Succession

Airmont is Intel's 14 nm microarchitecture for the Atom family of system on chips. Introduced in 2015, Airmont is a shrink of Silvermont.

Codenames[edit]

Platform Core Target
Braswell Braswell Netboooks, Tablets, Entry-level PCs

Process Technology[edit]

Main article: Broadwell § Process Technology

Airmont-based chips are manufactured on Intel's 14 nm process.

Architecture[edit]

Airmont is for the most part identical to Silvermont with some higher number of execution units to the GPU in some of the higher-end models.

Key changes from Silvermont[edit]

  • DTLB table size doubled (128 entries -> 256 entries)
  • L2 latency increased
  • Reorder Buffer was increased (from 32 entries to 48)
  • Gen 8 GPUs

Memory Hierarchy[edit]

  • Cache
    • Hardware prefetchers
    • L1 Cache:
      • 32 KiB 8-way set associative instruction, 64 B line size
      • 24 KiB 6-way set associative data, 64 B line size
      • Per core
    • L2 Cache:
      • 1 MiB 16-way set associative, 64 B line size
      • Per 2 cores
    • L3 Cache:
      • No level 3 cache
    • RAM
      • Maximum of 1 GiB, 2 GiB, and 4 GiB
      • dual 32-bit channels, 1 or 2 ranks per channel

Multithreading[edit]

Airmont, like Silvermont has no support for Intel Hyper-Threading Technology.

Pipeline[edit]
