Intel discontinued Cascade Lake-X and Cascade Lake-W products

In 2019, Intel unveiled Cascade Lake, an optimized version of Skylake, which includes Cascade Lake-X for HEDT, Cascade Lake-W for workstations, and Cascade Lake-SP and Cascade Lake-AP for servers. All are fabricated using a 14nm process. Intel has ceased production of Cascade Lake-X and Cascade Lake-W products, as revealed in a recent Product Change Notification (PCN).

Cascade Lake-X is used for the Core X series, encompassing the Core i9-10980XE Extreme Edition, the Core i9-10940X, the Core i9-10920X, and the Core i9-10900X processors. Intel’s abandonment of the HEDT market is not recent, with Cascade Lake-X representing the last batch of HEDT processors. While there have been rumors of Intel reentering the HEDT market with Sapphire Rapids, such a move has not yet been executed.

Compared to Cascade Lake-X, Intel offers a more diverse range of choices based on Cascade Lake-W, such as the Xeon W-2200 series, extending from the quad-core Xeon W-2225 to the 18-core Xeon W-2295. Notably, Intel’s subsequently launched Xeon W-3200 series was also built on Cascade Lake-W, with the current cessation of production pertaining solely to the Xeon W-2200 series. With the advent of Sapphire Rapids this year, Intel has reallocated resources, with older products being predominantly replaced by the Xeon W-2400/3400 series.

The cessation of production does not immediately entail the halt of Cascade Lake-X and Cascade Lake-W supplies. Customers have a fairly extensive grace period to order these 14nm products. Orders can be placed until April 26, 2024, with Intel planning to deliver until January 31, 2025.

Theoretically, the corresponding chipsets will also cease to be supported. Intel plans to include this information in a separate Product Change Notification, involving the X299 and C422 chipsets. In actuality, these chipsets were launched as early as 2017, prior to the appearance of Cascade Lake. The corresponding LGA 2066 socket has supported three generations of products: Skylake, Kaby Lake, and Cascade Lake.
