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
Cherry Trail	Cherry Trail	Lightweight tablets / High-end Smartphones
Riverton	Riverton	Smartphones (HSPA+, LTE Category 3, and TD-SCDMA)
Binghamton	Binghamton	Smartphones (3G only)

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

Block Diagram[edit]

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]

Main article: Silvermont's Pipeline

Airmont's pipeline is identical to Silvermont's.

Cores[edit]

Cherry Trail - SoCs for Smartphones/Tablets
Braswell - SoCs for low-end PCs

All Airmont Chips[edit]
