Ice Lake (ICL, ICX) Server Configuration is Intel's successor to Cascade Lake, a 10 nm microarchitecture for enthusiasts and servers.

Release Dates[edit]

Ice Lake server processors were said to launch in the first half of 2021.

Process Technology[edit]

Cooper Lake and Ice Lake roadmap.
See also: Ice Lake (client) § Process Technology

Ice Lake will use a second-generation enhanced 10 nm process called "10 nm+". Versus the first generation 10 nm which was used for Cannon Lake, 10nm+ will feature higher performance through higher drive current for the same power envelope.

Architecture[edit]

Key changes from Cascade Lake[edit]

  • Enhanced "10nm+" (from 14 nm)
  • Sunny Cove core
    • See Sunny Cove for microarchitectural details and changes
  • I/O
    • PCIe 4.0 (from PCIe 3.0)
  • Memory
    • Higher bandwidth (190.7 GiB/s, up from 143.1 GiB/s)
    • Octa-channel (up from hexa-channel)
    • 3200 MT/s (up from 2933 MT/s)
    • Optane DC DIMMs
      • Apache Pass → Barlow Pass
  • Platform
  • Packaging
    • 4189-contact flip-chip LGA (up from 3647 contacts)

This list is incomplete; you can help by expanding it.

New instructions[edit]

Ice Lake introduced a number of new instructions. See Sunny Cove § New Instructions for details.
