Xeon E7 Xeon E5

Xeon Bronze is a family of 64-bit x86 dual-socket multi-core entry-level server-class microprocessors introduced by Intel in 2017.

Overview

Released in July 2017, the Xeon Bronze are the successor to the Xeon E5/E7 families. Xeon Bronze is geared toward entry-level dual-socket server and workstation microprocessors. Those processors are ideally positioned for price-sensitive applications which require light-range workloads with enhanced security features and large memory. Additionally, those processors incorporate a number of Ultra Path Interconnect (UPI) links. Unlike the higher tier Xeon families, the Xeon Bronze doesn't have Turbo Boost Technology or Hyper-Threading support.

3100-Series (Skylake)

See also: Skylake µarch

First-generation Xeon Bronze 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 bronze 3100-series microprocessors feature dual-socket capabilities with up to 8 cores and 8 threads. Additionally, all Xeon Bronze processors support:

• Proc: 14 nm process
• TDP: 85 W
• Mem: 768 GiB hexa-channel DDR4-2133 ECC memory.
• I/O: 48 PCIe Gen 3.0 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: 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 Bronze 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.

Second-generation Xeon Scalable Bronze was introduced in early 2019. Those processors are fabricated on an enhanced 14 nm process based on the Cascade Lake microarchitecture 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) as well as support for persistent memory. All 3200-series Xeon Bronze processors support:

• TDP: 85 W
• Mem: 1 TiB hexa-channel DDR4-2133 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/VNNI)
• 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).

All Xeon Bronze 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.
