Newly designed from the ground up, 45nm Intel Atom processors pack an astounding 47 million transistors on a single chip measuring less than 25mm², 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 performance-packed, 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 subwatt to 2.5 watts for mobile devices
* Extend battery life in select devices with an incredibly low idle power as low as 30 mW 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 performance and low power while maintaining full Intel® Core™ microarchitecture instruction set compatibility. Some future Intel Atom processors will also feature multiple threads for better performance and increased system responsiveness.
