Atom is an family of ultra-low-voltage 32 and 64-bit microprocessors and system on chips designed by Intel since 2008.
Models
Bonnell
- Main article: Bonnel Microarchitecture
Bonnell was the first microarchitecture designed specifically for the ultra-low power microprocessor market. Introduced in 2008, it featured fully x86-compatible cores with a TDP of only 500 mW to 2 W, less than any other x86 processor available that the time. All Bonnell-based processors were manufactured on Intel's 45 nm process.
Silverthorne Core

- Main article: Silverthorne Core
The first series of Bonnell processors were introduced during the 2008 Intel Developer Forum (IDF) in Shanghai, China. Those 32-bit processors were based on the the Silverthorne core which were designed for the Mobile Internet Devices (MID) market. Silverthorne processors have 56 KiB of L1$ and 512 KiB of L2. Silverthorne has support for the traditional AGTL+-based FSB as well as a new low power CMOS FSB specifically introduced to reduce power.
Silverthorne chips consist of 47 million transistors on a 4.2 mm² die packaged in a tiny 13mm x 14mm FCBGA-437 and PBGA-441 packages. All processors are a single core with Hyper-Threading. Additionally all models support every x86 extension up to SSSE3 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3).
