Intel® Atom™ Processor
Intel's smallest chip. Built with the world's smallest transistors¹.
The 45nm Intel Atom processor is a tiny sliver of silicon

"This is our smallest processor built with the world's smallest transistors. The Intel® Atom™ processor is based on an entirely new design, built for low power and designed specifically for a new wave of Mobile Internet Devices and simple, low-cost PC's. This small wonder is a fundamental new shift in design, small yet powerful enough to enable a big Internet experience on these new devices. We believe it will unleash new innovation across the industry."

– Intel Executive Vice President Sean Maloney

As Intel's smallest and lowest power processor², the Intel® Atom™ processor enables the latest Mobile Internet Devices (MIDs), and another new category of devices for the internet called netbooks and nettops. It's also the foundation for the all new Intel® Centrino® Atom™ processor technology, a collection of chips enabling amazing Internet experiences in pocketable devices.

Intel® Atom™ processorIntel® Centrino® Atom™ processor technologyNewly designed from the ground up, 45nm Intel® Atom™ processors pack an astounding 47 million transistors on a single chip measuring less than 22mm², making them Intel's smallest and lowest power processors.¹ All this while delivering the power and performance you need for full Internet capabilities.+

* Get a new range of power-efficient devices with excellent performance enabled by all new hafnium-infused 45nm high-k silicon technology
* Increase energy efficiency in smaller more compact designs with a thermal design power specification ranging from less than 1W to 2.5 watts for mobile devices
* Extend battery life in select devices with an incredibly low idle and average power allowing the device to stay powered on while also conserving energy

Based on an entirely new microarchitecture, the Intel® Atom™ processor was developed specifically for targeted performance and low power while maintaining full Intel® Core™ microarchitecture instruction set compatibility. Intel® Atom™ processors also feature multiple threads for better performance and increased system responsiveness.
