the Xeon E3, Xeon W come with more cores, more PCIe lanes, ECC memory, generally almost all available technologies offered by the chip, volume management and various RAS features.

Originally introduced in August 2017, the Xeon W family is Intel's family of workstation-class processors. Prior to their introduction, this segment was served by Xeon E5 family 1600-series. Prior to Skylake, the server segment and high-HEDT as well as workstations shared the same socket. With Skylake, the server segment diverged with the workstations and HEDT parts having their own socket. The Xeon W family and the HEDT Core i7/Core i9 parts share the same socket.

The Xeon W family is split into two series - 2000 and 3000 - where the 3000 is positioned above the 2000-series lineup in the product stack. The major difference between the two is that the 3000-series uses the same platform and socket as the mainstream Xeon Scalable lineup while the 2000-series processors use the enthusiasts platform. Because of that, the 3000 series can provide some additional features such as higher core-count and I/O compared to the 2000-series.

Naming scheme

Xeon W SKUs follow the following naming scheme.

Members

W-2000

The W-2000 series is the mainstream workstation series.

W-2100-Series (Skylake)

Main article: Skylake (server) Microarchitecture

Skylake-based Xeon W processors come with all the features enabled and only core count and frequency being the differentiating feature, with the exception of the two low-end models. For the most part, all models come with AVX-512 along with two full execution units, similar to the high-end Skylake SP models. All models have 48 PCIe lanes and have all the following features in common:

• Bus: DMI 3.0
• Mem: 512 GiB of quad-channel DDR4-2666 ECC Memory
• I/O: 48 PCIe 3.0 Lanes
• TDP: 120 W / 140 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 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).

Note that B models appear to be a special variant for Apple's iMac Pros.

W-3000

Xeon W 3000 series was derived from the SP line of server processors, because those had dies with more than 18 cores. As such this line of processors uses Socket 3647 like the Xeon SP series. Since they are limited to single socket they possess no UPI-Links or Intel Omni-Path.

W-3200-Series (Cascade Lake)

Main article: Cascade Lake Microarchitecture

In early 2019 Intel launched their W-3200 series processors based on the Cascade Lake microarchitecture. Those processors are fabricated on an enhanced 14 nm process which allows for higher clock speeds and introduced a number of hardware changes against the various speculative execution vulnerabilities. Those processors also introduced new new instructions for the acceleration of machine learning (inference), Turbo Boost Max, and increased the PCIe lanes to 64. All processors also have the following features in common:

• Proc: 14 nm process
• Bus: DMI 3.0
• Mem: 1 TiB of hexa-channel DDR4-2933 ECC Memory
  • "M" models have 2 TiB extended memory support
• I/O: 64 PCIe 3.0 Lanes
• TDP: 160 W, 180 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).
