Intel® Atom™ Processor

Intel's smallest chip. Built with the world's smallest transistors¹.

"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 a new generation of powerful and energy-efficient companion devices, and all at affordable prices.

Designed from the ground up, 45nm Intel® Atom™ processors pack an astounding 47 million transistors on a single chip measuring less than 26mm², making them Intel's smallest and lowest power processors.¹ All this while delivering the power and performance you need to access all 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

The Intel® Atom™ processor was developed specifically for targeted performance and low power while maintaining Intel® architecture instruction set compatibility. Intel® Atom™ processors also feature Intel® Hyper-Threading Technology³ for better performance and increased system responsiveness.
