The Intel Atom processor is based on an entirely new microarchitecture designed specifically for small devices and low power, while maintaining the Intel Core 2 Duo instruction set compatibility consumers are accustomed to when using a standard PC and the Internet. The design also includes support for multiple threads for better performance and increased system responsiveness. All of this on a chip that measures less than 25 mm2, making it Intel’s smallest and lowest power processor yet.1 Up to 11 Intel Atom processor die — the tiny slivers of silicon packed with 47 million transistors each — would fit in an area the size of an American penny.
These new chips, previously codenamed Silverthorne and Diamondville, will be manufactured on Intel’s industry-leading 45nm process with hi-k metal gate technology. The chips have a thermal design power (TDP) specification in 0.6-2.5 watt range and scale to 1.8GHz speeds depending on customer need. By comparison, today’s mainstream mobile Core 2 Duo processors have a TDP in the 35-watt range.
