Cascade Lake (CLX) Server Configuration is Intel's successor to Skylake, a 14 nm microarchitecture for enthusiasts and servers. Cascade Lake is the "Optimization" phase as part of Intel's PAO model.
For desktop enthusiasts, Cascade Lake is branded Core i7, and Core i9 processors (under the Core X series). For scalable server class processors, Intel branded it as Xeon Bronze, Xeon Silver, Xeon Gold, and Xeon Platinum.

Architecture
As with Skylake, Cascade Lake is also based on the Purley platform and is designed as a drop-in upgrade.
Key changes from Skylake
- Supports higher DDR4 data rates
- Support for DDR-T / Optane DIMMs
- Architectural improvements
- Security
- Fix for CVE-2017-5715 (Spectre, Variant 2)
- Fix for CVE-2017-5754 (Meltdown, Variant 3)
This list is incomplete; you can help by expanding it.
New instructions
Cascade Lake introduced a number of new instructions:
-
AVX-512 VNNI- AVX-512 Vector Neural Network Instructions
