Cascade Lake (CSL) 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.

Release Dates

Cascade Lake is expected to be released in mid-2018.

Process Technology

Cascade Lake is fabricated on Intel's 3rd generation enhanced 14nm++ process.

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

  • Architectural improvements (specifics unknown yet)
  • Core
  • Package
    • Selected SKUs with Arria 10 FPGAs in a MCP
  • Memory
    • 2933 MT/s DDR4 (up from 2666 MT/s)
    • Support for DDR-T / Optane DIMMs
