Specifications of the first wave of next-generation Intel Atom system-on-chips for various “Bay Trail” platforms have been published in China. As expected, the new products will cut down power consumption of chips for low-cost/low-power notebooks. Many of the consumer-oriented Bay Trail products will be marketed under Pentium and Celeron brands. Finally, in addition to tablets, notebooks and desktops, the new SoCs will also target industrial applications.


As previously announced, various versions of desktop-oriented Celeron and Pentium processors with four or two cores will feature high clock-speeds, high-performance graphics engine as well as 10W thermal design power (TDP). By contrast, Pentium and Celeron chips for low-cost/low-power notebooks and convertibles will offer different levels of performance and will have 4.5W – 7.5W thermal design power; some of such products will even support 2.5W scenario design power. Finally, there will be Atom-branded system-on-chips for industrial applications with one to four cores and 5W – 10W TDP.

The new Intel Atom, Celeron and Pentium processors for desktops, mobile and industrial applications based on Silvermont micro-architecture are expected to be formally introduced later this year.

Silvermont: Next-Generation Microarchitecture

Silvermont will serve as the foundation for a breadth of 22nm products expected in market later this year. The performance-per-watt improvements with the new microarchitecture will enable a significant difference in performance and responsiveness for the compute devices built around these products. Intel's Silvermont microarchitecture was designed and co-optimized with Intel's 22nm SoC process with tri-gate transistors. By taking advantage of this industry-leading technology, Intel is able to provide a significant performance increase and improved energy efficiency.

Highlights of the Silvermont microarchitecture include:
