Sapphire Rapids is part of the Eagle Stream server platform.[5][6] In addition, it will be powering Aurora, an exascale supercomputer in the United States, at Argonne National Laboratory.[7]

History

Sapphire Rapids has been a long-standing Intel project in development for over five years and has been subjected to many delays.[8] Sapphire Rapids was first announced by Intel at their Investor Meeting in May 2019 with the intention of Sapphire Rapids succeeding Ice Lake in 2021.[9][10] Intel again announced details on Sapphire Rapids in their August 2021 Architecture Day presentation with no mention of a launch date.[11] Intel CEO Pat Gelsinger tacitly blamed the previous Intel leadership as a reason for Sapphire Rapid's many delays.[8] One industry analyst firm claimed that Intel was having problems with yields from its Intel 7 node with yields of 50–60% on higher core-count silicon.[12] Sapphire Rapids was originally scheduled for a launch in the first half of 2022.[13] It was later scheduled for release in Q4 2022 but was again delayed to early 2023.[14] The specific announcement date of January 10, 2023 was not revealed by Intel until November 2022.[15] The server processor lineup was released on January 10, 2023, and the workstation processor lineup was released on February 15, 2023.[16] Nevine Nassif is a chief engineer for this generation.[17] Those processors were available for shipping on March 14 of that year.[18] Intel shipped millionth of this generation Xeon processors at 2023.[19]

Features

CPU

  • Up to 60 Golden Cove CPU cores per package[20]
  • AVX512-FP16[21]
  • TSXLDTRK[22]
  • Advanced Matrix Extensions (AMX)[20]
  • Trust Domain Extensions (TDX), a collection of technologies to help deploy hardware-isolated virtual machines (VMs) called trust domains (TDs)[23]
  • In-Field Scan (IFS), a technology that allows for testing the processor for potential hardware faults without taking it completely offline[24]
  • Data Streaming Accelerator (DSA), allows for speeding up data copy and transformation between different kinds of storage[25][26]
  • QuickAssist Technology (QAT), allows for improved performance of compression and encryption tasks[26]
  • Dynamic Load Balancer (DLB), allows for offloading tasks of load balancing, packet prioritization and queue management[26]
  • In-Memory Analytics Accelerator (IAA), allows accelerating in-memory databases and big data analytics[26]

Not all accelerators are available in all processor models. Some accelerators are available under the Intel On Demand program, also known as Software Defined Silicon (SDSi), where a license is required to activate a given accelerator that is physically present in the processor. The license can be obtained as a one-time purchase or as a paid subscription. Activating the license requires support in the operating system. A driver with the necessary support was added in Linux 6.2.[27][26]

I/O

XCC multi-die configuration

  • Multi-die chip with four tiles linked by 2.5D Embedded Multi-die Interconnect Bridges. Each tile is a 400mm2 SoC, providing both compute cores and I/O.[31]
    • Each tile contains 15 Golden Cove cores
    • Each tile's memory controller provides two channels of DDR5 with a maximum of eight channels across 4 tiles[32]
    • A tile provides up to 32 PCIe 5.0 lanes, but one of the eight PCIe controllers of a CPU is usually reserved for DMI, resulting in a maximum of 112 non-chipset lanes. This maximum is only reached in the W-3400 series processors, while the server processors have 80.[33]
  • Xeon Max processors also contain 64 GB of High Bandwidth Memory

Sapphire Rapids-WS (Workstation)

With its maximum of 56 cores, Sapphire Rapids-WS competes with AMD's Threadripper Pro 5000WX with up to 64 cores.[36] Like Intel's Core product segmentation into i3, i5, i7 and i9, Sapphire Rapids-WS is labeled Xeon w3, w5, w7 and w9.[37] Sapphire Rapids-WS was unveiled in February 2023, and will be initially available for OEMs in March.[38][39] CPUs with "X" suffix have its multiplier unlocked for overclocking.[40]

  • CPU models ending with X are overclockable, others are not.
