Airmont µarch
General Info
ERROR: "atype" is missing!

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

Platform Core Target
Cherry Trail Cherry Trail Smartphones, Tablets
Braswell Braswell Tablets, PCs

Architecture

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

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

    • RAM
      • Maximum of 1GB, 2 GB, and 4 GB
      • dual 32-bit channels, 1 or 2 ranks per channel

Multithreading

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

Pipeline
