Xeon Silver is a family of 64-bit x86 dual-socket multi-core mid-range performance server microprocessors introduced by Intel in 2017.

Overview

Released in July 2017, the Xeon Silver are the successor to the Xeon E5/E7 families. Xeon Silver is geared toward mid-range workloads dual-socket server. Xeon Silver processors are a set above the Xeon Bronze, offering additional features such as Hyper-Threading and Turbo Boost.

Members

4100-Series (Skylake)

First-generation Xeon Silver processors were introduced in July 2017. Those chips were fabricated on a enhanced 14nm+ process based on the Skylake microarchitecture which brought a relatively large SoC design change from the prior Xeon families. Those processors were the first to move to a mesh interconnect which introduced a tile-based architecture, bringing the first implementation of AVX-512 along with a rearchitected cache hierarchy designed for server workloads. All of the Silver 4100-series microprocessors feature dual-socket capabilities with up to 12 cores and 24 threads. Additionally, all Xeon Silver processors support:

• Proc: 14 nm process
• TDP: 85 W, 70 W
• Mem: 768 GiB hexa-channel DDR4-2400 ECC memory.
• I/O: 48 PCIe 3 lanes
• 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)
• Features: Hyper-Threading, Turbo Boost, 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).

All Xeon Silver processors support QuickAssist Technology which is integrated on the chipset as well as the Omni-Path Architecture on the chipset as well as via discrete PCIe cards. All models also support 2 Ultra Path Interconnect (UPI) links.
