Sapphire Rapids is a codename for Intel's server (fourth generation Xeon Scalable) and workstation (Xeon W-2400/2500 and Xeon W-3400/3500) processors based on the Golden Cove microarchitecture and produced using Intel 7. [1] [2] [3] [4] It features up to 60 cores and an array of accelerators, and it is the first generation of Intel server and workstation processors to use a chiplet design.

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

History

Sapphire Rapids has been a long-standing Intel project along Alder Lake in development for over five years and has been subjected to many delays. [8] It was first announced by Intel at their Investor Meeting in May 2019 with the intention of Sapphire Rapids succeeding Ice Lake and Cooper 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] Those processors were available for shipping on March 14 of that year. [17] Intel shipped the millionth of this generation Xeon processors in 2023. [18]

Features

CPU

Accelerators

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 kernel version 6.2. [29] [28]

I/O

Die configurations

Sapphire Rapids come in two varieties: the low-core-count variety uses a single die (MCC), and the high-core-count variety uses multiple dies on a single package (XCC).

XCC multi-die configuration

  • Multi-chiplet chip with four tiles linked by 2.5D Embedded Multi-die Interconnect Bridges. Each tile is a 400mm2 system on a chip, providing both compute cores and I/O. [32]
    • Each tile contains 15 Golden Cove cores, and a single UPI link
    • Each tile's memory controller provides two channels of DDR5 ECC supporting 4 DIMMs (2 per channel) and 1 TB of memory with a maximum of 8 channels, 16 DIMMs, and 4 TB memory across 4 tiles [33]
    • 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 (20 per tile). [34]

<span class="mw-page-title-main">Xeon</span> Line of Intel server and workstation processors

Xeon is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for error correction code (ECC) memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus, which replaced the older QuickPath Interconnect (QPI) bus.
