Intel® Atom™ Processor Microarchitecture

Newly designed from the ground up, the Intel® Atom™ processor is based on entirely new hafnium-based 45nm microarchitecture. Representing Intel's smallest and lowest power processor yet¹, the Intel® Atom™ processor enables a new generation of powerful and energy-efficient Mobile Internet Devices (MIDs) and a new category of simple devices for the internet called netbooks and nettops that will be available at affordable prices.

Delivering new design possibilities due to its remarkably small size and performance-per-watt advantages, the Intel Atom processor provides:

* Performance for a great internet experience in a range of sub 1 watt to 4 watt thermal power envelope based on industry leading benchmarks (EEMBC) and web page rendering performance
* Greater energy efficiency for mobile devices enabled by incredibly low average power and idle power, scaling performance from 800MHz to 1.86GHz
* Power-optimized front side bus of up to 533MHz for faster data transfer on demanding mobile applicationsΔ
* Scalable performance and increased power efficiency with multi-threading support²
* Improved performance on multimedia and gaming applications with support for Streaming SIMD Extensions 3 (SSE3)
* Improved power management with new Deep Power Down (C6) enabled on the Intel® Atom™ processor Z5xx series for MIDs, and extended C4 states enabled on Intel® Atom™ processor N270 for netbooks, in addition to non-grid clock distribution, clock gating, CMOS bus mode, and other power saving architectural features
* Low TDP enabled by improved power management technologies delivering high performance to run the real Internet and a broad range of software applications³
