Support status

Sapphire Rapids is a codename for Intel's server (fourth generation Xeon Scalable) and workstation (Xeon W-2400 and Xeon W-3400) 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.

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] Sapphire Rapids 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] 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]

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.[27][26]

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
